What effect does Natural Lutein Powder have
Since the Ministry of Agriculture and Rural Affairs announced that 2045 expanded the application scope of natural lutein (from marigold) to aquatic animals, the addition of aquatic feed in China has become increasingly common.The natural lutein extracted from marigold is safe and effective.
Its main pigment composition is similar to the carotenoid components in many aquatic animals. The addition and applied to aquatic animal feed has played a key role in solving the body color problem of many aquatic animals
However, many insiders are still unknown about the characteristics of natural lutein and its application in aquatic feed. This article summarizes a large number of research results at home and abroad, in order to provide reference for relevant practitioners
Because lutein is non-toxic and harmless, it has a good effect on preventing human aging.Yeltein and lutein luferase are selling well in the American breeding market.With the development of China’s food crystal industry and the national attention to health food, lutein health food will have a broad prospect in the market
A Brief Introduction to Natural Lutein Powder
Natural lutein is a large class of aerobic carotenoids widespread in nature, orange or orange yellow, mainly from plants and algae, representative components are yellow voxel (Lutein) and zeaxanthin (Zeaxanthin)
The composition of natural lutein varies greatly in different plants, among which the content of natural lutein in marigold flowers is much higher than that in general plants, which can be planted on a large-scale with mature extraction and processing technology.
Currently, it has formed a perfect industrial chain and is a high-quality raw material for natural lutein production.The natural lutein extracted from marigold is safe and effective, and has been widely used in food, medicine, feed and other fields
What effect does Natural Lutein Powder have on human body
Natural lutein has important physiological functions for the human body and animal bodies.It have shown that the retinal macular area is rich in carotenoids, mainly yellow voxel and zeaxanthin, which plays a crucial role in protecting the eye. The mechanism is filtering blue light with phototoxic effects and ququenching singlet oxygen.
Natural lutein is an effective substance to remove oxygen free radicals, which can reduce the oxidative damage of toxic substances, thus having significant biological activities in controlling cancer, cardiovascular disease and enhancing body immunity
Safety of Natural Lutein Powder
At present, most of the natural lutein raw materials produced in the market come from marigold.marigold is an ancient traditional flower, native to Mexico and often cultivated as an ornamental flower.
It is also an important plant of medicine and food. Its petals have the effect of clearing heat, heat and detoxification
As a product of food, health products for use, the safety of natural lutein has been assessed and recognized by domestic and foreign authorities such as the US Food and Drug Administration (FDA) and approved as a food supplement for food, beverage in 1995
Yeltein is a non-toxic substance and can be developed and used as a food additive and health food raw materials.In fact, natural lutein has many benefits to human health. At present, it has been widely used in food and health care products, such as many high-end infant milk powder, and the effective ingredients on the market are chewing tablets, capsules and lozenges.
Overview of Natural Lutein Powder applications
Animals themselves cannot synthesize lutein, and add natural lutein extracted from marigold to the feed to improve the quality of animal products and production performance. It has a long history at home and abroad, and was widely used in Europe many years ago
Not only that, lutein has strong coloring ability, and rich in nutrition, is an excellent food coloring agent and animal feed additive 11. Therefore, lutein is widely used in medicine, health care products, cosmetics, food, animal feed, aquatic products, tobacco and other lines
Improvement effect of Natural Lutein Powder on body color in aquatic animals
Aquatic animals in the wild state mainly feed on natural bait rich in natural lutein, such as zooplankton, fish and shrimp, etc., and deposited in the body through the food chain, so that aquatic animals present a beautiful and bright natural and healthy color.
The main pigment composition of natural lutein is similar to the carotenoid components in many aquatic animals. Addition to animal feed is easy to be easily absorbed, deposited and utilized by aquatic animals, and the coloring effect is natural and beautiful, similar to aquatic animals in wild state
Improvement effect of Natural Lutein Powder on the antioxidant capacity of aquatic animals
Like many plant extracts, natural lutein has the effect of improving the body antioxidant, adding it to aquatic animal feed, can improve some aquatic animal antioxidant indicators
Nutritional value of Natural Lutein Powder to aquatic animals
Natural lutein has a certain vitamin A precursor effect on aquatic animals, especially freshwater fish
Improvement effect of Natural Lutein Powder on the growth performance of aquatic animals
Natural lutein also has a certain role in improving animal growth performance.
Natural lutein can significantly stimulate some gastrointestinal digestive enzymes in yellow catfish, thus improving the utilization rate of feed and the digestibility rate of nutrients, and finally showing a growth-promoting effect
Note for Natural Lutein Powder use
Aquatic animal coloring is a systematic engineering, closely related to the aquatic animals themselves, the feed formula technology, and the regulation and management of pigment cells are the key elements
Aquatic animal pigment cells include melanocytes, red pigment cells, yellow pigment cells and iris cells, natural lutein is mainly deposited in red pigment cells and yellow pigment cells, a small part is also deposited in fat and muscle
Since the deposition of natural lutein mainly depends on the growth and development of pigment cells, which need to undergo a physiological development process, its stable deposition takes a certain time, and cannot be unlimited deposition, and there is a certain “saturation” phenomenon
Where does Natural Lutein Powder exist
Lutein is a natural yellow voxel containing two different violetone rings, which is a carotenoid without vitamin A activity. It is widely found in vegetables, fruits, flowers, etc. It is an important pigment in the retinal macular area of the human eye
What can Natural Lutein Powder do
Yeltein contains a unique violone ring dihydrohydroxyl structure that can serve as a strong antioxidant to quench singlinear oxygen and blue light filters, with the biological effects of antioxidant, anticancer, retina protection and cardiovascular disease prevention.However, the physicochemical nature of lutein is unstable, with poor water solvent, unstable nature and low bioavailability in the preparation process
The physicochemical properties of Natural Lutein Powder
Natural lutein is mainly composed of two different acetone rings coupled with a long chain of conjugated double bonds containing 18-carbon atoms, with three chiral centers, eight stereoisomers with rhombic-shaped bright yellow crystals with metallic luster and can better absorb blue light and purple light
The in vivo process of Natural Lutein Powder
Lutein with lipid-forming micelle is ingested into the body, released from the stomach under the action of various enzymes, absorbed into enterocytes and transported into the liver with the lymphatic or portal vein into the liver.
Transformation in the liver and released with low density lipoprotein (LDL) into the circulation, a fraction of lutein in the blood binds to other corresponding vectors into the retina and other tissues
Absorption and distribution of Natural Lutein Powder
Lutein synthetase is not present in humans, so lutein is only obtained by dietary uptake.Lutein in food binds to lipids into mixed lipid micelles that are absorbed by the body by transport or cholesterol carriers through passive diffusion.
Protective effects on the retina
The retina has a large vascular distribution and higher oxygen concentrations, and contains photosensitive compounds and readily oxidized substrates.Under high energy light conditions, oxygen radicals are easily generated, leading to lipid peroxidation of retinal cells, causing allosteric and DNA damage of intracellular proteins, and ultimately leading to apoptosis of retinal cell apoptosis.
Preventive effect on cardiovascular disease of Natural Lutein Powder
The accumulation of cholesterol and LDL in the human body leads to arterial blood tube closure, thickening, loss of elasticity of blood vessel wall cells, and then causes cardiovascular diseases such as atherosclerosis.Lutein can inhibit LDL lipid peroxidation through antioxidant effects, which can thereby delay the formation of arterial plaque and prevent the occurrence of atherosclerosis and other arterial cardiovascular disease.
Changes in the middle intima thickness of the main carotid artery are related to the blood lutein content, and the vascular wall thickness is inversely related to lutein content within certain conditions and ranges.
Lutein is also able to inhibit LDL oxidative modification and prevent smooth muscle cell proliferation
antitumous effect of Natural Lutein Powder
At present, the anti-cancer action mechanism of lutein is not clear, mainly believed to be the following:
(1) lutein can quench monlinear oxygen, prevent the occurrence of lipid peroxidation, thus inhibiting tumor growth.
The study of Sun Guogui et al found that compared with normal hepatocytes, the excess ROS could cause damage to nuclear DNA, mutations in mitochondrial DNA, peroxidation of proteins and lipids.
(2) Yeltein can enhance humoral immunity and cellular immunity in the body and inhibit the growth of cancer cells in the body.The presence of polar genes at the structural ends of lutein may enhance the growth of antigen lymphocytes and influence the functional expression of cell surface molecules
Natural Lutein Powder Main dosage form study of lutein
When lutein is used in clinical or food products, it is mainly faced with problems of poor water solvent, unstable nature and low bioavailability.
In the process of preparation, storage, processing, heterogeneous and oxidation, which need to change the dosage form by physical embedding and chemical modification (such as esterification reaction) to improve its bioavailability
Natural Lutein Powder Oil suspension
Lutein crystals were ultracrushed to a micrometer level, adding vegetable oil and antioxidants, and properly stirred to prepare an oil suspension containing about 20% lutein.
Natural Lutein Powder Water dispersion dry powder
Water dispersion dry powder is prepared as a solid dispersion by a lutein in a microcrystalline, amorphous, colloidal dispersion or molecular dispersion and a suitable vector that can diffuse in cold water
Natural Lutein Powder microcapsule
Microcapsules are drugs embedded in tiny capsules and released under certain conditions, with a general particle size between 0.7~5 µm.Traditional microcystic preparations have too large particle size and low surface effect, so Chinese and foreign scholars explore the nanopere and nanopcapsule composite system to bury lutein
Natural Lutein Powder liposome
Liposome is a new dosage form of microcapsule. As a nanocarrier delivery function factor, it has a small particle size, large surface area, and is non-toxic, unimmunogenic and biodegradable, which can increase drug solubility and promote its absorption in the human body
Lutein has excellent free radicals and light shielding, is a natural antioxidant; extensive biological effects, anti-tumor and immune regulation, anti-cardiovascular disease, and can effectively prevent and treat ocular macular diseases (such as cataract, age retinopathy, diabetic retinal degeneration, etc.), with great potential in developing drugs to treat ocular macular diseases
The metabolism and transformation of carotenoids of Natural Lutein Powder
Carcarotenoids contain carotenoids and lutein and are only synthesized by plants and microorganisms.Common dietary intake in organs and tissues include α-carotene, β-carotene and lycopene, while lutein mainly includes lutein, zeaxanthin and β-cryptoxanthin
Polarity of carotenoids affects the type of transport lipoprotein: carotenoids have low polarity, mainly transported by low-density lipoprotein (low-density lipoprotein,LDL) and enriched in LDL receptor-many tissues such as liver, testis and adrenal glands, while the higher polar luins are mainly transported by HDL and correspondingly enriched in tissues such as retina and nervous system.Differences in the polarity and positional distribution of carotenoids may also affect their functional performance
What effect does lutein have on plants of Natural Lutein Powder
Lutein has an important role on plant growth.
Chlorophyll can be used for photosynthesis to convert the sun’s photoenergy into chemical storage.Blue light in sunlight has a short wavelength, high energy, and a potential risk of damage to plant cells.While yellow is the blue complementary color, therefore, lutein can absorb and filter blue light, attenuate its damage to cells.
. Similar to plants, there is also one part of the human body containing plenty of lutein, which is the retina behind the eyeball.A yellow patch on the retina, known as macular plaque, containing large amounts of lutein and zeaxanthin, filters blue light from the light and reduces its damage to retinal pigment cells.However, you need to remind you that lutein cannot treat eye diseases, and you must seek medical treatment in time once you feel eye discomfort
Natural Lutein Powder Prevention of senile macular degeneration
In developed countries, senile macular degeneration (age.relatedmaculardegeneration,AMD) is the major cause of visual loss and blindness in older countries.In recent years, the incidence rate has also risen in developing countries.
Lutein as an important antioxidant present in the retinal macular region suggests that it plays a crucial role in maintaining eye health
Natural Lutein Powder can Prevent cataract
Cataract is a disease of visual impairment due to decreased lens transparency and opacity.Visual impairment in people over 60 accounts for about 50% of the total cataract visual impairment
No drugs have been found to restore the lens to transparency, and the only treatment is the surgical removal of the internal barrier
Lutein is one of the only two types of carotenoids in the human lens and is important for preventing cataract
Natural Lutein Powder can Prevent cancer
It has a role in preventing and inhibiting carcinogenesis.Some epidemiological investigations and experimental research results show that lutein, as an important carotenoid in the human blood, has a special biological function in inhibiting tumor growth.
The results of animal and cell culture studies showed that feeding foods with high lutein content inhibits apoptosis in breast cancer mice and enhances the proliferative effect of lymphocytes, thus prolonging the latency of tumors in mice
Natural Lutein Powder can Prevent cardiovascular disease
Cardiovascular disease is one of the main causes of death in humans, and its etiology is very complex.Yeltein may have a role in protecting the cardiovascular system.
The carbon chain of lutein molecule contains multiple conjugated double-bond structures. Because of its remarkable antioxidant properties, it plays important roles in maintaining the normal physiological function of the human body, and has the functions of preventing and inhibiting chronic diseases such as senile macular degeneration, cataracts, cancer and cardiovascular diseases
Application prospect of Natural Lutein Powder
Yeltein has bright yellow, insoluble in water, soluble in oil, ethanol, strong color force, with light resistance, heat, acid, alkali and other characteristics, can be widely used in food, health crystal, medicine crystal coloring.
Because lutein has a strong and stable coloring ability, especially for the various physiological effects of the human body are gradually paid attention to, the development and use of lutein will be very broad prospects. In China,
· Lutein is being widely used as a feed additive. Europe and the United States have used lutein as a food additive, giving food crystals a bright color
Natural Lutein Powder structure and physical and chemical properties
The unique chemical structure of lutein determines not only its color, but also its physicochemical properties.The lutein molecule has long ~ long strands of 40 carbon atoms with multiple conjugated double bonds that give lutein a distinct color and inhibitory radical capability.Yellowin
Natural Lutein Powder can protect your eyesight
Yeltein can absorb a large amount of blue light, the wavelength of blue visible light and ultraviolet light close, can achieve the visible light of the visible light of the retina, before reaching sensitive cells on the retina, the light first through the highest aggregation area of lutein, if the abundant chlorophyll content can reduce this damage.
Natural Lutein Powder Used in feed
One of the main uses of marigold lutein is as a poultry feed additive, commonly used as a coloring agent to animal feed, mainly used for laying hens and chicken feed, can improve the antioxidant of chicken fat in the process of refrigeration, lutein can improve the color of egg yolk and inhibit the oxidation of egg yolk lipid oxidation.
Source of lutein and Natural Lutein Powder
Mammal such as humans cannot synthesize lutein on their own and therefore must be obtained from food.Yeltein has a wide range of food sources and often exists in nature, which is the main component of plant pigments such as corn, vegetables, fruits and flowers.
Because its pure product is orange, we think that orange food content is rich, lutein is indeed in papaya, pumpkin, citrus, wolfberry, peaches and other orange fruits and vegetables, but the most abundant ingredients are in green leafy vegetables, such as kale, spinach, leek, cabbage, celery leaves, coriander, etc
The sources of lutein in animal foods are mainly milk and egg foods.Breast milk is the best source of lutein in infants, which is one of the important reasons for breastfeeding.Fresh milk and yogurt are all very good carriers of lutein.Although the content of eggs is not very high, but the bioavailability is good, almost three times the equal amount of vegetables.Lutein supplements can be used appropriately if found to lack lutein, or a lack of dark green leafy vegetables or orange fruits and vegetables for a long meal, or people using computers, mobile phones and TV for a long time.Yeltein has currently been listed as a dietary supplement.
LNatural Lutein Powder and visual protection
In the mid-20th century, lutein was discovered and recognized, initially recognized because it accumulated in the retina, helping to improve the density of macular pigment that can absorb harmful blue light and protect photoreceptors from damage, so an effective blue light filter was formed in the retina, which can reduce the oxidative damage caused by blue light.
Low macular pigment density is an important risk factor for the occurrence of retinal foveal degeneration, and lutein supplementation can significantly increase the pigment density in the retinal macular area, thereby changing visual function
Source and physicochemical properties of lutein and Natural Lutein Powder
Yeltein is the main component of the plant pigments such as corn, vegetables, fruits and flowers.Foreign studies have shown that lutein has the highest content in dark green cabbage, cabbage and spinach and marigold (also known as marigold), and its content in marigold flowers is as high as 1.6%
Currently, the commercialized lutein is mainly from marigold.Secondly, pumpkin, peaches, pepper, mango, citrus are rich in the “lutein ester”, namely the lutein precursor.Yeltein was first extracted from carrot roots by Heinrich in 1831.
Subsequently, Borzdllus extracted lutein from the autumn yellow leaves in 1837.Thereafter, Shi et al have extracted lutein in different kinds of algae, diatom, red algae, stone cauliflower and human grass
The physicochemical properties of lutein
Lutein (English habit name: Lutein), system name: 3,3 ′ primary hydroxyl ~ / 3, a one carotene, is a derivative of O/ one carotenoid
The lutein structure has a long chain containing 4O carbon atoms containing multiple conjugated double bonds, with strong reductivity, namely antioxidant activity.In terms of stability, lutein molecules are unstable to heat and UV because lutein molecules are highly unsaturated structures.
Lutein and age-related macular degeneration
Age-related macular degeneration is also known as senile macular degeneration, mostly originated around the age of 50, the older the higher the incidence, both eyes at the same time or successively injured, due to different clinical manifestations and divided into atrophy and exudation two types, atrophy is more common
Lutein and senile cataract
Elderly cataract is more seen over 40 years old, is an aging phenomenon, with the increase of age, crystal experience slowly hardening, turbidity and cause visual impairment.Early symptoms are fog vision, color change, immediate black spot, crystal myopia, diplopia, etc., to the advanced vision impairment 13 deep, and finally can only identify manual or only visual perception in front of the vision
In conclusion, lutein supplementation improves retinal macular pigment density, prevents visual degeneration and ocular physiological structural and functional variability, and plays an important role in preventing age-related eye diseases such as AMD and cataract.Therefore, lutein can be used in clinical practice as an adjuvant to the prevention and treatment of ophthalmic diseases.Since lutein cannot be synthesized for the human body itself and can only be taken from food, pay attention to often supplement lutein food, which is very important to prevent and control ophthalmic diseases such as AMD and cataract.
