A kind of sunflower seeds nutrient blend oil microcapsules and preparation method thereof suitable for infant
Technical field
The present invention relates to food processing technology fields, and in particular to a kind of sunflower seeds nutrient blend oil suitable for infant
Microcapsules and preparation method thereof.
Background technique
Infant period is people's growth and development most important period and most critical period of intellectual development in life, baby
The growth and development in child's period is the significant process of Body organs growth and function maturation.Breast milk is infant food
Most ideal source includes required various nutritional ingredients in infants growth and development.Fat content in breast milk is about 3.6%~
4.2%, it is the important nutrient in breast milk.Take the photograph people's amount and the Fatty acid compositions of infant period fat send out the growth of baby
It educates most important.In breast milk fat can not only provide energy needed for baby 45.0% (0~6 month) and 30.0%~
40.0% (7~12 months), and essential fatty acid required for growth and development, especially linoleic acid and flax are provided for baby
Acid, it is extremely important for the brain function and visual acuity of baby.Therefore, the intake of scientific dietary fatty acid is raw to infant's individual
Long development plays an important role, on the contrary, will increase the diseases such as infant's heart disease, coronary heart disease, diabetes if blindly taking in fatty acid
The occurrence probability of disease, while causing infant's problem of obesity, infant's normal growth and development is damaged, each function of its body is influenced
Normal effect, to infant, health problem can generate many adverse effects in the future.Earlier part infant can be obtained by breast milk
Enough to it is adipose-derived, but for can not carry out breast-feeding or wean after infant, if it is possible to select suitable food
It with grease, grows up healthy and sound for them of great advantage, in recent years, with China's expanding economy, the dietary fat of China resident
Intake and composition ratio also have large change, how to select the edible oil of safety, nutrition, take the photograph infant pregnant and lying-in women reasonably
Enter fatty acid, meet the nutritional need of infant growth, becomes particularly important.Since the problem of oxidation of grease is food work
The critical issue of product quality is influenced in industry, the oxidation of fatty acid directly results in the decline of baby formula product quality, to baby
The growth and development of child will generate serious harm.And microencapsulation nutritional oil, so that fatty acid and air insulated, it is ensured that
The nutritional quality and edible safety of baby formula product.
Sunflower seeds is a kind of important oil crops, and most wide one of the oil crops of cultivated area in the world, certain herbaceous plants with big flowersization
Contain 47%~65% grease in seed benevolence, unsaturated fatty acid accounts for 70% of fatty acid or more, the linoleic plus oleic acid of high-content
Make sunflower oil that there is the ability more than other plant oil dissolving cholesterol, advantageously reduces cardiovascular disease and hyperlipidemic conditions
Generation.Furthermore sunflower oil is also rich in the nutriments such as vitamin E, carrotene and magnesium, phosphorus, sodium, calcium, iron, potassium, zinc,
It is known as the title of health-care edible oil.Research points out that often edible sunflower oil can protect skin health, enhances human immune system
Function improves cardiovascular and cerebrovascular disease, the generation of the diseases such as prevention.The consumption figure of sunflower oil in the international market occupies
World forefront, wherein the consumption proportion of Japan, South Korea is up to 70%.The annual consumption of China's sunflower oil had reached 80 in recent years
~90 ten thousand t.Linseed is also known as flaxseed, and linseed oil is also known as linseed oil, and unsaturated fatty acid content is up in linseed oil
90% or more, wherein the alpha-linolenic acid with plurality of health care functions, is 50%~60% according to different sources content, and rich in the wooden phenol
Element, flavones isoreactivity substance, and it is very high containing vitamin E and mineral matter element abundant, especially potassium content, it is high potassium food
Object.Potassium content than orange, shelled peanut, dried shrimp is higher by less than many and other many edible vegetable oil and fats.The U.S.
FDA research has shown that: shortage alpha-linolenic acid will lead to children's brain and retinal development is slow, absent minded, and nutrition is uneven
Weighing apparatus, can not effectively absorb nutriment, and it is slow to directly result in infant intelligent development, exercise not harmony, eyesight is weak, it is more it is dynamic,
More than 30 kinds of symptoms and the diseases such as fat, development slow, anorexia, hypoimmunity.Olive oil is with the fruit of olive (fresh fruit)
For raw material, the oil and fat product extracted using cold squeezing process, not heated and chemical treatment remains natural nutrient component, by
In olive oil rich in nutrition content, healthcare function is prominent and is acknowledged as green health edible oil, has prevention cardiovascular and cerebrovascular disease
The functions such as disease, diabetes, anti-cancer, anti-aging have the laudatory title of " vegetable oil queen " " liquid golden " in west.Walnut kernel contains rich
Rich protein, phosphatide, multivitamin and quantity is sufficient, ratio is suitable linoleic acid, linolenic acid, have " black hair, beauty treatment,
Brain tonic, salubrity " effect is that the traditional doctor in China eats dual-purpose good merchantable brand, enjoys the beauty of " intelligent promoting fruit ", " Longevity ", " treasured for supporting people "
Claim.The fat content of walnut kernel is up to 60~70%.There is the most nutrition and health care of walnut kernel by the walnut oil that walnut kernel refines
And pharmacological effect ingredient, containing various bioactivators, in addition to containing more linoleic acid, alpha-linolenic acid and vitamin E,
It is micro- also containing lot of trace functional components such as nervonic acid, gadoleic acid, EPA, DHA, squalene, epiphysin, flavones, carrotene
Amount functional component is the important component of walnut oil alimentary health-care function.DHA is the more insatiable hungers of docosahexaenoic acid n-3 system
And fatty acid, be a kind of long-chain polyunsaturated fatty acid with critical function in brain and retina, in infant's vision and
It plays a significant role in neurodevelopment.DHA can reinforce infant brain cell development.DHA is to infant's central nervous system
Physiological action is even more important, because DHA is the important composition ingredient of brain tissue and retina, can promote infant's brain and eyesight
Normal development.If infant lacks DHA, nerve fibre and neural junction development outstanding on the one hand can be influenced, baby is caused
Child's attention is impaired, and obstacle occurs in cognitive ability;On the other hand it can lead to eyesight abnormality, light-dark discrimination ability reduced,
It is fuzzy to see thing, therefore the addition of DHA algal oil is particularly significant.
Microcapsules technology refers to using solid fine particle, liquid droplet or gas as the core material of microcapsules, outside it
Face compounds the encapsulation techniques of formed continuous film using one or more substances.It, can by infant using microencapsulation technology
Edible albumen and carbohydrate gets up oxidizable rotten vegetable oil embedding as wall material, can allow unsaturated fatty acid and outer
The environment on boundary separates, and avoids contacting the oxidation so as to cause functional fatty acid with air, delays its oxidative rancidity.Microcapsules
Powdered oil after change not only overcomes a variety of disadvantages of conventional grease, have more instant into water, stability is high, be readily transported,
The advantages that production, preservation, the use scope of grease is greatly widened.The nutritional oil of microencapsulation can be answered as food ingredient
For infant's dairy products, rice flour, rice paste and other infant's products.
Summary of the invention
Shortcoming present in view of the above technology, the present invention provides a kind of fatty acid composition rationally, process safety,
