Abstract
The invention relates to an elaeagnus mollis diels oil freeze-dried powder and a preparation method thereof; elaeagnus mollis diels oil obtained by carrying out a CO2 supercritical extraction technology or a squeezing method or a subcritical extraction technology on elaeagnus mollis diels seed kernels is used as a core material, an inclusion material and an emulsifier are added, the core material is embedded to form microcapsules, and the microcapsules are freeze-dried to obtain the elaeagnus mollis diels oil freeze-dried powder; according to the prepared elaeagnus mollis diels oil freeze-dried powder, materials are placed in a vacuum environment, ice in the materials are directly sublimated, the content of linoleic acid is ensured, and the elaeagnus mollis diels oil freeze-dried powder has excellent characteristics of excellent solid stability, dispersion, solubility and the like; the elaeagnus mollis diels oil freeze-dried powder can be used as a food nutrition additive to be added in preparation of cakes, drinks, nutritious diets and the like; the compounding of plant proteins and cyclodextrin not only retains the physiological activity of unsaturated fatty acids, but also increases the human body required nutrition proteins; and moreover, the food in a solid particle form also makes preservation and usage more convenient.
Description
Technical field
The present invention relates to field of food, be specifically related to a kind of samara oil freeze-dried powder and preparation method thereof.
Technical background
Samara oil is a kind of table oil having Development volue, its unsaturated fatty acid content is far above 90%, wherein oleic acid, linoleic acid plus linolenic acid are all essential fatty acids that body weight for humans is wanted, and then both can not be synthesized voluntarily by body, can only supply by food.Oleic acid can obvious elevating HDL-C, reduces LDL-C, promotes the eubolism of lipid; Linoleic acid plus linolenic acid can reduce serum cholesterol, triglycerides and LDL-C effectively, raise HDL-C, reduce blood viscosity simultaneously, prevent thrombosis, to the control of cardiovascular and cerebrovascular disease, particularly in disappear atherosclerotic and antithrombus formation, there is fabulous curative effect.So samara oil both can prevent cardiovascular and cerebrovascular diseases, can be used as again the functional grease that cardiovascular and cerebrovascular patient is desirable.
The unrighted acid of high level in samara oil, be highly advantageous to and reduce human serum cholesterol, but owing to containing one or more unsaturated double-bond in its molecular structure, so less stable, be placed in air or heating process is easily oxidized, is polymerized, grease after oxidation can produce bad flavor, and it is aging that the free radical being especially oxidized formation can accelerate human body cell.Current commercialized product is a kind of formulation of samara fat capsule only, not yet finds relevant report and the product of samara oil freeze-dried powder.
Summary of the invention
The object of the present invention is to provide a kind of water-soluble good samara oil freeze-dried powder and preparation method thereof, be intended to for people provide the instant food that a kind of unsaturated fatty acid content is higher.
For realizing above object, technical scheme selected by the present invention is: select high-quality to eat the parcel samara oil molecules such as inclusion material albumen powder, cyclodextrin, starch, cellulose and form micro-capsule, and by Freeze Drying Technique, the grease micro-capsule of liquid state is made pressed powder.This method is applicable to the grease to heat, oxygen sensitive type.
The present invention prepares the oily concrete scheme adopted of samara: adds suitable inclusion material and emulsifying agent for core, the microcapsules that core material is formed after embedding so that the samara that samara kind benevolence is obtained is oily, makes the oily freeze-dried powder of samara through freeze drying.
One or more in described inclusion material selection cyclodextrin (CYD), starch, cellulose and albumen powder.
The one in α-CYD, β-CYD, γ-CYD, glucityl-β-CYD, methyl-β-CYD selected by described cyclodextrin.
Described cellulose is as the one in methylcellulose, microcrystalline cellulose, sodium carboxymethylcellulose, hydroxypropyl methylcellulose, Ac-Di-Sol, HEMC, hydroxyethylcellulose, hydroxypropyl cellulose.
Described protein selects one or more in lactalbumin, soybean protein, collagen, rice protein and wheat gluten.
Described emulsifying agent selects that lauryl sodium sulfate, aliphatic acid sorb are smooth, one or more in polysorbate, poloxamer, Arabic gum, tragacanth and gelatin.
The preparation method of described samara oil freeze-dried powder mainly comprises following steps:
the samara oil choosing full seed, fresh samara kind benevolence obtained is core;
be 1:0.5 ~ 3 by cyclodextrin and albumen powder according to mass ratio, be made for the distilled water of 40 ~ 80 DEG C the wall material solution that mass concentration is 10% ~ 40%, and for subsequent use after carrying out ultrasonic pretreatment;
with samara oil for core, be core and the wall material of 1:1 ~ 3 by mass ratio, 2% ~ 8% mass ratio is that the smooth and compound emulsifying agent that is polysorbate of the aliphatic acid sorb of 1 ~ 5:10 ~ 5 adds in above-mentioned wall material solution, stand-by stir 20min under 500 ~ 1000r/min rotating speed after;
above-mentioned mixed liquor is added in high pressure homogenizer, at 30 ~ 50 DEG C, homogeneous 10min under 10 ~ 30MPa, forms samara fat liquor;
by samara fat liquor in-55 DEG C of pre-freezes, after pre-freeze 12h, be placed in vacuum freeze drier and carry out freeze drying; Initial freeze-dried material thickness about 1cm, condenser temperature is set as-40 DEG C ~-50 DEG C, maximum vacuum < 15Pa, and dividing plate final temperature is set as 40 ~ 60 DEG C, freeze-drying 10h ~ 24h.Vacuum freeze drying completes obtained samara oil freeze-dried powder.
Material is positioned over vacuum environment by the samara oil freeze-dried powder obtained by the present invention, the ice in material is directly distilled, ensure that wherein linoleic content, can add in the making of cake, beverage and nutrient diet etc. as nutrient additive for food.The compound use of vegetable protein and cyclodextrin had both remained the physiologically active of unrighted acid, turn increased needed by human body nutrient protein, and solid particulate form food also makes preservation and uses more convenient simultaneously.Prepared samara oil micro-capsule, not only can keep inherent characteristic and the function of samara oil, avoids the harm that illumination and oxidation are brought to human body, also has the good characteristics such as good solid-state stability, dispersiveness and dissolubility.
The invention has the beneficial effects as follows: production technology is simple, ensure that prepared samara oil freeze-dried powder nutritional labeling, expand the range of application of samara oil in food industry; Samara oil is after microencapsulation process, the samara of liquid state oil micro-capsule is made pressed powder, overcome the shortcoming of grease itself, become stable in properties, take conveniently, good fluidity and the high-quality edible raw material be of high nutritive value, larger Social benefit and economic benefit can be brought; Samara oil powdered adopts the more spray-dired advantage of Freeze Drying Technique to be, moisture in material directly distils, ensure that the nutritional labeling of material does not run off in preparation process, avoid high-temperature spray in spray-drying process to the destruction as heat-sensitive ingredients such as unrighted acids in active ingredient in samara oil simultaneously; Through contrast, samara oil freeze-dried powder comparatively spraying dry gained samara oil-bound distemper end solubility in water is higher, and the clarification of gained solution.
