Description
Technical field
The present invention relates to the production technology of alpha-linolenic acid, be specifically related to a kind of production method of alpha-linolenic acid microcapsule.
Background technology
Caulis et Folium Lini is a flax family (Linaceae) annual herb plant, is ancient phloem fiber crop and oil crop.Caulis et Folium Lini originates from Mediterranean, Near East bank, the distribution whole world, in the arid of NORTHWEST CHINA and North of North China, the plantation of semiarid extremely frigid zones at most, the extremely frigid zones performance optimal.
Semen Lini belongs to the seed of oil seed flax, oil seed flax seed oil content 35～42%.Being rich in unsaturated fatty acid in the oleum lini, is the current production rate maximum, ω-3 plant that content is the highest.
In threpsology's research, the field, forefront that paid close attention to by international nutritionist is the applied research about the serial unsaturated fatty acid of ω-3 at present.This is because the serial unsaturated fatty acid of ω-3 is to maintain the core living matter that human brain is evolved.Especially the parent alpha-linolenic acid of the serial unsaturated fatty acid of ω-3 is basic, the most primary material in the life evolutionary process.
Alpha-linolenic acid is the universally acknowledged essential fatty acid that can only lean on feed to replenish, and it can not synthesize at inside of human body, can only absorb from food.In recent years, along with people to the attention of health and the raising of quality of life, the research of alpha-linolenic acid and understanding are progressively deepened.Alpha-linolenic acid can be regulated immune system, has the function of blood fat reducing, blood viscosity lowering, and human early nutrition, baby's brain development, cardiovascular and cerebrovascular disease, malignant tumor inhibition, hyperlipidemia etc. are all had certain effect.
Alpha-linolenic acid is difficult to obtain from usual diet, need replenish human body by the mode of adding alpha-linolenic acid in food.But because alpha-linolenic acid itself is easy to oxidation deterioration, the shelf-life is short, is difficult to directly join in the food as a kind of nourishing additive agent, has limited the popularization and application of alpha-linolenic acid.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of alpha-linolenic acid microcapsule to overcome the shortcoming of the easy oxidation deterioration of liquid alpha-linolenic acid, prolongs its shelf-life and convenient transportation.
For reaching above-mentioned purpose, the production method of alpha-linolenic acid microcapsule provided by the invention may further comprise the steps:
1) after being sized mixing, ferment, zein starch makes the zein porous-starch;
2) with ethanol zein starch is mixed with 5～10% pure molten zein liquid, as the embedding medium of alpha-linolenic acid microcapsule;
3) the zein porous-starch is added in the cold pressing oleum lini, make the zein porous-starch fully adsorb the cold pressing oleum lini, make the zein porous-starch core of absorption cold pressing oleum lini;
4) the zein porous-starch core that will adsorb the cold pressing oleum lini adds in the rotation coating pan, and according to core: the weight ratio of embedding medium=1: 0.5～2 sprays into the pure molten zein liquid of embedding medium 5～10%;
5) rotation is stirred down, carries out drying in 60～80 ℃, obtains alpha-linolenic acid microcapsule.
Wherein, generally adopt the zein liquid of 80～90% alcoholic solution preparation embedding medium 5～10%.
The method production alpha-linolenic acid microcapsule that the present invention adopts zein porous-starch absorption cold pressing oleum lini and carries out embedding with the molten zein liquid of alcohol, zein porous-starch and pure molten zein liquid are natural food material, safe in utilization, stable in properties, abundant raw material.
The zein porous-starch has the ability of good adsorption liquid, but because the architectural characteristic of zein porous-starch, be adsorbed the hole that enters porous-starch when the cold pressing oleum lini after, still can ingress of air and oxidized at its hole opening part.In order to stop content to contact with oxygen, reach fully and the effect of air insulated, need to use softness good film material zein porous-starch granule to be wrapped up as the wall material.The present invention adopts 5～10% pure molten zein liquid as embedding medium (wall material) the zein porous-starch of absorption cold pressing oleum lini to be carried out coating, though its biological value is not high, but has the performance that some other protein can not be compared, the thin film that its forms is water insoluble, airtight, good barrier property, softness, intensity is higher, can under the human body intestinal canal environment, decompose, be absorbed by the body.
The wall material use quantity not sufficient, can make the particulate embedding of zein porous-starch incomplete, if but consumption is too many, not only the embedding efficiency increase is not remarkable, also can increase digesting and assimilating the time of human body.Through test, when the weight ratio of the zein porous-starch (core) of absorption cold pressing oleum lini and 5～10% pure molten zein liquid (wall material) was 1: 0.5～2, embedding efficiency was best.
Because pure molten zein is when independent film forming, the fragility of film is big, poor, the easy fracture of pliability.For the alpha-linolenic acid microcapsule that makes preparation has proper intensity and serviceability, need to add plasticizer and improve film forming tensile strength of institute and toughness.Plasticizer commonly used has glycerol, oleic acid and Polyethylene Glycol etc.Glycerol is as plasticizer, and its film forming transparency is better, and Polyethylene Glycol-400 and oleic acid all can improve the ductility and the pliability of film greatly.But take all factors into consideration oleic acid is one of edible main body of oil commonly used, so the present invention still adopts oleic acid as plasticizer.
The present invention has also investigated the influence of oleic addition to filming performance, and result of the test is: when oleic consumption be 5～10% pure molten zein liquid weight 1～6% the time, filming performance is best.
Behind zein porous-starch absorption cold pressing oleum lini, respectively disposable adding embedding medium and gradation adding two kinds of embedding medium addings of embedding medium mode are tested, the embedding efficiency that compares both, result of the test is as follows: the embedding rate that gradation adds embedding medium can reach 90～96%, and the embedding rate of disposable adding embedding medium has only 60～80%.As can be seen, adopt disposable adding embedding medium poorer than the embedding effect that gradation adds embedding medium.This is because employing gradation embedding mode can make thin film evenly, continuously, and surface area is big, and solvent evaporation is fast, to the little reason of content influence.
The present invention also compares the drying mode of alpha-linolenic acid microcapsule, when at 60～80 ℃ of employing hot air dryings, embedding rate can reach 90～96%, and adopt the embedding rate of direct drying to have only 70～80%, prove and adopt the embedding efficiency height of hot air drying than direct drying.This is to carry out drying because hot air drying is a particle surface at microcapsule, and it can make surface solvent volatilization and form thin film fast, and is little to the content influence.And heat is passed to granule interior during direct drying, because temperature is too high, has destroyed the structure of porous-starch, makes by the oils and fats of embedding and oozes out, so embedding rate reduces.
Zein starch and zein porous-starch that the present invention uses can be bought directly from the market, and reach biological engineering company limited etc. as Hebei China occasion starch sugar company limited, Wuxi star and all can produce.
The present invention adopts zein porous-starch and pure molten zein as the carrier and the embedding medium that prepare alpha-linolenic acid microcapsule, can make the liquid fat powdered effectively, avoid oils and fats to contact with air, slow down the oxidation deterioration of multiple unsaturated fatty acid in the oleum lini, can also seal the abnormal flavour that distributes in the oleum lini.
Production technology of the present invention is simple, and cost is low, invests for a short time, and the alpha-linolenic acid microcapsule product stock convenient transportation of producing is the perfect additive of food and health product.
