Description
Technical field
The invention belongs to food processing technology field, the extruding paddy in liquid particles mixing sterilised products is related in particular to
Composition granule, also relates to the preparation method of the extruding cereal-granules in liquid particles mixing sterilised products.
Background technology
In recent years, liquid particles product is having become the main development direction of dairy products, beverage industry, China market
Upper existing a variety of liquid form products containing particle, " grain is more " of such as Erie, the growth as dairy products, beverage industry newly
Point.
Cereal includes Cereal, beans and potato class, is main, the most economical heat energy source of human body.Cereal is rich in compound
Carbohydrate, can provide " plain energy ", be conducive to nutrition balanced and digestive utilization ratio is high.Cereal contains abundant cellulose,
Be conducive to improving function of intestinal canal, reduce blood cholesterol level, there is prevention effect to angiocardiopathy and diabetes.In addition,
Cereal also provides the multiple elements such as vegetable protein, magnesium, potassium, phosphorus, iron and vitamin E and B family vitamin etc..Needed by human body heat energy is about
There is 80%, protein to there are about 50% all to be provided by cereal.Therefore, state food health plan（PNNS）Strong suggestion people food
Use cereal.
Existing cereal-granules/emulation grain is a kind of convenient instant food, is eaten in short-term after rehydration.General brewed in hot water 3-
8min can rehydration completely, reach it is edible needed for mouthfeel.Restructuring coarse cereals rice can eat by general rice, boil rear mouthfeel and
Rice is identical.But above-mentioned particle is not resistant to the long-time immersion in process for sterilizing in heat intensive and accumulating, can directly lead
Cause particles swell too much even completely defeated and dispersed, lose due shape and mouthfeel.
At present, cereal beverage is affected by the welcome of consumer, and the cereal beverage such as based on corn, oat obtains fast
Speed development, it is natural that cereal-granules are added wherein.And in other beverage made of fruits or vegetables, there is also reality for addition cereal-granules
The technology on border needs.
Milk is one of most ancient natural drink.Contain abundant protein, predominantly casein, white egg in milk
In vain, globulin, lactoprotein etc., and essential amino acid A wide selection of colours and designs contained by milk proem matter, quantity are sufficient, and ratio is appropriate, belongs to
Complete protein, human consumption leads up to 98%.In addition, the content of the calcium, phosphorus, iron, zinc, copper, manganese in milk is all a lot, and
Calcium phosphorus ration is appropriate, is the best source of human calcium beneficial to the absorption of calcium.Because milk is nutritious and easily digests and assimilates,
It is described as " white blood ".Currently, the method for disinfection used during milk working process is with ultra high temperature short time sterilization（UHT）Method with
Based on pasteurization.
To improve the comprehensive utilization value of cereal and milk, cereal-granules can be added to production liquid particles in milk and mixed
Close UHT milk --- UHT particle milk.Amino acid, vitamin type and quantity so in food need closer to Human Physiology, battalion
Support more balanced.Chinese residents have the custom of food grain congee, naturally enough wish the quality of lifting congee and are packed
City meets such market demand to eat, just.Therefore, novel particle dairy products is either still developed from nutrition

25s）；2nd, the cereal after sterilizing within a package can undergo in transporting procedures to be soaked for a long time.Excessively gelatinization causes UHT particles
Milk is when edible, and usually parectasis is even defeated and dispersed for cereal-granules, and in the pasty state, chewiness is partly or entirely lost, and loses and disappears
The mouthfeel of cereal in similar " congee " that expense person is liked.To avoid high temperature sterilization, immersion for a long time from causing cereal to be excessively gelatinized simultaneously
Promote beneficial flavor formation, some processes can be before cereal-granules be added by its high temperature frying.
Secondly, UHT sterilization machines have strict demand to granular size, it usually needs control is directly resulted in big in 4-6 mm
Part natural grain can not be used, and raw material type is limited.If by natural grain be crushed to it is appropriately sized after be directly appended to liquid
Sterilized in feed liquid, although meet the requirement of process for sterilizing, but cause excessively gelatinization aggravation because destroying the natural structure of cereal.
Again, even same source, with a batch of natural grain, there is also size, shape, integrality, inherent quality
The differences such as quality, it is difficult to ensure uniformity, cause product quality uneven.In addition, adding natural grain in UHT milk
Grain, it is impossible to freely add other food ingredients, it is difficult to carry out nutrition compounding and reinforcing, the category for limiting product is expanded.
