Abstract
The invention discloses a kind of preparation methods of Tibet smooth pit peach Ultramicro-powder, comprising the following steps: Step 1: raw material pre-freeze to be processed to material center temperature is -2~-3 DEG C, obtains pre-freeze material；Step 2: pre-freeze material is 3%~6% through vacuum refrigeration to material moisture, dried material is obtained；Step 3: dried material grinding and sieving, obtains coarse powder broken material；Step 4: comminuting matter is placed in vibromill, regulation power is 1.0~1.4kW, and amplitude is 3~5mm, and temperature is 5~10 DEG C, crushes 10~30min, obtains ultramicro grinding material, pulverizes material and packs after sterilizing.The present invention has the beneficial effect for obtaining the Tibet smooth pit peach Ultramicro-powder that diameter of particle is small, particle size distribution span is narrow, the uniformity is high, dissolubility is good.
Description
Technical field
The present invention relates to fruit powder preparation fields.It is more particularly related to a kind of system of Tibet smooth pit peach Ultramicro-powder
Preparation Method.
Background technique
Tibet smooth pit peach category rosaceae peach category deciduous tree, is Tibet region one of wild fruit tree distributed more widely.Light core
Peach pericarp surface covers villus, and fruit stone surface is smooth, and fruit is subsphaeroidal, fresh food slightly bitter taste, rich in minerals, vitamin,
The nutriments such as dietary fiber, reduced sugar.At present about Tibet smooth pit peach utilization be concentrated mainly on fruit jelly, fruit wine, preserved fruit and
Fruit juice etc., but limited by factors such as traffic, information, environment and regions, cause Tibet smooth pit peach industrialization level non-
Often low, product cannot be introduced into mainland market.Fruit vegetable powder is low to ingredient requirement, and the scope of application is extremely wide, especially to the skin of edibility, core
It is available, and fruit vegetable powder is convenient, adjustability is strong, full of nutrition, can utmostly keep the original battalion of fruit and vegetable
It supports, flavor, is often used as ingredient and processes other food, become a kind of good nutrition deep processed product, further, fruit vegetable powder water
Point content is low, can suppress growth of microorganism and enzymatic activity, substantially reduces the expense of storage, transport, packaging etc., is conducive to
Promote the industrialization of Tibet smooth pit peach；
Ultramicro grinding is a kind of materiel machining technology for being the development of adaptation modern high technology and formation the 1970s.
It mainly overcomes solid interior cohesiveness to be allowed to broken using mechanical or hydrokinetic method, thus by the object of 3mm or more
Material particle is crushed to 10~25um subparticle below, and then product is made to have interfacial activity, shows specific function.Fruits and vegetables
