Abstract

The invention belongs to the technical field of fruit processing, and in particular relates to a method for processing fresh jujube fruit powder. In the prior art, the flavor and nutritional ingredients of the jujube powder are different from those of the fresh jujube. In order to overcome the problems of the prior art, the technical scheme adopted by the invention is as follows: the method for processing the fresh jujube fruit powder is characterized in that selected jujubes are cleaned by clean water, and impurities and bad fruits are removed. The method comprises the following specific steps: 1) separating skin from flesh; 2) separating kernels from flesh; 3) grinding accurately; 4) carrying out spray drying; 5) adding tapioca flour which accounts for 20% of the total weight of jujube powder, and mixing; and 6) packaging: packaging the dried jujube flesh powder to obtain jujube flesh powder products after drying fully. The method provided by the invention is perfect in process flow; and the prepared fruit powder is complete in nutrition and good in instant solubility, and has the faint scent and original taste of fresh jujubes.

Description

A kind of bright jujube fruit powder processing method
Technical field
The invention belongs to the processing fruits technical field, be specifically related to a kind of bright jujube fruit powder processing method.
Background technology
Red date is the ancient and traditional fruit of China; Cultivation history with several thousand; But the red date original product that remains that people can have is at present perhaps dried the jujube powder product that grinds with the jujube juice that dried jujube is leached into, and directly is processed into the jujube powder or the market vacancy by bright jujube.Large-scale development along with the cultivation of China recent years red date; Red date output improve year by year and the people to the higher demand of red date product; The red date deep processing has begun to come into one's own; Had a plurality of enterprise production to go out the jujube powder of producing through drying technology on a small quantity in market, but its taste and nutritional labeling thereof and bright jujube relatively reduce a lot, so by the bright jujube inexorable trend that directly to be processed into bright jujube powder be red date deep processing from now on by system extra dry red wine jujube.
Summary of the invention
The object of the present invention is to provide a kind of bright jujube fruit powder processing method, compared the problem that has a long way to go with bright jujube with the jujube powder taste and the nutritional labeling thereof that overcome the dried jujube production of prior art.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of bright jujube fruit powder processing method cleans the red date of choosing, remove impurity and decayed fruit with clear water, it is characterized in that concrete preparation process is following:
1, skin and flesh separates: separate with pulp with the skin of self-control special equipment with fresh jujube fruit;
2, nuclear meat separates: with the self-control special equipment bright jujube meat is separated with jujube nuclear;
3, correct grinding: the bright jujube meat after the stoning peeling is directly ground to form turbid juice, promptly with the jujube juice of jujube meat,
4, spray-drying: after will grinding, fineness reaches the jujube juice process spray drying treatment of the band jujube meat of standard, becomes dry jujube powder; The sprayer that spray-drying is used is selected centrifugal sprayer for use, and main part is the disk that tangential vane is arranged that rotates at a high speed, and its rotating speed is: 3000~50000r/min; Feed liquid is sent into disc centre, under the centrifugal inertial force effect, dished out, form droplet; During spray-drying; About about 100 microns of atomized drop diameter, the hot-air inlets temperature is 150~250 degrees centigrade, outlet hydrofuge temperature is 80~95 degrees centigrade.
5, the tapioca starch that adds jujube powder gross weight 20% mixes;
6, packing: fully after the drying, the jujube digested tankage packing of drying is become jujube digested tankage product.
The present invention is with respect to prior art, and its advantage is following:
1, need not make dried powder process again, guarantee bright jujube nutritional labeling maximization;
2, production process does not need high temperature, under the normal temperature about 10 degree, gets final product, and has avoided the nutrient loss that high temperature causes and the change of bright jujube fragrance;
3, mix 20% tapioca starch to reach instant effect;
4, with self-control peeling stoning machinery, avoid peeling with chemical agent.
5, this method can well keep multiple nutritional components such as the Vc of red date, total phenol, and the intrinsic characteristic fragrance of reservation itself, and technological process is perfect, the delicate fragrance original flavor of producing that the nutrition of fruit powder is complete, instant capacity good, taste has bright jujube.
The specific embodiment
Below in conjunction with the specific embodiment the present invention is elaborated.
A kind of bright jujube fruit powder processing method cleans, removes impurity and decayed fruit with the red date of choosing with clear water, and concrete preparation process is following:
1, skin and flesh separates: separate with pulp with the skin of self-control special equipment with fresh jujube fruit;
2, nuclear meat separates: with the self-control special equipment bright jujube meat is separated with jujube nuclear;
3, correct grinding: the bright jujube meat after the stoning peeling is directly ground to form turbid juice, promptly with the jujube juice of jujube meat,
4, spray-drying: after will grinding, fineness reaches the jujube juice process spray drying treatment of the band jujube meat of standard, becomes dry jujube powder; The sprayer that spray-drying is used is selected centrifugal sprayer for use, and main part is the disk that tangential vane is arranged that rotates at a high speed, and its rotating speed is: 3000~50000r/min; Feed liquid is sent into disc centre, under the centrifugal inertial force effect, dished out, form droplet; During spray-drying; About about 100 microns of atomized drop diameter, the hot-air inlets temperature is 150~250 degrees centigrade, outlet hydrofuge temperature is 80~95 degrees centigrade.
5, the tapioca starch that adds jujube powder gross weight 20% mixes;
6, packing: fully after the drying, jujube digested tankage packing is become jujube digested tankage product.
Fresh red jujube powder by above method makes is following through the parameter that test detects:
Use fresh red jujube 100kg, pulp 46kg is arranged, sugar content (Brix) after the peeling stoning: 13, bright jujube juice Vc content: 91.9mg/100g.
Each index parameter of jujube powder:
