Description

The preparation method of natural mulberry powder

Technical field

The present invention relates to the sorosis processing technique field, be specifically related to a kind of preparation method of natural mulberry powder.

Background technology

It is a kind of brand-new processing mode that occurred in recent years that fresh fruit of vegetables is processed into the fruits and vegetables powder.Because it has characteristics such as easy preservation, instant, of many uses and adjustability are strong, the advantage in garden stuff processing is apparent.At present, the production of fruits and vegetables powder is at the early-stage in China, and the fruit variety that is suitable for processing is few, and the fruit powder is of less types, the general fruit juice processing of adopting more.But owing to fruit juice sugar, pectin content height, generally be difficult to drying, at present, methods such as multipurpose spraying drying, microwave drying, explosion puffing drying, heated-air drying are produced the fruit powder.But generally all there are raw material availability low, difficult dry, speed slow (sugar, pectin content height with these method product processed, viscosity is big, so be difficult for dry, speed is slow), easily caking, rehydration is poor, color, smell and taste change greatly, shortcoming such as more than the nutritive loss, sometimes also needing to add other additive could be fully dry, thereby influence the purity of product, these disadvantages affect the fruit powder be used for secondary operations and direct edible characteristic as food auxiliary material or additive, restricted really market and the development space of powder.

Sorosis claims mulberries again, and its nutrition is very abundant, contain glucose, mineral matter, vitamin and each seed amino acid, highly beneficial to health, be one of " integration of drinking and medicinal herbs " fruit of Ministry of Public Health's approval, have the good reputation of " China fruit king " " human body blood bank " " holy fruit among the people ".

At present, because the seasonality of sorosis is very strong, be difficult to preserve, how to eat raw, in order to prolong the open date of sorosis, solve seasonal problem, occurred cloudy mulberry juice and the common mulberry wine product of many routines now on the market.But there is raw material availability low (remove the peel, remove slag, nutrient loss) in these existing products, store and carry inconvenience, and product specification is not high, added value is low, fails really to embody shortcomings such as the due commercial value of sorosis.

Summary of the invention

The present invention is directed to the above-mentioned deficiency of prior art, provide a kind of raw material availability height, form exquisiteness, color, smell and taste good, bright in colour, nutritive loss is few, rehydration good, store easily, be convenient for carrying, and have more the preparation method of natural mulberry powder of the natural attribute of product itself.

In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of preparation method of natural mulberry powder, and preparation process comprises:

(1) raw material is checked and accepted;

(2) remove the base of a fruit: remove the base of fruit of sorosis bottom, reduce bitter taste.

(3) clean, select: with circulating water silt that flush away is with and foreign material; Reject to go rotten, crude fruit and branches and leaves; (4) fragmentation: the sorosis after selecting carries out fragmentation through disintegrating machine and obtains the fruit piece;

(5) defibrination: with the levigate pulp that obtains of step (4) fruit piece;

(6) homogeneous: the pulp after step (5) is levigate carries out homogeneous, and the pressure of homogenizing process is 20 ~ 25Mpa;

(7) filter: filter with the pulp of screen pack after to step (6) homogeneous, to remove impurity and fruit piece (the recyclable recycling of fruit piece);

(8) freeze-drying: divide two stages: pre-freeze stage control material thickness 8 ~ 10mm, temperature-35 ~-45 ℃, 1.5 ~ 2 hours time; Sublimation stage control material thickness 8 ~ 10mm, hothouse pressure 80 ~ 90Pa, 60 ~ 75 ℃ of temperature of heating plate, obtain the fruit powder (freeze-drying is to be frozen into liquid solid-state at low temperatures earlier with interior 5% to material moisture control, under vacuum, directly heat then and freeze the solid material of attitude, make its distillation and drying);

(9) pulverize: the fruit powder after step (8) freeze-drying is carried out the Powdered fruit powder that dispersion and fining obtains the quality homogeneous.

The preparation method of sorosis powder of the present invention, preparation process also comprise the following steps after the pulverizing:

(10) packing, finished product: the fruit powder after the refinement is in time carried out package encapsulation, and warehouse-in is preserved.

Raw material in the step of the present invention (1) is that the smell of fruits is very sweet, beautiful in colour, " big ten " kind that utilization rate is high.

Step of the present invention (4) fragmentation obtains the sorosis fruit piece into former sorosis length 1/3 ~ 1/5.

Step of the present invention (7) screen pack is 120 eye mesh screens.

Advantage of the present invention and beneficial effect:

1. the sorosis that the present invention is directed to " big ten " kind is rich in sugar, whole characteristics edible, beautiful in colour, earlier with after the refinement of the whole fruit of sorosis, adopt vacuum freeze-drying method, in conjunction with technology such as homogeneous, ultramicro grinding processing sorosis powder, product not only raw material availability height, form exquisiteness, color, smell and taste is good, bright in colour, rehydration is good, and have more the natural attribute of sorosis product, also solved simultaneously the rate of drying that exists in the general fruit powder processing slow, be difficult for existing in dry technical barrier and the product as nutrient loss seriously, the shortcoming of rehydration difference.Therefore, sorosis is processed into powder has not only enriched product variety, and for food processing provides good natural auxiliary material and additive, have very vast market prospect.

2. do not add any chemical reagent in the sorosis powder of the present invention, more natural, purity is high, therefore, is the pollution-free food of health environment-friendly.
