Production method of active ginkgo nut milk powder

Abstract

The invention relates to a production method of active ginkgo nut milk powder. The production method comprises following steps: a, material preparation, wherein 100kg of fresh milk is heated to a temperature of 75 to 80 DEG C quickly, the temperature is maintained for 15min, the heated milk is delivered into an emulsification tank, an emulsification pump is turned on, 30kg of dried skim milk is added, the temperature is reduced to 40 DEG C, 14kg of ginkgo nut powder is added, and obtained mixture is mixed uniformly, and is subjected to emulsification for 30 to 40min; b, homogenizing, wherein the mixture obtained via step a is delivered into a homogenizer through a sterilized feed pump, and is subjected to homogenizing at a working pressure of 14 to 20Mpa; c, spray drying, wherein the temperature of the mixture at a material inlet ranges from 60 to 65 DEG C, and solid content ranges from 33 to 35%, moisture content of the mixture at a material outlet is less than 5%, inlet air temperature ranges from 170 to 180 DEG C, outlet air temperature ranges from 75 to 80 DEG C, the temperature of a drying chamber ranges from 70 to 90 DEG C, and powder recovery rate ranges from 96 to 98%; and d, powder discharging, cooling, and sieving, wherein milk powder obtained via spray drying is discharged, is cooled to a temperature below 30 DEG C quickly, is sieving using a mechanical vibration screen of 40-60 meshes so as to separate blocks, is stored for 12 to 24h, and then is packaged.

Description

Technical field [0001] The invention relates to a production technology of active ginkgo fruit milk powder. Background technique [0002] Ginkgo biloba is a rare and rare fruit that is unique to my country for medicinal and dietary purposes, and is favored by consumers. Ginkgo biloba in foreign countries is mainly used as a raw material for making cakes. Most domestic ginkgo is put on the market in the form of fresh fruit, and sales are restricted by the season. Part of the dried ginkgo powder is generally used as an auxiliary material for food processing companies and pharmaceutical companies because the color and fragrance of ginkgo are destroyed during the processing. There are solid beverages produced by using ginkgo spray-dried powder in China, but most of them are compounded with sweeteners, sour agents, etc., and their nutritional value and preparation properties are insufficient. [0003] Ginkgo biloba is an indispensable resource for the development of functional foods,...

AI Technical Summary

Problems solved by technology

[0003] Ginkgo is a rare resource for the development of functional foods, but the bioactive substances in ginkgo fruit are far less than ginkgo leaves, the protein content in ginkgo fruit is low, and the nutrition is unbalanced; the starch content in ginkgo fruit is high, and it can be used as a raw material for solid drinks , poor processing performance restricts the development of ginkgo products
