Method for quickly preparing special gelatin for candies from raw bone meal

Abstract

The invention belongs to the field of gelatin preparation, and particularly relates to a method for quickly preparing special gelatin for candies from raw bone meal. The method comprises the following process steps of: meal milling, impurity removal through pickling, water washing, gelatin solution extraction, neutralization, rough filtration, fine filtration, and packaging after concentration and drying. According to the method, animal bones are milled into bone meal to increase the specific surface area of the bone meal and increase the reaction speed of the bone meal; and compared with thetraditional gelatin production, the method disclosed by the invention has the advantages that: the production cycle is shortened by more than 60 days, and pollution and consumption are reduced. The gelatin prepared by using the method has the advantages of high freezing intensity, moderate viscosity, good transparency and low cost; and the viscosity of the gelatin is matched with the freezing intensity of the gelatin, so that the gelatin is suitable for the field of producing foods such as candies and the like.

Description

1. Technical field: [0001] The invention belongs to the field of gelatin preparation, in particular to a method for rapidly preparing gelatin for candy from raw bone meal. 2. Background technology [0002] At present, the production of bone gelatin in my country all adopts the traditional alkaline process, and its process route is: animal bone → bone grains → pickling → water washing → liming → water washing → neutralization → water washing → gel extraction → filtration → concentration → drying → pulverization. Although the traditional gelatin has a history of hundreds of years and the technology is relatively mature, the production cycle is long, as long as 60 to 90 days, and the consumption of various materials is high, especially the waste of water resources. The traditional liming process uses milk of lime. A large amount of ash and waste water are produced every day, which belongs to high energy consumption and high pollution industries, and when its gelatin products ar...

Problems solved by technology

[0003] Aiming at the fact that there is no special gelatin specially used for the candy industry in the current gelatin production industry and other gelatins that cannot fully meet the requirements of the candy industry, that is, the problem that the viscosity of the gelatin does not match the freezing strength, the present invention proposes a kind of raw bone powder for rapid preparation of candy. The method for gelatin, the technical solution adopted by the present invention is: a method for quickly preparing gelatin for candy from raw bone meal, which is characterized in that it consists of the following steps: grinding animal bone powder → pickling to remove impurities → washing → extracting glue → Neutralization→coarse filtration→fine filtration→concentration and drying packaging; among them: the technological conditions of the animal bone grinding process are: grinding animal bones into 40-160 mesh raw bone powder; the technological conditions of the pickling and impurity removal process are: grinding The raw bone meal is soaked in the acid solution at a temperature of 15°C-25°C for 6-12 hours to remove impurities such as minerals in the raw bone meal. The pH value of the acid solution is 1-2.5, and the mass volume of the raw bone meal and acid solution The ratio is 1g:2-6ml; the process conditions of the washing process are: the raw bone meal soaked in acid solution is washed with water until the pH of the washing water is 4-6; the process conditions of the glue extraction process are: the washed bone meal Raw bone meal extracts the glue solution after 5 to 18 hours under lye at a temperature of 40°C to 70°C, the pH of the lye is 8 to 14, and the mass volume ratio of raw bone meal to lye is 1g:4 to 10ml; The process conditions of the neutralization process are: adjust the pH value of the extracted glue to 5.5-6.5 with acid; the process conditions of the coarse filtration process are: use a filter to filter the neutralized extract Filtration at low temperature to separate the gelatin liquid from the solid residue; the process conditions of the fine filtration process are: finely filter the gelatin liquid after the coarse filtration at a temperature of 40°C to 60°C; the process conditions of the concentrated drying and packaging process are: The fine filtrate is concentrated and dried by conventional methods
