Description
Method For Preparing Enzymatic Modified Peanut Protein
This invention involves the preparing method of enzymatic modified peanut protein and it belongs to foodstuff protein processing filed.
Background technology
Peanut (ArachinConarachin L.),alternate name groundnut and long life nut, is not only oil crops but also protein crops. Its fat and protein contents are 43-55% and 25-30%, respectively.
Peanut protein contains eight kinds of essential amino acids and its biological value (BV) is more than soybeans, but its anti-nutritional factor is less than soybean’s. Therefore, peanut protein can be a new protein resource following soybean protein, thus solving a difficult problem of limited high quality protein in a world. However, some functional charactersof peanut protein isolate (PPI) produced by alkali extraction and acid sink technology and peanut protein concentrate (PPC)produced by ethanol extraction technology, such as solubility, emulsibility, emulsion stability, foaming characteristics and foam stability, are not suited to some food processingbecause of affecting by technological conditions. So applicationsof PPI and PPCare limited. This requires improving functional characters of peanut protein to meet the needs ofsome special food processing.
At present, there are four kinds of modification treatments for protein including physical modification, chemical modification, enzymatic modification and genetic engineering modification. Physical modification method contains thermal denaturation, squeezing, spinning and high static pressure. Physical modification method can improve some protein functional characters of foaming characteristics and emulsibility, but can do great damage to other functional characters of solubility and gelling. So physical modification methodis only suited to produce some special protein products. Chemical modification method contains phosphorous modification, succinylation, glycosylation, decarboxamidation, covalent cross-linking, hydrolysis, oxidize and some chemical modification proteins have been successfully investigated. However, there exist many problems of more reaction by-products, damaging protein amino acid composition and reducing nutritional value during chemical modification processing. Therefore, chemical modification method’s range of application is limited. Enzymatic modification method contains enzymatic catalysis and polymerization. There are many advantages in enzymatic modification method including the mild reaction conditions, non reaction by-products, high specificity. So enzymatic modification method is a safty modification method and it belongs to a emerging technology of enzyme engineering applying in food protein processing. The enzymatic ; modification method’sresearch and development has important significance and it has broad market prospects. Genetic engineering modification method is used to improve functional characters and nutrient composition of plant protein by genetic engineering in order to achieve the purpose of modification.
In order to develop and utilize peanut protein, this invention combines enzymatic modification method with microwave assisted enzymatic hydrolysis and ultrafiltration technology.
The enzymatic modification protein product can be produced with good solubility, foaming characteristics and foam stability based on the premise of less chemical reagent and short reaction time, The enzymatic modification method has the characteristics of mild conditions and low cost and is suitable for industrialized production.
