Effect of production auxiliary materials of infant rice formula powder on enzymolysis processing

In order to realize the effect of production auxiliary materials of infant rice formula powder on enzymolysis processing,the effect of additive amount of sucrose,glucose,fructose,milk powder,isolated soybean protein,whey protein concentrate and slurry concentration on enzymolysis of rice starch were studied.The results showed that carbohydrates had a greater impact on enzymolysis of rice starch than proteins,and glucose showed the greatest inhibition of enzymolysis among them,and the degree of hydrolysis reduced by 87.8% when glucose content reached 20.0%.Milk powder,whey protein concentrate and isolated soybean protein had a less influence on enzymolysis. Enzymatic reaction was inhibited by increasing slurry concentration,compared to the slurry concentration of 30.0%,the degree of hydrolysis reduced by 77.0% when the slurry concentration was 45.0%.Finally,a set of new enzymatic process was summarized on the basis of effect of production auxiliary materials on enzymatic reaction.
