Study on High Efficiency Juice Processing Technology of Strawberry
The same batch of strawberries of the same quality were enzymolized with 8 different enzyme preparations using strawberries as raw materials,with the group without enzyme preparation as the control.The juice yield,soluble solids,pH value,total acids,total phenols,anthocyanins,and L*,a*,b*value of strawberries were measured.The principal component analysis method was used for multi-factor evaluation,and it was found that the juice extraction rate of RAPIDASE Fiber fruit pulp enzyme was as high as 92.57％,and the highest principal component comprehensive score of various indicators was 5.75697,indicating that the juice prepared by RAPIDASE Fiber had a higher juice yield and bright color,with the best overall effect.Single-factor experiments were conducted on enzyme addition amount,hydrolysis temperature and enzyme hydrolysis time,taking the above enzyme preparation as the object.Further optimization of enzymatic hydrolysis process parameters was carried out using response surface methodology,and the optimal parameters obtained were:enzyme addition of 412 mg/kg,enzymatic hydrolysis temperature of 52 ℃ and enzymatic hydrolysis time of 96 minutes.These process condition can achieve a strawberry juice yield of 95％and a* value of 15.08.
