The study on extracting protein from hazelnut kernel by aqueous enzymatic extraction method

摘要

The hazelnut in China northeast area was used as raw materials and Alcalase was employed to extract hazelnut protein in this study. The total hazelnut protein extraction rate was deemed as indicator and different factors were studied. The results showed that optimum conditions were: enzyme additive amount 2.0%, hydrolysis temperature 55°C, hydrolysis time 2.5h, the ratio of solid to liquid 1:5 and pH 8.9. The contribution rate of factors can be obtained by the F test is x_1>x_2>x_4>x_5>x_3, that is enzyme additive amount > hydrolysis temperature > the ratio of solid to liquid> pH > hydrolysis time.
