Study on the Construction of Luteolin Transport System Based on Zein and Sodium Alginate and Preservation on Fruit and Vegetable
In this study,zein and sodium alginate were used as raw materials to prepare luteolin loaded composite particle solution by antisolvent method,and its fresh-keeping effect on cherry tomatoes was evaluated.The results showed that when the ratio of luteolin to zein was 1∶50,the particle yield was 78.19%and the embedding rate was 73.87%.The results of antioxidant activity in vitro showed that compared with free luteolin,particle embedding could improve the antioxidant activity of luteolin.The results showed that compared with free luteolin,embedding could reduce the loss of water content,increase the content of vitamin C in tomato and slow down the loss of tomato hardness,indicating that particle embedding was beneficial to improve the preservation effect of luteolin.This study provides a new way for fruit and vegetable preservation and a new theoretical basis for the study of biological activity.
