EFFECT OF HOT RINSING ON QUALITY OF QUICK FROZEN CHINESE TOON BUD

摘要

It was conducted on effects of hot rinsing, different kind of hot rinsing processes on nutrient components and quality of Chinese toon bud (CTB)after it was frozen quickly. These results indicated that the peroxidase(POD)activity of CTB was inhibited markedly by hot rinsing and quite good nutrient and appearance quality were maintained. After storage for 30d the content of Vc, water, protein and chlorophyll of forzen Chinese toon bud (FCTB) treated with hot rinsing was 12. 10 times, 6. 14% ,6. 14% ,26. 00% ,30. 00% higher than that of FCTB treated with without hot rinsing respectively, while the crude fiber content of the former was 18. 80% lower than that of the latter. The best quick freezing and process condition for CTB was hot rinsing 0. 5min with water.
