| 摘 要： | 为了解决柿子酱热杀菌返涩问题,采用正交试验法确定了乙烯利脱除柿子涩味和超高压杀菌处理软包装柿子酱的最佳工艺条件。通过感官评价、耐藏性试验、微生物卫生指标检验、稳定性鉴定,研究了超高压处理柿子酱的安全、稳定性。结果表明:柿子用300 mg/L乙烯利溶液浸润10 s后于30℃密封脱涩5 d,柿子脱涩效果最好;脱涩后的柿子酱于25℃经400 MPa杀菌20 min,能明显延长柿子酱的货架期,有效地消除了脱涩柿子酱的返涩和变色现象。超高压非热杀菌技术能安全有效地防止脱涩柿子酱的返涩,延长柿子酱的货架寿命,保持柿子酱的原有色泽和组织结构。

| Abstract: | In order to solve the problem of the persimmon jam coming into astringent taste again during heat sterilization,the orthogonal experiment was used to optimize treating conditions of deastringent using ethephon solution and ultra-high pressure.The safety quality and the stabilization of persimmon jam produced by ultra-high pressure were evaluated using sensory appraising,conserving experimentation,microorganism sanitation index inspection and stability test.The results showed that after being dipped in 300 m... |
