范文编号:SP113 范文字数:13130,页数:31 摘 要:本范文是研究AD万年青罐头加工技术,以AD万年青为原料,开展AD万年青的护色试剂研究。万年青是一种经过脱水(干燥)处理后的特色蔬菜。蔬菜脱水除了可基本保持其原有品味外,还有许多特点。万年青季节性短,严重制约其发展,目前在浙江主要加工成干燥的产品,产品单一,不利于销售。在实验中主要是先研究海藻糖对万年青罐头的护色效果,再分别用Zncl2,Cacl2等和海藻糖混合对万年青罐头进行护色研究,进一步寻找适合万年青罐头护色的试剂组合。最后实验得出了海藻糖对万年青有很好得护色效果,万年青在0.6%海藻糖和0.5%氯化钙组合护色剂中浸泡时间60min时护色效果最好。本实验还研究了杀菌温度和时间对万年青色泽,品质和贮藏中为微生物的的影响,通过叶绿素测定、感官测定和和微生物检测结果,从而得到了最佳杀菌条件(杀菌温度85℃,杀菌时间20min)。 Abstract: This article study of AD Rhodea Roth processing techniques to AD Rhodea Roth for raw materials,develop the research of color reagents to AD Rhodea Roth . Rhodea Roth is a dehydrating (dry) handling of a feature vegetables. Dehydrated vegetables in addition to the basic kept its original taste, there are have many features. It seasonal short, seriously hampering their development. Currently in Zhejiang mainly processed into dry products, a single product, not to sell the product. In the experiment is the first major study of the trehalose color effects to Rhodea Roth canned, and then using Zncl2, Cacl2 and other mixed with trehalose to studies the color effect for Rhodea Rothcanned , Further look for the suitable of color composite reagent for Rhodea Roth canned .Experimental reached find that trehalose have a good color effects to Rhodea Roth, Rhodea Roth at 0.6% trehalose and 0.5% calcium chloride color combinations agent soaking the time of 60 minutes when have the best color effective .This study also Research the impact of sterilizing temperature and time on Rhodea Roth color, quality and storage of microorganisms. Though the test results of that the Determination of chlorophyll , sensory and microorganisms,hence the best sterilization conditions(85 ℃of Sterilizing temperature and 20min for Sterilization time). 关键词:海藻糖浓度;浸泡时间;杀菌温度;杀菌时间;微生物检测 AD万年青罐头加工技术研究相关范文 |
