5.WLT——1500 Horzontal Spiral Immersion Scalding Device ： This machine is used together with large sized chicken and duck slaughtering line. It can be used for scalding .
7.The changes of POD(Peroxidase) activity at different scalding temperature and time,and the effects of scalding and freezing preservation on POD activity,amino acid,mineral elements,vitamins and amino acid nitrogen in Boletus aereus were studied.
8.The results show that the best scalding temperature is 95～96℃,its POD activity decrease 95.5% in 3 minutes. Scalding and freezing preservation had effect on nutritive value of Boletus aereus in varying degree.
9.Wistar rats inflicted by 40% TBS A of degree scalding were employed as scalding model. 2. Indices: The contents of ATP, ADP and AMP in the cultured cardiomyocytes were determined with HPLC and the energy load and ATP/ADP ratio were calculated.
10.The principle and function,method,and extent control of scalding and the two important factors which influence pre treatment effect,i. e,the temperature and the time of scalding,are researched. The proper technology of pre treatment for freeze drying vegetables is obtained.
