白鱼粉储存环境对其品质变化的影响
Effect of white fish meal storage environment on its quality changes
摘要
Abstract
The purpose of the study was to investigate the variation rules of white fish meal under different storage conditions.The moisture content,the freshness indexes(volatile basic nitrogen content,biogenic amine content,acid value and malondialdehyde content)and hygienic index(total mold count and salmonella)were monitored to investigate the quality change of white fish meal during storage under simulated cold storage(12,10,8℃,55%RH)and natural conventional storage(18~27℃,50%~70%RH)conditions,respectively.The results showed that the quality of the white fish meal stored under low-temperature environment and natural environment differed slightly.During the storage of the fish meal under natural environment for 253 d,the water content and water activity of the white fish meal increased.But the water content and water activity were less than 10%and 0.7,respectively.VBN,acid value,malondialdehyde and biogenic amines all changed slightly,thus the freshness of white fish meal had no significant change.The total number of molds was with in the limits of'Hygienical standard for feeds'(GB/T 13078-2017),and no Salmonella were detected.The study indicates that the key to ensuring the white fish meal quality during storage is to control the temperature(<27℃),relative humidity(<70%RH)and storage time(<6 months)and improve the air circulation.关键词
