【中文摘要】 采用噴霧式流態(tài)化液氮速凍及緩凍,研究了在不同的凍結(jié)工藝條件下白靈菇的凍結(jié)溫度曲線及凍結(jié)速度與汁液流失率之間的關(guān)系等。結(jié)果表明對(duì)白靈菇進(jìn)行緩慢凍結(jié)時(shí),有明顯的凍結(jié)三階段現(xiàn)象出現(xiàn),而在液氮速凍時(shí)此三階段不明顯;建議采用-60℃以下溫度進(jìn)行凍結(jié),凍品在-26℃冰箱中貯藏9個(gè)月后,解凍時(shí)的汁液流失率低于4.9%。

【英文摘要】 Using slow freezing and liquid nitrogen quick freezer by the fashion of spray and flowed state,the Pleurotus ferulate varnebrodensis lenzi freezing technics was studied through analyzing the freezing curve at different temperature,freezing speed and rate of juice leakage.The results show that there are obvious three freezing stages by slow freezing,but the three freezing stages are not obvious by liquid nitrogen flash freezer.The author propose that freeze this mushrooms under-60℃,frozen food were stored 9 months at-26℃,its rate of juice leakage less than 4.9% after thawing.
