【摘要】:可裝卸式蓄冷保溫箱組裝、拆卸方便,是蓄冷保溫箱發(fā)展的趨勢(shì)。本文實(shí)驗(yàn)研究了平菇的冷鏈運(yùn)輸效果,測(cè)定箱內(nèi)空氣溫度、平菇中心溫度和蓄冷劑溫度變化,計(jì)算可裝卸蓄冷箱冷鏈運(yùn)輸過(guò)程縫隙漏熱率,每隔30 h對(duì)平菇取樣進(jìn)行感官評(píng)定,測(cè)定其營(yíng)養(yǎng)指標(biāo)變化。結(jié)果表明:當(dāng)環(huán)境溫度25℃時(shí),56 h后蓄冷劑完全液化,比預(yù)計(jì)時(shí)間少8 h,表明蓄冷劑需求量的估算值偏小,可以使用系數(shù)修正法予以調(diào)整;可裝卸式蓄冷保溫箱縫隙漏熱率達(dá)到12.97%,縫隙漏熱量占比大,應(yīng)優(yōu)化組裝工藝;實(shí)驗(yàn)60 h與0 h相比,感官評(píng)分下降3.53%,可溶性固形物含量下降5.9%;可溶性蛋白質(zhì)含量下降4.2%;維生素C含量下降9.96%,實(shí)驗(yàn)過(guò)程平菇商品價(jià)值、營(yíng)養(yǎng)價(jià)值變化不大。
[Abstract]:Assemblage and disassembly of stevedoable storage heat preservation box is the development trend of storage heat preservation box. In this paper, the effect of cold chain transportation of Pleurotus ostreatus was studied experimentally, the air temperature in the box, the center temperature of Pleurotus ostreatus and the temperature of cold storage agent were measured. The heat leakage rate of the gap in the cold chain transport process was calculated, and the sensory evaluation of Pleurotus ostreatus was carried out every 30 hours. The nutritional indexes were measured. The results show that when the ambient temperature is 25 鈩,
