綠甘藍(lán)超冰溫實(shí)體庫貯藏的最佳工藝參數(shù)及堆垛模擬研究

綠甘藍(lán)超冰溫實(shí)體庫貯藏的最佳工藝參數(shù)及堆垛模擬研究摘要：

為了探究綠甘藍(lán)超冰溫實(shí)體庫的最佳工藝參數(shù)以及堆垛存儲(chǔ)方式對(duì)其貯藏效果的影響，本文對(duì)不同貯藏溫度（0℃、-1℃、-2℃）下的綠甘藍(lán)超冰溫實(shí)體庫進(jìn)行了一系列研究。實(shí)驗(yàn)結(jié)果顯示，在適宜的貯藏溫度范圍內(nèi)，綠甘藍(lán)超冰溫實(shí)體庫的營(yíng)養(yǎng)成分變化較小，其貯藏時(shí)效性和質(zhì)量有所提高。最佳貯藏溫度為-1℃，相對(duì)濕度保持在95%以上。此外，堆垛模擬研究表明，綠甘藍(lán)超冰溫實(shí)體庫的最佳堆垛高度為5cm，堆垛寬度為5cm，堆垛后留有5cm寬的通風(fēng)縫隙。本研究結(jié)果能為綠甘藍(lán)超冰溫實(shí)體庫的存儲(chǔ)提供科學(xué)的依據(jù)，同時(shí)對(duì)該類蔬菜的保鮮、貯藏提供了一定的參考價(jià)值。
