摘要: 韭黄是韭菜经过软化栽培的一种产品,但是易腐烂变质,本实验比较了三种蓄冷保温箱对韭黄的保鲜效果。以新鲜韭黄为试材,分别放入保温箱、组装箱和泡沫箱中,通过在箱中加入蓄冷剂,测定保温期间3种箱内外温湿度及韭黄品质的变化,比较3种蓄冷保温箱的保温能力和对韭黄的保鲜效果。结果表明,保温箱能有效保持箱内较低的温度和湿度,有效抑制了韭黄的失重、腐烂和转绿,保持了韭黄的抗坏血酸(V_C)和可溶性固形物(TSS)的含量,同时也保持韭黄良好的感官品质,相比较之下,保温箱可使韭黄的保鲜延长至4 d,组装箱内的保鲜可达3 d,泡沫箱内的保鲜仅为2 d,因此,保温箱具有较好的保温能力,能更好起到对韭黄的保鲜作用。Abstract: Hotbed chives is a kind of product that cultivated by leek softening, but it easy to rot and sicken. Three kinds of storage effect of cold insulation box of fresh chives were compared in this experiment.Using fresh chives as test materials, and they were put into the incubator, assembly box and foam box. By adding the coolant in the box, the temperature and humidity inside and outside of the 3 kind boxes and the quality changes of hotbed chives were determined, and the heat preservation ability of 3 kinds of cold storage thermal insulation box and the preservation effect of hotbed chives were compared.The results showed that the incubator could keep the lower temperature and humidity inside the box, effectively inhibited the weight loss, rot and turn green of hotbed chives, kept the content of VC and TSS in the hotbed chives, and kept good sensory quality of hotbed chives at the same time. In contrast, The heat insulation box can make the fresh of chives extended to 4d, assembled box preservation can reach 3 d, the foam box preservation was only 2 d, so, the incubator had a better insulation capacity than others.
