摘要:

以青浦农场的草莓为对象,研究其冰点和部分理化性质。经测定,草莓的冰点为-0.8℃,因此实验设计草莓贮藏温度为(0.0±0.8)、(4.0±0.6)、(20.0±0.5)℃,并分别在不同贮藏时间测定3个温度条件下草莓的质构、VC含量、可滴定酸含量、颜色变化,并进行感官评价。结果表明:在20℃条件下贮藏的草莓约3d后已经不能为消费者所接受,另外2个温度条件下的草莓货架期约为15d,且感官评分、质构参数、颜色变化、质量损失率均没有显著差异(p>0.05)。鉴于普通家用冰箱有一定的温度波动,推荐4℃为青浦农场草莓的适宜贮藏温度。

Abstract:

Strawberries from Qingpu farm were chosen as samples to investigate their freezing point and physico-chemical
properties. For this purpose, three different storage temperatures, (0.0 ± 0.8), (4.0 ± 0.6) ℃ and (20.0 ± 0.5) ℃ were set
and texture properties, VC and titratable acid contents, color parameters and sensory quality of strawberries were determined
at different periods of storage. The results indicated that strawberry fruits stored at 20 ℃ were unacceptable after 3 days
of storage, but the shelf life of strawberry fruits at the other two temperatures were close to 15 days, without significant
differences in sensory evaluation, texture parameters, color change or weight loss rate (p > 0.05). As for temperature
fluctuation in a common domestic refrigerator, 4 ℃ is recommended for the storage of strawberry furits from Qingpu farm.
