Abstract

The Lanzhou bulb of lily has gained global attention due to its high culinary and medicinal value. However, the quality characteristics of lily bulbs during storage remain unclear. Hence, to clarify the dynamic changes in the physiochemical characteristics of the bulbs during storage, this study analyzed bulbs at 0-, 15-, 30-, 45-, and 60-day vacuum and cold storage, respectively. The results revealed that the water content and pH decreased, while soluble sugar and dietary fiber contents fluctuated. Soluble protein was less affected by the storage time, yet starch was observed to degrade after 45 d of storage. A total of 66 volatile compounds were identified, among them, seven volatiles were dominant across all five storage periods. Fresh Lanzhou lily bulbs (0-day) contained higher water and sucrose contents. During the 45-day storage period, the quality of the lily bulbs was greatly influenced by the contents of starch, total dietary fiber (TDF), soluble dietary fiber (SDF), and esters, and by the contents of fructose, aldehydes, ketones, alkenes, and alkanes after 60 d of storage. Under the combination of vacuum packing and low-temperature storage, the optimal storage of Lanzhou lily bulbs is 45 d. This work is expected to be helpful in evaluating the quality of Lanzhou lily bulbs during storage and promoting the development of the lily industry.

兰州百合球茎贮藏期理化特性的比较

兰州百合鳞茎因其极高的食用和药用价值而受到全球关注。然而，百合鳞茎在贮藏期间的质量特性仍不清楚。因此，为了弄清百合鳞茎在贮藏过程中理化特性的动态变化，本研究分别对真空贮藏和低温贮藏 0 天、15 天、30 天、45 天和 60 天的鳞茎进行了分析。结果显示，水分含量和 pH 值下降，可溶性糖和膳食纤维含量波动。可溶性蛋白质受贮藏时间的影响较小，但淀粉在贮藏 45 天后出现降解。共鉴定出 66 种挥发性化合物，其中有 7 种挥发性化合物在所有 5 个贮藏期都占主导地位。新鲜兰州百合鳞茎（0 天）的水分和蔗糖含量较高。在 45 天的贮藏期间，淀粉、总膳食纤维（TDF）、可溶性膳食纤维（SDF）和酯类的含量对百合鳞茎的质量影响很大，贮藏 60 天后，果糖、醛、酮、烯和烷的含量对百合鳞茎的质量影响很大。在真空包装和低温贮藏相结合的条件下，兰州百合鳞茎的最佳贮藏期为45 d。这项工作将有助于评价兰州百合鳞茎在贮藏过程中的品质，促进百合产业的发展。

期刊介绍： The journal is devoted exclusively to the publication of original papers, review articles and frontiers articles on biological and technological postharvest research. This includes the areas of postharvest storage, treatments and underpinning mechanisms, quality evaluation, packaging, handling and distribution of fresh horticultural crops including fruit, vegetables, flowers and nuts, but excluding grains, seeds and forages. Papers reporting novel insights from fundamental and interdisciplinary research will be particularly encouraged. These disciplines include systems biology, bioinformatics, entomology, plant physiology, plant pathology, (bio)chemistry, engineering, modelling, and technologies for nondestructive testing. Manuscripts on fresh food crops that will be further processed after postharvest storage, or on food processes beyond refrigeration, packaging and minimal processing will not be considered.
