Unravelling physiological changes in peeled and unpeeled shallot during storage
摘要
Shallot (Allium ascalonicum L.) is a valuable horticultural product that is often used fresh, but it can go bad quickly after being picked if it is not stored correctly. The physicochemical characteristics of shallot bulbs (peeled and unpeeled) were investigated during storage. Peeling shallot bulbs involves removing the top layer of dry skin with a stainless steel knife. The results showed that treating shallot bulbs without peeling them helps keep their quality and makes them last longer. Unpeeled shallots can last up to six weeks, which is four weeks longer than peeled shallots. Also, treating shallot bulbs without peeling them can slow down changes in their physiology after harvest while they are being stored. This includes inhibiting respiration, slowing weight loss, lowering moisture levels, and making them less firm. It can also stop rooting, sprouting, and fungal attacks. Aspergillus niger, Penicillium sp, and Fusarium sp are some of the other types of fungi that attack peeled shallots. Aspergillus niger and Penicillium sp. are the only things that attack unpeeled shallots. So, unpeeled shallots are a good way to keep shallots fresh while they are being stored.
