1, fresh-keeping of dry goods: after purchase, put it in a fresh-keeping box or sealed fresh-keeping bag and put it in the refrigerator for fresh-keeping or cold storage. Or completely dry (but not in direct sunlight) and put it in a ventilated, cool and humid place. If you find that the bird's nest is slightly moldy due to improper handling, you can wipe it with a toothbrush and dry it (remember not to expose it to the sun). Seriously affect the quality). Note: If bird's nest is found to be damp, it is recommended to air-dry it first, even if it is intended to be stored in the refrigerator. If the bird's nest has been enzymatically blackened, it should not be eaten any more, because the bird's nest has been eroded by bacteria and the nutrients have been lost. Bird's nest is a very precious food and must be well preserved. 2. Preservation (soaking) of wet goods: packed in a clean container, sealed, waterproof and oil-proof, which can be kept fresh or refrigerated for 7- 15 days. You'd better use it as much as possible, and don't send too much at a time. Because the well-developed bird's nest will cause a certain degree of nutrient loss with the passage of storage time. 3. Centralized preservation: put the bird's nest in the freezer before opening it. Please eat as soon as possible after opening. If you can't eat it all at once, keep it in the freezer. Note: Pay attention to the difference between freezer and freezer. The above are several ways to preserve bird's nest. Generally, as long as the bird's nest is preserved in the right way, good results can be achieved. However, Yan Sichao's health experts still suggest not to store a large number of bird's nests at one time to avoid unnecessary losses caused by improper preservation.
