Methods for identifying the quality of dried sea cucumber

The quality of dried sea cucumber can be comprehensively identified through dimensions such as appearance, color, odor, texture, and foaming rate. High quality dried sea cucumber usually has the characteristics of complete and uniform appearance, natural and glossy color, fresh and odorless odor, hard and dry texture, and high foaming rate.

1. Complete and uniform appearance

High quality dried sea cucumber individuals are plump, with no defects or obvious damage on the surface, and the spike like protrusions are arranged neatly. Poor quality products may show signs of breakage, deformation, or insect infestation, with uneven appearances. Excessive rubbing or improper storage during the processing can cause damage to the appearance, affecting the taste and nutritional value of the food.

2. Natural and glossy color

Normal dried sea cucumber appears black brown or gray black, with a natural matte finish on the surface. The color of dyed sea cucumber is too uniform and bright, which may contain chemical additives. Some inferior products may show dark green or gray white spots due to mold growth, which poses a food safety risk.

3. Fresh and Odor Free

Good quality dried sea cucumber has a slight fishy smell, without pungent chemical or putrid odors. If you smell a sour, moldy, or sulfur-containing odor, it may be due to illegal addition or improper storage. When purchasing, you can lightly smell the belly of sea cucumber, which is the area where the odor is most likely to expose the problem.

4. Hard and dry texture

High quality dried sea cucumber has a hard and dry feel, with a crisp sound when struck, and a moisture content of less than 15%. Damp products have a soft texture and are prone to bending and deformation, which may breed mold. Products that are prone to fragility due to excessive drying are also considered processing defects.

5. High foaming rate

High quality dried sea cucumber can expand to more than three times its original volume after foaming, with thick and elastic flesh. Poor quality products have a low foaming rate and may experience outer layer detachment or inner core hardening. Clear and non turbid water quality is also one of the key points for identification.

It is recommended to choose products from legitimate channels and check food testing reports when purchasing dried sea cucumbers on a daily basis. Store in a cool and ventilated place to avoid moisture or high temperatures. The soaking process requires frequent water changes to remove residual impurities, and thorough cleaning before cooking. For individuals with special physical conditions, a small amount should be attempted for the first time to observe for allergies. If obvious quality problems are found with sea cucumbers, they should be immediately stopped from consumption and reported to regulatory authorities.
