step 3), fishing out the soaked whitebait, leaching with clear water, and draining;
step 4) flatly paving the whitebait obtained in the step 3) on a sieve, and putting the whitebait into a hot air drying box to perform dehydration and drying treatment on the whitebait;
and 5) putting the dried whitebait into a vacuum packaging bag, and vacuumizing for storage.
Further, in the step 1), when the frozen whitebait is taken, the whitebait is naturally thawed in an environment of less than 15 ℃ so as to reduce the damage to the structure and nutrition of the whitebait to the maximum extent.
Further, in the step 2), the soaking solution is composed of 0.5-1% of composite water retention agent, 1.0-1.5% of yeast extract, 1.0-1.5% of salt, 0.02-0.03% of tea polyphenol and the balance of water, and the mass ratio of the whitebait to the soaking solution is 1.
Further, in the step 4), the hot air drying temperature is 40-50 ℃, the air speed is 0.1-0.2 m/s, and the drying time is 6-7 h.
Further, in the step 4), a finished product is obtained until the water content of the dried whitebait is below 7%.
The beneficial effects of the invention are:
1. the dried whitebait product processed by the invention is subjected to fishy smell removing treatment by adopting yeast extract, tea polyphenol and other natural substances before drying processing, wherein the tea polyphenol has good antioxidation, and can effectively prevent the dried whitebait from oxidative discoloration in the storage process; the soaking treatment of the compound water retention agent plays an important role in maintaining the quality of the rehydrated whitebait, and meanwhile, the operation is simple, and the mass production is convenient.
2. The dried whitebait prepared by the process method has white color and semitransparent texture, the meat quality is softer, the product quality and the appearance are better, and the quality difference between the rehydrated whitebait product and the fresh whitebait product is smaller.
3. The method is reasonable, reliable and stable in technology, and can be widely used in whitebait drying processing.
