In this work, sun drying, hot-air drying and microwave drying were used to study the effects of drying methods on nutrients of abalone. The results showed that the contents of polysaccharide and total sugar in sun dried abalone were significantly higher than that in hot-air or microwave dried abalone. However, the contents of collagen and amino acids of abalone were significantly lower than that in hot-air or microwave dried abalone. Furthermore, it was also found that hot-air dried abalone not only had similar collagen content compared to microwave dried abalone, but also had a higher amino acid content than microwave dried abalone. Therefore, hot-air drying and microwave drying are better than sun drying from the aspects of product quality and production efficiency.
