This study evaluated the impact of different cooking methods on the nutrients and taste-active components of Lentinus edodes mushrooms. The results showed that microwaving increased the nutritional value and antioxidant activity of the mushrooms, while pressure cooking and frying increased the flavor compounds.
This work evaluated the effect of different cooking methods (boiling, steaming, microwaving, frying and pressure cooking) on the nutrients, antioxidant activities, volatile and nonvolatile taste-active components of three varieties of Lentinus edodes (808, 0912 and LM) from Guizhou Province. The results showed that LM had the most polysaccharides, 0912 had the most minerals, but LM, 808 and 0912 had low amounts of polyphenols, dietary fiber and proteins, respectively. The dietary fiber and protein were decreased by 4.1 similar to 38.7% and 4.1 similar to 44.0% during cooking, while microwaving improved the nutritional value of the Lentinus edodes by increasing the polysaccharide (88 similar to 103 mg/g to 93 similar to 105 mg/g) and polyphenol content (6.4 similar to 8.1 mg/g to 7.5 similar to 11.2 mg/g), thereby strengthening the antioxidant activity. The nucleotides were all destroyed after cooking, especially frying or boiling. The glutamate content was the highest in LM and 808, and the methionine content appeared to be the highest in 0912. Pressure cooking and frying increased the proportions of sweet and umami amino acids and decreased the proportion of bitter amino acids, creating more aroma-active compounds. In summary, microwaving increased the content of bioactive compounds and antioxidant activities, and it preserved nonvolatile taste-active components, while pressure cooking and frying were the best methods for increasing the flavor compounds.
