[Spectral analysis of some nutrients and minerals in Agaricus bisporus fruit bodies harvested at four different maturity stages].
The contents of nutritional elements such as Na, K, P, Ca, Mg and trace elements such as Cu, Se, Mo, Fe in Agaricus bisporus fruit bodies harvested at four different maturity stages (stage I, II, III, IV) were analyzed by ICP-AES, and the contents of some nutritional ingredients such as water, soluble protein, soluble sugar and ascorbic acid were also investigated. The results showed that the contents of Na, K, P, Mg, Cu, Se and Mo in stage I was respectively higher than those in the other three stages (alpha = 0.05), and the contents of Ca and Fe were respectively higher than those in stage II and III. The content of Se in stage IV was respectively higher than that in stage II and III, while the content f Na was respectively higher than that in stage II. The content of Cu in stage IV was respectively higher than that in stage III. The contents of K, P, Ca, Mg, Mo and Fe in stage II and III were respectively higher than those in stage IV. The content of water in stage IV was respectively higher than that in stage I and III, and had no significant differences from that in stage II. There were no significant differences in the contents of soluble protein, but the content of soluble sugar was significantly lower in stage IV. The content of ascorbic acid in stage III had no significant differences from that in stage I, but it was respectively higher than that in stage II and IV. The content of ascorbic acid in stage I and IV was respectively higher than that in stage II. The differences in the nutritional ingredients and mineral elements in the four stages of Agaricus bisporus fruit bodies provide academic data for the consumers and food industries while choosing Agaricus bisporus produces.
