Analysis and evaluation of nutrient composition of reed mushroom foot waste.

The experiment aims to determine the nutritional components of reed mushroom foot waste and evaluate its nutritional value. The conventional feed nutrient determination method was used to measure the content of crude protein, crude fat, moisture, crude ash, and main trace elements in reed mushroom foot waste. The internationally accepted non-biological evaluation method was used to assess the nutritional value of protein. The results showed that the reed mushroom foot waste contained 24.76% crude protein, 0.29% crude fat, 11.78% moisture and 7.46% crude ash, the content of main mineral elements in reed mushroom foot waste was Cu 57 mg/kg, Fe 212 mg/kg, Mn 31 mg/kg and Zn 66 mg/kg. A total of 17 kinds of amino acids were detected in reed mushroom foot waste. The ratio of essential amino acids (EAA) to the total amino acids (TAA) was 0.40, and the ratio of non-essential amino acids (NEAA) to TAA was 0.60. The results of AAS showed that the first limiting amino acid was valine, the second limiting amino acid was methionine, and the third limiting amino acid was methionine + cystine. The EAARR score of reed mushroom foot waste was 66.5%, and the GRG method score was 0.78. The study indicates that reed mushroom foot waste can be used as a high quality protein feed raw material, which has the value of development and application. [ABSTRACT FROM AUTHOR]
