Effects of Flammulina velutipes Residue Extracts on Protein Nutritional Value of Agaricus bisporus
The study was carried out to reveal the effects of Flammulina velutipes residue extracts on protein nutritional value of Agaricus bisporus,by treating casing soil with two extracts which were prepared in the conditions of heating and room temperature respectively(HDT and RDT) and tap water as a control.The protein and amino acids components of the fruiting bodies were tested to compare the nutrition value of protein with the international adopted assessment method.The results showed that the amino acid score (AAS),chemical score(CS),score of ratio coefficient of essential anino acid (SRCAA),essential amino acid index (EAAI),biological value (BV) and nutritional index (NI) of the RDT-treated fruiting bodies were higher than the control and all the indexes of the HDT-treated fruiting bodies were higher than the control except CS,indicating that the fruiting bodies of Agaricus bisporus treated with the Flammulina velutipes residue extracts had higher nutrition value.As a result,it was advantageous for the fruiting body to accumulate protein nutrient and raise nutrition value that Flammulina velutipes residue extracts were used in the process of Agaricus bisporus production.
