Abstract:

Using water as a control, the effects of calcium chloride treatment at various concentrations (0.5, 1 g/100 mL and
2 g/100 mL) on respiration intensity, total sugar, protein, free amino acid, vitamin C and pectin (protopectin and soluble
pectin) contents in Agaricus bisporus were studied. The results indicated that during storage at 0-2 ℃, 0.5 g/100 mL
calcium chloride treatment could effectively inhibit respiratory intensity, delay the appearance of climacteric, slow down
the reduction of total sugar, protein, vitamin C and protopectin contents, and suppress the rising speed of free amino acids
and soluble pectin contents; 1 g/100 mL calcium chloride treatment could delay the appearance of climacteric, inhibit the
decrease of protein level during the latter storage period (12-14 d), and the content of vitamin C was higher than that of the
control during 0-4 d. With 2 g/100 mL calcium chloride treatment, total sugar was higher during storage period of 0-8 d,
and the content of protein was higher than that of the control during storage period of 12-14 d.

Key words: Agaricus bisporus, calcium treatment, quality
