Evaluating The Effect of Calcium Chloride Plus Sodium Alginate Treatments on Button Mushroom Shelf Life Quality

Abstract

In this study, distilled water (control), 1% calcium chloride (CaCl2) (w/v), 1% sodium alginate (w/v), and combination with 1% CaCl2 + 1% sodium alginate (w/v) solutions were sprayed on freshly harvested button mushrooms.. Treated mushrooms were stored in polypropylene boxes during 20 days at 4±1°C. Physical and chemical properties of treated mushrooms were investigated at five days intervals during storage. The present results showed that treatment of 1% CaCl2 revealed close effectiveness on weight loss with 1.21%, L* color value with 81,76 and cap opening percentage with 11% in addition that minimum decrease in firmness with 2.2 N of the mushrooms compared to other treatments at end of storage. The experiment results could suggest the 1% CaCl2 application for mushroom quality and shelf life were more observable up to 15 days
