Optimization of antifungal edible pregelatinized potato starch-based coating formulations by response surface methodology to extend postharvest life of ‘Orri’ mandarins was written by Soto-Munoz, Lourdes;Palou, Lluis;Argente-Sanchis, Maricruz;Ramos-Lopez, Miguel Angel;Perez-Gago, Maria B..

Antifungal composite edible coatings (ECs) formulated with pregelatinized potato starch (PPS, 1.0-2.0% weight/weight) as biopolymer, glyceryl monostearate (GMS, 0.5-1.5%, weight/weight) as hydrophobe, glycerol (Gly, 0.5-1.5%, weight/weight) as plasticizer, and sodium benzoate (SB, 2%, weight/weight) as antifungal agent were optimized using the Box-Behnken response surface methodol. to extend the postharvest life of ‘Orri’ mandarins. The second order polynomial models satisfactorily fitted the exptl. data, with high values of the coefficient of determination for the different variables (R2>0.91). The individual linear effect of GMS concentration was significant in all the responses evaluated, whereas PPS only affected emulsion viscosity, fruit tacking, and weight loss of coated mandarins. Gly only affected acetaldehyde content in the juice of coated mandarins when interacted with PPS and in the quadratic effect. The optimum concentrations of PPS, GMS, and Gly based on maximum fruit quality and required emulsion properties were predicted to be 2.0, 0.5, and 1.0% (weight/weight), resp. The optimized EC reduced weight loss of mandarins and created a modified atm. within the fruit without neg. affecting the overall acceptability of the fruit. On the other hand, the optimized EC significantly reduced postharvest green and blue molds and sour rot on mandarins artificially inoculated with the pathogens Penicillium digitatum, Penicillium italicum, and Geotrichum citri-aurantii, resp. Therefore, the optimized antifungal EC containing SB showed potential to control the main postharvest diseases and maintain the overall quality of ‘Orri’ mandarins and could be a suitable alternative to com. citrus waxes formulated with conventional chem. fungicides. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Reference of 31566-31-1).
Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Reference of 31566-31-1
