"BRS Isis" is a novel hybrid seedless table grape with large reddish bunches. This cultivar is cultivated in tropical and subtropical areas and has potential to be exported overseas; however, under these growth conditions, grapes can be severely damaged by gray mold (Botrytis cinerea), the main postharvest disease of table grapes. Thus, this study aimed to evaluate different pre- and postharvest strategies to extend the storage period of ?BRS Isis? seedless table grapes. The treatments consisted of grapes packed into carton boxes under cold storage (1 ◦C and high relative humidity), pre- and/or postharvest treatment with potassium bicarbonate or a biological control agent (Bacillus subtilis), all with Botrytis inoculation. Additionally, two controls, with and without Botrytis inoculation, were also evaluated. The experimental design was completely randomized with eight treatments and three replications, and each plot consisted of four bunches. After a 50-day cold storage period, the carton boxes were kept for five days at room temperature (22 ◦C). Gray mold incidence and water loss, as well as soluble solids (SS), pH, titratable acidity (TA), SS/TA ratio, and color attributes were evaluated during both periods. Cold storage effectively reduced gray mold in "BRS Isis" seedless grape for a period of 50 days, even when grapes were inoculated; however, no difference among treatments was observed. Higher water loss was observed in both non-treated control treatments. Keywords: Bacillus subtilis; Botrytis cinerea; potassium bicarbonate; salt strategy; seedless grapes Menos"BRS Isis" is a novel hybrid seedless table grape with large reddish bunches.

The physical, chemical, or enzymatic modified starches are well suited for industrial applications. Acid hydrolysis changes the physicochemical properties without impairing the granular structure of starch. The acid hydrolysis in alcoholic solution can recover the granule starches after modification. Starch, the most abundant carbohydrate in grains, roots and tubers, is composed by amylose and amylopectin. Corn starch represents 85% of the global starch market. The aim of this study was to evaluate the effects of soft acid, acid?ethanol and acid methanol solutions, considering its application in the paper industry. One sample remained as native. The other six samples were modified with acid, acid?ethanol and acid? methanol solutions, at concentrations of 0.1 and 0.5 mol L-1 (hydrochloric acid). The acid treatment changed the thermal (TG) and rheological (RVA) properties of the corn starch. The TG/DTG results showed shifted (up to 8 C) stability temperature ranges for the samples treated with a higher concentration of HCl in ethanol and methanol solutions. The RVA results for final viscosity of the treated samples showed an intense reduction of 1405 cP related to the native sample. DSC curves demonstrated that the treatments slightly modified the gelatinization behavior of the starch. The micrographs showed small changes in granules average diameter size after the modification process. Acid hydrolysis did not change the crystalline pattern of corn starch, and its relative crystallinity was slightly affected. According to the results obtained for the acid/alcohol, modified starches present suitable properties for their application in the paper industry.
