Ascorbic acid and total phenol in frozen aonla pulp on zero day of storage was found to be 365.5 mg/100g and 2.1 mg/g while in dehydrated aonla pulp it was 2.3 mg/100mg and 14.7 mg/g which was found to decrease with the increase in storage duration. However, significant increase (CD at 5% Level) in total soluble solids (TSS) and non-enzymatic browning was noticed with the advancement in storage duration. The decrease and increase in physico-chemical characteristics were more significant in dehydrated aonla pulp as compared to frozen aonla pulp. Mean score for sensory attributes of dehydrated aonla pulp at zero month of storage was fairly less than frozen aonla pulp. Moreover, there was more significant decrease in value of sensory attributes of dehydrated aonla pulp during six months storage period compared to frozen aonla pulp. Thus, present study was first in its kind to determine and compare chemical composition and overall acceptability of frozen and dehydrated aonla pulp obtained from aonla fruits cv. Chakaiya during storage for optimizing there use in further development of value added aonla product.

Purpose The purpose of the present study was to investigate the effect of camel milk protein hydrolysates (CMPHs) on physico-chemical, sensory, colour profile and textural quality attributes of chevon patties. Design/methodology/approach Camel milk proteins were hydrolyzed with three different proteolytic enzymes, viz., alcalase (CMPH-A), α-chymotrypsin (CMPH-C) and papain (CMPH-P), and dried to powder form before further utilization. Four treatments were prepared with incorporation of CMPH, viz., CMPH 0 per cent (C), CMPH-A 0.09 per cent (T1), CMPH-C 0.06 per cent (T2) and CMPH-P 0.09 per cent (T3), in the product formulation. The developed goat meat patties were evaluated for physico-chemical (pH; emulsion stability, ES; cooking yield, CY; water activity, aw), instrumental colour and texture profile and sensory attributes. Findings The pH, moisture, fat and ES values of goat meat emulsions were comparable amongst treatments as well as with the control; however, treated emulsions had higher ES and moisture content. The pH and moisture per cent of cooked chevon patties varied significantly, whereas other physico-chemical (CY, aw, per cent protein, per cent fat, per cent ash and per cent dietary fibre) as well as dimensional parameters (per cent gain in height and decrease in diameter) were comparable amongst treatments and the control. Hardness, springiness, stringiness, cohesiveness, gumminess and resilience of chevon patties decreased significantly (p < 0.05) with the incorporation of CMPH than that of the control; however, the values were comparable among all the treated products. Protein hydrolysate in chevon patties resulted in significant increase in redness (a*) values, whereas all other parameters (L*, b* and hue) decreased significantly as compared to that of the control. The colour and appearance, texture, juiciness overall acceptability scores were comparable in all the treated products and were significantly (p < 0.05) higher than the control. The flavour scores of C, T1 and T3 were comparable but significantly lower than that of T2. The overall acceptability scores of T1 and T2 were also comparable and significantly higher than C and T3; however, the highest score was recorded for T2. Practical implications Results concluded that chevon patties with acceptable sensory attributes and improved CY and textural attributes can be successfully developed with the incorporation of CMPH. Originality/value The protein hydrolysates of different food proteins could be explored in a same pattern to find out their implication in food matrices.

The physico-chemical properties of commercial canned whole tomatoes (i.e., peeled tomatoes with about 30% tomato juice as packing medium) and the contribution of various analytical parameters to some sensory attributes were evaluated using multivariate statistical analysis. In addition, cluster analysis was used to determine the existence of significant qualitative differences between the old and famous San Marzano variety (as described on the commercial labels by the manufacturers) and traditional (without any specification on the tomato variety) canned whole tomatoes.

A dietary supplement containing multifunctional ingredient sources was formulated and optimized for management of diabetes. The formulated dietary supplement comprised of milk fat and groundnut oil (90:10), whey protein concentrate, skim milk powder and sodium caseinate (50:25:25) and resistant starch and maltodextrin (70:30). The feasibility of the formulated dietary supplement in terms of physico-chemical, microbiological and sensory attributes was evaluated during storage period. The formulated supplement was found to have 4.37, 15.93, 10.15, 3.39 and 66.15 percent moisture, protein, fat, ash and carbohydrate respectively. It was observed that there was slight increase in moisture, free fatty acid, thiobarbituric acid and insolubility index while a decrease in dispersibility and sensory attributes (color and appearance, flavor, overall acceptability) during the storage period. However, the dietary supplement stored at room temperature indicated non-significant changes in all physico-chemical, microbiological and sensory parameters throughout the storage period of 180 days. Thus, dietary supplement prepared had better acceptability for a period of six months.

The MW heating at early or at final stage of drying process to obtain a crispy apple snack was studied. The effect of MW power and time of application was also evaluated on colour, texture, physico-chemical and sensory properties. Apple snack obtained with the MW heating (7.5 min at 3.000 W) at early stage after an osmotic pre-treatment resulted in apple slices more porous and with better sensory attributes than if it is applied at later stage of drying.
