Fifteen cultivated (Ten desi, five kabuli) and fifteen wild species of chickpea (Cicer arietinum L.) were compared for nutritional traits, antinutritional factors and antioxidant potential. The average crude protein content in desi, kabuli and wild species was found to be 25.31%, 24.67% and 24.30%, respectively; total soluble sugars in these genotypes were 38.08, 43.75 and 33.20 mg/g, respectively and total starch content in these genotypes was 34.43, 33.43 and 28.77%. Wild species had higher antioxidant potential as compared to cultivated genotypes due to higher free radical scavenging activity, ferric reducing antioxidant power and reducing power. Kabuli genotypes had lower antioxidant potential than desi genotypes. Desi genotype, GL 12021 had high crude protein and total starch content, lower phytic acid and saponin content and higher antioxidant potential. GNG 2171 had high crude protein and total soluble sugar content and lower tannin and phytic acid content. Kabuli genotype L 552 possessed high total soluble sugar and total starch content, high Zn and Fe content and lower tannin, saponin and trypsin inhibitor content. Wild species C. pin ILWC 261 had high crude protein, lower phytic acid and trypsin inhibitor content and higher DPPH radical scavenging activity and hydroxyl radical scavenging activity. The observed diversity for quality traits in cultivated and wild genotypes can be further used.

Peach (Prunus persica) fruits of cv. 'Earli Grande' were treated with CaCl 2 (4 and 6%) and stored at 0-2°C and 85-90% RH for 21 days followed by storage at ambient conditions (28-30°C, 65-70% RH) for 72 h. CaCl 2 at 6% effectively in reduced spoilage, physiological loss in weight (PLW) effectively reduced and maintained fruit firmness, palatability rating, acidity, vitamin A content and pectin methyl estrase (PME) activity during storage. Results revealed that peach fruits harvested at optimum stage followed by post-harvest dip in 6% CaCl 2 solution for 10 min can be stored for 3 weeks in cold storage (0-2°C, 85-90% RH) with post-storage shelf-life of 3 days at ambient conditions (28-30°C, 65-70% RH) with acceptable edible quality of fruits.

BACKGROUND‘Patharnakh’ pear, a dominant cultivar in the Punjab province of India, has a shorter storage life as it matures during the hot and humid weather. Studies have reported that postharvest chemical treatments have a major role in improving the storage life of the fruit. In this study, the efficacy of different concentrations (1, 2, and 3 mmol L−1) of salicylic acid (SA), a well‐known signaling molecule, was explored to overcome browning and maintain the postharvest quality of the Patharnakh pear during cold storage.RESULTSSA treated pears were better than the untreated fruits in all of the studied parameters. SA application alleviated the rate of weight loss and respiration, and lowered the decay percentage. The efficacy of SA in the reduction of polyphenol oxidase (PPO) activity, which correlates negatively with the total phenolic content, was quite noticeable. The SA treated fruits exhibited a slower oxidation of the total phenol content by inhibiting the action of PPO and retaining the total phenolic content, leading to lower incidence of browning. SA effectively maintained the ascorbic acid content and superoxide dismutase activity. Total soluble solids, titratable acidity, ascorbic acid, and pH of the pears were highest with the SA treatment.CONCLUSIONThe 2 mmol L−1 SA treatment exhibited the best result of reducing fruit decay and tissue browning, and maintaining the postharvest quality parameters of pear up to 60 days of cold storage. © 2020 Society of Chemical Industry

The effect of different temperature regimes on ripening quality of mango Dashehari was investigated. Fruits were kept at 20, 25 °C in temperature controlled chambers and at room temperature. Fruits were analyzed periodically for physico-chemical characteristics after every 24 h interval up to 168 h of ripening period. Development of soluble solid contents (SSC), flesh softening and physiological loss of weight of fruits occurred progressively during ripening. Progression of ripening changes in fruit were found to be less at 20 and 25 °C than at room temperature.-carotene content of pulp improved with ripening but declined after 144 h. Sensory quality (SQ) of mangoes ripened at lower temperature maintained for longer duration and were more acceptable than fruits ripened at room temperature. Pearson's correlation matrix studies showed the inverse relationship of quality parameters SSC, -carotene and SQ with firmness and titratable acidity during progressive ripening of fruits. Further, principal component analysis for extensive view of changes in quality parameters and their contribution to overall variability revealed that sensory quality (F1) contributed to maximum variation in ripening indices of fruit.
