Item type:Publication, Preharvest calcium chloride sprays improving physicochemical quality of mulberries (Morus alba L. ‘Chiang Mai 60’) during refrigeration(2024-06-01); ; Ahuja, A. JunpatiwThe aim of this work was to investigate the efficiency of preharvest CaCl2 sprays on quality of ‘Chiang Mai 60’ mulberries during refrigeration. The mulberries at the stage of 40 days after anthesis were sprayed with water (control), 0.5 or 1% CaCl2. The fruits were then harvested after spraying for 5 days and refrigerated at 5°C for 6 days. The visual appearance, texture, total soluble solids (TSS) content, total acidity (TA), antioxidant activities and certain secondary metabolites of the mulberries were monitored. Both CaCl2 sprays had no effect on the visual appearance during storage. Both CaCl2 sprays enhanced fruit firmness and delayed the fruit softening during refrigeration. Both CaCl2 treatments delayed the increased TSS content and maintained the TA content. Total phenols, ascorbic acid and anthocyanin contents of the mulberries were enhanced by the CaCl2 sprays. Both CaCl2 sprays delayed the decreased antioxidant capacity and enhanced the free radical scavenging activity during the refrigeration. The efficiency of 0.5 and 1% CaCl2 preharvest sprays on improving postharvest quality of the mulberries was not different. This indicates that CaCl2 preharvest sprays improved postharvest quality of the mulberries which 0.5% CaCl2 is the suggested concentration. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Effects of preharvest boron, calcium sulfate treatment and postharvest calcium chloride peduncle infiltration on chilling injury alleviation of queen pineapple cv. Sawi fruit(2021-07-01); The aim of this study was to determine the incorporative effects of preharvest boron (B) or calcium sulfate (CaSO<inf>4</inf>) application and postharvest calcium chloride (CaCl<inf>2</inf>) peduncle infiltration on chilling injury (CI) alleviation of Queen pineapple during commercial cold storage (13°C). Pineapple fruits were sprayed with 0.25% B four times a month after one month of anthesis, or CaSO<inf>4</inf> (100 kg per 400 m<sup>2</sup>) was applied during fruit development. The fruits were harvested after 135 days of flower induction. Both preharvest B and treated fruits were then peduncle-infiltrated with 2% CaCl<inf>2</inf> for 3 days and stored at cold temperature (CT) for 14 days. Control fruits were not peduncle-infiltrated with CaCl<inf>2</inf>.Visual appearance of half cut fruit, CI score, the amount of fruit having CI, colour attributes, browning index (BI) value and electrolyte leakage (EL) of tissue adjacent to the core were determined after storage at CT for 7 or 14 days, followed by leaving at room temperature (RT), 28 ± 1°C, for 2 days. The results show that the incorporative application of preharvest CaSO<inf>4</inf> with CaCl<inf>2</inf> peduncle infiltration (CaSO4+CaCl2) alleviated CI, delayed decrease in lightness (L*) and chroma values, and also increased BI and total colour difference (∆E*) values during storage compared with control and the incorporative application of preharvest B with CaCl<inf>2</inf> treatment (B + CaCl<inf>2</inf>). The treatment with CaSO<inf>4</inf> + CaCl<inf>2</inf> lowered CI severity and the amount of fruit having CI when compared to B + CaCl<inf>2</inf> and control treatments, respectively. Both treatments had no effect on the hue value over the storage period. Therefore, CaSO<inf>4</inf> + CaCl<inf>2</inf> treatment is an alternative method for alleviating CI of Queen pineapples. - Some of the metrics are blocked by yourconsent settings
