“…(2003a, b) observed that the samples stored at reduced O 2 levels had higher vitamin C content due to lower oxidation process. Vitamin C degradation is due to both autoxidation and enzymatic degradation viz., ascorbate-oxidase, polyphenol-oxidase, cytochrome-oxidase and peroxidase (Barath et al 1993;Erdman and Klein 1982). Hossain and Gottschalk (2009) reported that ascorbic acid degraded linearly with storage time both in room and cool chamber environments.…”

Influence of vacuum packaging on seed quality and mineral contents in chilli (Capsicum annuum L.)

Studies were carried out to find out the influence of vacuum packaging on physical parameters of whole chilli and biochemical constituents in chilli seeds. Chilli fruits were stored in vacuum packed and jute bags stored at room temperature (25±2°C), cold storage (4±1°C) under both light and dark conditions for a period of 24 months. At the end of the storage period, seeds were separated from fruits and various parameters viz., moisture content, capsaicin content, ascorbic acid, carbohydrates, protein and mineral elements like Fe, P, Na and K were analyzed. It was observed that the samples stored in vacuum packed bags maintained the quality with least deterioration in all the quality parameters compared to samples stored in jute bags.

“…Vitamin C in Cryovac PD 961® packs were on par with freshly cut green bell pepper, while other types of packing resulted a severe reduction in vitamin C during storage. Vitamin C is susceptible to oxidation by ascorbic acid oxidase, and losses can be minimized by modified atmosphere packaging of the produce after harvest (Howard and Hernandez-brenes 1998;Barth et al 1993). The microbiological quality was significantly lower in all packs, in comparison with fresh produce.…”

Present study was aimed at understanding the effect of pretreatments and modified atmosphere packaging on the quality of fresh-cut green bell pepper (Capsicum annuum L.) during low temperature storage. Dip treatment of freshly cut green bell pepper pieces in 2 % calcium propionate followed by surface drying and subsequent packing in cryovac PD961 film which maintained an equilibrium modified atmosphere of 13-14 % O2 and 7 % CO2 helped to extend the marketability till 9 days storage at 8°C. The microbiological quality was at the best level up to 6 days of storage, as evidenced by a surge in aerobic plate count, pectinolysers and pseudomonads on subsequent days. Head space volatile analysis of the produce at regular intervals showed a reduction in monoterpenoids and simultaneous increase of aldehydes and ketones, sesquiterpenoids, esters, furans and pyrazines during storage. Principal component analysis of the head space volatiles identified, cis -ocimene, 1,3, 8-paramenthatriene, trans 3-caren 2-ol, bergamotene, 2-hexenal, ethyl 1-decanol, (E)-3-hexenol and heptane thiol as the markers of freshness in minimally processed green bell pepper.

“…The two methods more widely used are cooling (Rodrigues and Rosa 1999) and modified atmosphere (MA) (Makhlouf et al 1989, Barth et al1993). Treatment with controlled or modified atmosphere substantially reduces senescence, delaying chlorophyll degradation and decreasing respiratory activity (Barth et al 1993, Coupe et al 2003b. Also, it has been used 1-methylcyclopropene (1-MCP), a substance that blocks ethylene receptors, as post-harvest treatment (Fan and Mattheis 2000).…”

Loss of sugars contributes to accelerate postharvest senescence of broccoli. Several treatments have been developed to delay senescence, but in many cases their effects on sugar metabolism were not analyzed. We studied the effect of harvest at different times of day (08:00, 13:00 and 18:00 h) and of several postharvest treatments as heat treatment (HT), modified atmosphere (MA) and 1-methylcylcopropene (1-MCP) on sugar levels and activities of enzymes related to sucrose and starch degradation. Harvesting at the end of day delayed the loss of chlorophylls and caused the lowest decrement in sugars, although no differences in invertase, sucrose synthase and β-amylase activities were detected among samples. Treatments of MA and 1-MCP caused a lower loss of glucose and fructose, while HT caused a lower decrement of sucrose. Treated samples maintained higher levels of chlorophylls. The treatments reduced the activity of invertase and sucrose synthase and induced higher levels of β-amylase activity. Harvesting at the end of day and performing simultaneously a MA treatment could be a good combination to maintain the green color of the inflorescence and sugar levels during postharvest of broccoli.
