“…MAP or 1-MCP+MAP significantly reduced weight loss. Similar results were also reported by Carvalho and Clemente (2004), Tano et al (2007), Jia et al (2009), Nath et al (2011 on MAP used broccoli. Besides, Kasim et al (2007) reported that combined use of 1-MCP treatment with polyvinylchloride film package reduced weight loss of broccoli heads compared with other films.…”

Broccoli is rich in health-promoting compounds such as ascorbic acid and glucosinolates. However, amount of such compounds inevitably decrease along with the storage. This study was conducted to investigate the effects of 1-methylcyclopropene (1-MCP) and Modified Atmosphere Packaging (MAP) treatments alone or in combination on postharvest life and quality of broccoli heads during cold storage. MAP and 1-MCP+MAP significantly reduced weight loss, delayed surface color changes and chlorophyll breakdown, maintained visual quality, ascorbic acid, total phenol, soluble solid contents and titratable acidity compared with control as well as 1-MCP treatment. In 1-MCP plus MAP treated florets, approximate 47% and more chlorophyll and 24% more total phenol contents were found compared to control florets. 1-MCP plus MAP application better performed in maintaining the quality of broccoli florets during 28-day-storage. Overall results revealed that combined treatment can be recommended for commercial broccoli storage at 0 °C.

“…On the other hand, "strong off odour" was observed in non-perforated packages mainly due to fermentative respiration leading to accumulation of alcohols, aldehydes and thus ketones and synthesis of off odour under non-perforation conditions. For control samples , as observed by various other researchers (Toivonen 1997;Carvalho and Clemente 2004;Rai et al 2009a), no off-odour could accumulate inside the packages as they could escape easily to the storage environment.…”

Biochemical and physiological changes in Fenugreek (Trigonella foenum- graecum L.) leaves during storage under modified atmosphere packaging

et al. 2011

Fenugreek (Trigonella foenum-graecum L.), is a highly respiring leafy vegetable enriched with many nutrients and other active ingredients such as protein, vitamin C, niacin, potassium, alkaloids, lysine and Ltryptophan as well as steroidal saponins which are beneficial for human health. Both, quantitative and qualitative losses in this vegetable can be reduced by appropriate packaging and storage techniques which have not been applied hitherto. This study was taken upon to assess the potential of macro-perforated MAP for storage of fenugreek leaves. Packages (bag area: 0.075 m 2 ) made from polypropylene (PP) film (Thickness: 35 μmm) were selected for the storage studies. The leaves were packaged in macroperforated (2 perforations, perforation diameter: 0.3 mm each, with and without mustard seeds as natural absorbents) as well as in non-perforated PP film packages with and without mustard seeds. 10 g of mustard seeds were placed inside the packages to check water accumulation. The packaged samples were stored for 6 days at 75% relative humidity (RH) at 15°C to check water accumulation, if any. Different physiological and biochemical characteristics which generally affect the post-harvest life of the produce were monitored during the storage period. Results of the study suggested that among all the treatments, packaging of fenugreek in two perforation packets with mustard seeds resulted in best maintenance of chlorophyll, ascorbic acid, phenols and aroma. Water accumulation was also consoled due to mustard seeds after 6 days of storage.

Jamun or Indian blackberry (Syzygium cumini L.) is a minor and highly perishable fruit enriched with flavonoids, essential oils, anthocyanins phenolic compounds and other antioxidants. The quantitative and qualitative losses in this seasonal fruit are tremendous and can be reduced by appropriate packaging and storage techniques which have not been applied hitherto. This study was undertaken to extend the shelf-life as well as to assess the biochemical, microbiological and physiological changes in jamun fruit under perforated and non-perforated modified atmosphere (MA) conditions. Fruits were stored under differential MA in macro-perforated (1 and 2 perforations, 0.3 mm dia. each) and non-perforated polypropylene (PP) film packages (Thickness: 35 μm, bag area: 0.036 m 2 ) at 5°C and 75% relative humidity (RH) for 23 days. Sachets containing white silica gel beads were placed inside all the packages to check water accumulation, if any. Different physiological, biochemical and microbiological characteristics which generally affect the postharvest life of the produce were monitored during the storage period. Results of the study suggested most of the subjectively and objectively determined qualitative parameters to be retained satisfactorily under macro-perforated packaging treatments. Further, the microbiological analysis, surmised that the fruits could be stored for long term using packages with 1 macro-perforation.Keywords Antioxidants . Jamun . Modified atmosphere packaging . Headspace . Pigments . Microbial load Indian blackberry (Syzygium cumini L.), commonly known as jamun is a minor and under-utilised tree-fruit of Indian subcontinent. The plant belongs to Myrtaceae family and grows naturally in clayey loamy soil in tropical as well as in sub-tropical zones of Indo-gangetic plains. These species are reported to be very rich in tannins, flavonoids, essential oils, anthocyanins and other phenolic constituents (Sharma et al. 2003;Reynertson et al. 2008). The purple coloured fruits are available abundantly during summer season for a short span of time, causing a seasonal glut. Jamun contains 19.7% carbohydrates, 0.7% proteins, 0.02% calcium, 0.1% fat, 0.01% phosphorous, 0.4% mineral matter, 0.1% iron and 0.9% fiber (Singh et al. 1967;Benherlal and Arumughan 2007). Besides, they contain anthocyanins which are the most important and widespread groups of colouring matters in plants. These intensely coloured water soluble pigments are responsible for nearly all colours in leaves, petals and fruits of higher plants. Jamun fruits and seeds are sweet, acrid and sour and they are used for treatment and control of diabetes, diarrhoea and ringworm. It is also reported to be a blood pressure regulator (Bhargava et al. 1968). Jamun trees are available around parks, on roadsides, on avenues and are good windbreakers. On account of its unorganised farming, consolidated information regarding its area and production in India is apparently not available. The fruits are highly perishable and are sold by the roadside vend...
