the physico-chemical characteristics and physiological qualities of palm (phoenix dactylifera) fruit strongly depend on the storage conditions. storage environment and packaging type are the factors most influencing on the quality of dates during their storage. date fruits were packed within an aerobic atmosphere, vacuumed in pa/pe pouches and stored at different temperatures (-20, 4, 25 and 40...

in order to alleviate chilling injury in pomegranate (punica granatum) cv. rabab due to cold storage, the fruits were dipped in 0.7, 1.4 and 2 mm of salicylic acid (sa) for 10 min. after 1, 2 and 3 months of storage at 2°c, the fruits were tested for chilling injury (ci) as well as some biochemical parameters. the results revealed that with increase in storage time, ci and ion leakage (il) incr...

The effects of the use of essential oil of Rosmarinus officinalis on the chemical quality and fatty acids of fish fillets of Ctenopharyngodon idella were investigated during frozen storage at -18 ºC for 6 months. Fish fillets were divided into three groups the control (C) without rosemary essential, the second group with 0.2 % rosemary essential oil (A) and the third with 0.4 % rosemary essenti...

the harvest date more influenced on postharvest quality during storage. in present study, fruits were harvested at four date base on total soluble solids content (5.5, 6.5, 7.5, and 8.5%) and then stored at 0.5 ºc and 80-90% rh, for 18 weeks. the samples were taken in 6th, 12th and 18th interval weeks and evaluated some parameters including weightless, losses, firmness, tss, ta, tss/ta, ascorbi...

the ability of whey protein concentrate (wpc) (1% w/v) and/or honey (2% and 4% w⁄v) to improve lactic acid bacteria (streptococcus thermophilus and lactobacillus delbrueckii subsp. bulgaricus) growth and viability in yoghurt during a 21 day period of storage was investigated. another focus of this study was to examine fermentation kinetics and post-acidification rates through ph and lactic acid...

effects of catechin for preventing black spots forming in whiteleg shrimp (litopenaeus vannamei) were evaluated. for processing whole shrimp, catechin was used at a concentration of 0.2 and 0.3 % for 15 minutes. sodium metabisulfite was used at a concentration of 3 % for 10 minutes as control samples. without antioxidant shrimp were used as control samples too. treatments quality was evaluated ...

Packed bed units generally, represent the most suitable storage units for air heating solar systems. In these systems the storage unit receives the heat from the collector during the collection period and discharges the heat to the building at the retrieval process. A method for sizing of packedbed storage in an air heating system is represented. The design is based on the K-S curves, which hav...
