background: sohan is an iranian traditional brittle confection which its ingredients are susceptible to oxidation and microbial contamination during storage. this experimental study was designed to determine the effect of damask rose (rosa damascena mill.) extract on some chemical, microbial, and sensory properties of sohan during storage at 25 °c. methods: the sohan ingredients were mixed, bak...

the objectives of this paper were production of probiotic yoghurt using l. paracasei ssp. tolerans, and evaluation of ph changes, viable counts, and organoleptic properties of the produced yoghurt. it was observed that the ph decrease during the fermentation period was faster in the milk inoculated with l. paracasei ssp. tolerans plus starter culture. there was a gradual decrease in ph in both ...

UV-C (254 nm)- and UV-B (280-320 nm)-light were irradiated onto bright-yellow capitula of dyer's saffron and their effects on carthamine accumulation compared. UV-C light promotes reddening of florets more prominently than UV-B light, yielding higher amounts of carthamine after the radiation process. The enhancement of carthamine synthesis by UV-C light was investigated on cellulose columns loa...

The main objective of this work was to assess the effectiveness of salicylic acid (SA), calcium chloride (CaCl2) or sodium bicarbonate (NaHCO3), and packaging on some qualitative properties of apricot fruit during cold storage. The experiments were conducted using a completely randomized design as factorial, with three replicates. Fruits were dipped in SA (0.1 or 0.5 mM), CaCl2 (1 or 2%) or NaH...

application of edible coatings to enhance storage life of fresh fruit has recently been under considerable attention. this experiment was conducted in order to explore the effect of chitosan coating and storage temperature on the postharvest life of pomegranate (punica granatum l.) fruit. therefore, pomegranate fruits ‘rabbab-e-neyriz’ were dipped in 0, 1 and 2% aqueous chitosan solutions, air ...

Baby mustard has increased in popularity among consumers. However, baby is highly perishable. In this study, the influence of various modified atmosphere packaging (MAP) on visual quality and content soluble sugars glucosinolates during postharvest storage was studied. packed no holes (M0), microholes (M1), or macroholes (M2) polyethylene bags respectively, then stored at 20 °C. M1 M2 inhibit d...

Freshly harvested white asparagus (Asparagus of®cinalis L.) spears (about 500 g per package) were over-wrapped with a 16 mm stretch ®lm. Packages were kept at 2.58C, 58C, 108C, 158C, 208C and 258C under continuous darkness or light (15 1.9 W mÿ2) for 6 days. At all temperatures, an atmosphere of 4.5±6.9% CO2 and 3±6.7% O2 developed during the ®rst hour; after 8 h, CO2 increased to a maximum of ...

the purpose of this study was to investigate the effect of polyvinyl chloride vacuum packaging(170 micron thickness) on omega 3 and omega 6 contents of carp fillet at -18 ° c during 180 day storage. the tests were done with the use of gas chromatography. total content of w6 in fresh fish was 18.21%. after 180 day storage the amount of w6 in control sample changed to 14.85% but for vacuumed fill...

the main postharvest problems of persimmon in iran are severe softening and disease incidence on the fruits during storage. therefore, delay in softening and/or control of diseases result in the storage life extension of persimmon fruit. the strategy of induced disease resistance in plants by biotic and abiotic treatments is an attractive method for controlling diseases. salicylic acid (sa) is ...
