berangan banana were treated with hot water at 50 ºc for 0 (control), 10, and 20 min and then kept at room temperature (25±2 ºc), 75-80% rh to observe the ripening progress. firmness and activity of cell wall degradation enzymes such as polygalacturonase (pg), pectin methylesterase (pme), and pectate lyase (pl) were determined for treated and untreated banana. the microstructure of banana peel ...

the pomegranate fruits of cvs. malas yazdi and malas ashkezar were immersed in sa (1 and 2 mm from source of acytyl salicylic acid) for five minutes, in ja (0.3 and 0.4 mm from source of n-propyl dihydrojasmonate) for fifteen minutes, in cacl2 (1 and 2%) for five minutes, and in distilled water for five minutes as control. then, the fruits were stored in cold storage at 1.5±0.5ºc and 85±5% rela...

production of part-baked bread is a successful method to postpone bread staling that has been applied widely for production of loaves. in this research, production and some physical characteristics of part-baked flat bread (barbari) including hardness, volume, color, weight loss, and microstructure were studied during the storage of the samples at ambient (25ºc) and freezing (-18ºc) temperature...

in this research, a novel formulation of sponge cake was studied. instant tea powder (itp) with high ester-catechins content was used to replace 0, 7.5, 12.5, and 17.5% of flour to make sponge cakes, hereafter referred to as the control, itp1, itp2, and itp3, respectively. the microbiological analysis and lipid oxidation experiments were conducted and the odor, flavor, color, chewiness, and ove...

We examine the case of items with a limited shelf-life where storing an item (before consumption) may carry a cost to a buyer (or distributor). For example, eggs, milk, or Groupon coupons have a fixed expiry date, and seasonal goods can suffer a decrease in value. We show how this setting contrasts with recent results by Berbeglia et al [4] for items with infinite shelf-life. We prove tight bou...

Shelf life of fresh fruits and vegetables is greatly influenced by environmental conditions. Increasing temperature usually results in accelerated loss of quality and shelf-life reduction, which is not physically visible until too late in the supply chain to adjust logistics to match shelf life. A blackberry study showed that temperatures inside pallets varied significantly and 57% of the berri...

this paper deals with an i * corresponding author email address:   nventory system with one central warehouse and a number of identical retailers. we consider perishable-on-the-shelf items; that is, all items have a fixed shelf life and start to age on their arrival at the retailers. each retailer faces poisson demand and employs (1, t) inventory policy. although demand n...
