Most tropical horticultural commodities are sensitive to chilling temperatures. Therefore, chilling injury (CI) is a serious problem in the postharvest handling of tropical horticultural commodities. From the standpoint of CI, we can classify all horticultural crops into three categories: A) chilling resistant; B) chilling sensitive; and C) slightly chilling sensitive. The storage life of commo...

In this research, the survival of probiotic microorganisms in yogurts stored at room temperature (cold chain interruption conditions) was studied. Milk inoculated with yogurt bacteria (mixed culture of Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus) and a single probiotic culture (L. acidophilus LA-5 or Bifidobacterium lactis Bb-12 or L. rhamnosus HN001 or L. paracasei...

background and objectives: tree nuts and their oils contain bioactive materials which have vital roles in improving human’s health. degradation and decreasing the quality of the nuts especially in almond which have high fat is related to the oxidation. the quality of stored almond depends mainly on the kernel moisture and fat , storage temperature, relative humidity, oxygen level, type of packa...

Many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. Several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (ASF) of such systems. In this paper, the behaviour of integrating the phase change material (PCM) in SDHW systems is modelled and optimized n...

background and objective: prostate cancer is a prevalent disease around the world. the prostatic specific antigen (psa) test has recently proved itself as a useful method for the diagnosis and examination of patients with prostatic cancer. the objective of this study was to compare the stability of free psa and total psa in different storage settings. materials and methods: samples were obtaine...

the effects of different stages of maturity (mature green, until 20 to 40% of change in color), two treatments of cool water (5 ?c for 5' and 10 ?c for 15min.), two treatments of hot water (50 ?c for 15 min. and 55 ?c for 5 min.) ), two temperatures (10 and 14 °c) of storage vs. six time periods (0, 5, 10, 15, 20 and 25 days) on shelf life and storage time of ‘langra’ mango fruit were stud...

present study examined the effect of storage conditions (packaging type, storage temperature and time) on physicochemical and microbial properties of tomato juice. samples were stored for one and three months in two packaging types (bottle and doypack) at 4, 25 and 35oc. results obtained from testes (ph changes, acidity, solid soluble content, vitamin c content, and microbial load) showed that ...

pistachio nut is one of the most important export crops in iran. for prevention of rancidity and to ensure good quality, pistachio must be harvested in a short time and be prepared for drying in 24h.the ohadi variety of iranian raw dry pistachio nuts was selected for the experiments. instrumental hardness and sensory characteristics of pistachio nuts such as: flavor , texture and total acceptan...
