Harvest and Post-harvest Operations
Harvest and post-harvest operations constitute principal constraints to rice production, especially in irrigated systems, because of the larger yield that has to be handled. Post-harvest crop losses of up to 35% have been reported and attributed to inefficiency of manual threshing of rice by small-scale farmers. This leads to poor grain quality and rejection of locally produced rice. The Africa...
متن کاملEffect of Pre-Harvest Calcium Chloride Spraying on Maintaining Fruit Bioactive Compounds and Antioxidant Capacity of Three Citrus Cultivars during Storage
Bioactive components play an important role in human health. In general, bioactive compounds of fruits decline during storage. Therefore, maintaining fruits bioactive compounds during storage is very important. In this study, effects of pre-harvest CaCl2 sprays (0, 1, 2, and 4%) at different fruit development stages (120, 140, and 160 days after full bloom) on maintaining fruit quality of thre...
متن کاملEffects of Genetic, Pre- and Post-Harvest Factors on Phenolic Content and Antioxidant Capacity of White Asparagus Spears
The effects of genetic, pre-harvest (season of harvest, spear diameter, spear portion and spear tip color) and post-harvest factors (storage and domestic preparation practices, e.g., peeling and cooking) on total phenolic, flavonoid and ascorbic acid content of white asparagus spears and their correlation with antioxidant capacity (DPPH and FRAP) were studied. Results showed that genetic materi...
متن کاملInvestigation of the tuber constituents of maca (Lepidium meyenii Walp.).
Lepidium meyenii, known in South America as maca, has received attention worldwide as a powerful energizer that improves physical and mental conditions and increases fertility. Because of these reports, we investigated the secondary metabolites of the tuber of maca. The methanol extract of the tuber of maca contained, in addition to free sugars and amino acids, the following: uridine, malic aci...
متن کاملHigh relative humidity pre-harvest reduces post-harvest proliferation of Salmonella in tomatoes.
Outbreaks of human illness caused by enteric pathogens such as Salmonella are increasingly linked to the consumption of fruits and vegetables. Knowledge on the factors affecting Salmonella proliferation on fresh produce therefore becomes increasingly important to safeguard public health. Previous experiments showed a limited impact of pre-harvest production practices on Salmonella proliferation...
