Mature leaves of kale and collard, and Brussels sprouts were heated by moist air at 40, 45, 50, or 55ºC for durations of 0, 30, 60, or 90 minutes. Heating of kale at 45 ºC for 30 minutes was effective in maintaining better postharvest quality, delaying yellowing, and reducing losses of sugars and organic acids during subsequent storage at 15 ºC. Exposure of collard at 40 ºC for 60 minutes also delayed yellowing and maintained turgidity of the leaves. Other treatments were either less beneficial, not effective, or caused injury.
Data on fresh fruit and vegetable shrink in supermarkets is important to help understand where and how much shrink could potentially be reduced by supermarkets to increase their profitability. This study provides: (1) shrink estimates for 24 fresh fruits and 31 fresh vegetables in U.S. supermarkets in 2011 and 2012; and (2) retail-level food loss.
This study was conducted on the effect of wrapping material and cold storage duration on plum (cv. Shablon) during cold storage at -1°C temperature and 98% relative humidity. Three wrapping materials (news paper + straw, kraft paper and kraft paper + straw) and five cold storage durations (0, 8, 16, 24 and 32-day) were investigated for some quality characteristics of plum including water content, total soluble solids (TSS) and firmness. The experiment was laid out in Factorial Completely Randomized Design (FCRD) with four replications for each one of factors.
Although considered a vegetable by most people, tomatoes are actually the fruit of several plants of the genus Lycopersicon. Tomatoes are one of the leading produce items in the United States in terms of value and volume consumes. Preserving the quality of the fruit from vine to consumer is essential to successful marketing. This fact sheet describes harvesting, handling, storage, and packaging procedures that will help maintain fruit quality. It also discusses the economic aspects of marketing the crop.
Although cooling increases production cost, it is essential to maintaining high product quality. No amount of cooling, however, will improve poor-quality produce. If you wish to have high-quality produce after cooling and storage, you must start with high-quality produce. Maintaining quality requires harvesting the crop at the correct stage of maturity; handling it with tender, loving care; and quickly cooling it to the proper storage temperature.
