Although not ideal, near - ripe high quality grape tomatoes perform well as components of fresh - cut vegetable trays

Grape and cherry tomatoes comprise about one quarter of retail tomato sales in the United States and are also important components in fresh - cut mixed vegetable trays. The latter require low temperature and some packaging which can produce a range of modified atmospheres (MAs) to achieve 14 days of shelf - life. Postharvest handling recommendations for good tomato quality do not usually include low temperatures or MA. Storage studies were conducted to ascertain the effect of low temperatures and MA on grape tomato quality. Grape tomatoes (orange - red or color stage 5) can be stored in clamshells up to 18 days at 5 C and still be of marketable quality if kept cold. Continuous storage at 5 C in air resulted in minimal weight loss (a significant cause of quality loss in grape tomato at warmer temperatures), no lycopene synthesis, decreased sugar concentrations, and retention of Vitamin C concentrations. However, if fruit were transferred from 5 or 10 C to warmer temperatures (i.e., 20 C), typical chilling injury symptoms (decay, poor color formation) occurred on fruit stored at 5 C but not at 10 C. Controlled atmospheres of 3 or 10% oxygen with 0, 7, 12 or 18% carbon dioxide provided little or no benefit, but were tolerated by grape tomatoes for up to 21 days at 5 C based on visual appearance, discoloration, decay, off - odors, flavor, and changes in concentrations of sugars, vitamin C, ethanol and acetaldehyde. Although not ideal, near - ripe high quality grape tomatoes perform well as components of fresh - cut vegetable trays at low temperature and under atmospheres not usually recommended for tomatoes.Original title and sourcesTOLERANCE OF GRAPE TOMATOES TO CONTROLLED ATMOSPHERES AT LOW TEMPERATURESCantwell, M.I. and Saltveit, M.E.(*) mesaltveit@ucdavis.eduDept.
