BACKGROUND Regular consumption of fruits and vegetables (e.g., tomatoes) has been shown to be beneficial in terms of reducing the incidence of cardiovascular diseases. The industrial processing of tomatoes into tomato-based products includes several thermal treatments. Very little is known on the effect of tomato industrial processing on antiaggregatory activity and phenolic profile. METHODS ...
The effects of temperature and calcium on pectin methylesterase (PME) activity and texture in tomato pericarp material were examined. Heating thin slices of pericarp to temperatures between 50 °C and 75 °C led to the rapid evolution of methanol from the material, indicating an activation of PME. This activity was further stimulated when CaCl2 (up to 2.0% w/v) was added. When applied to half-inc...
Salmonella remains a leading cause of bacterial food-borne disease, sickening millions each year. Although outbreaks of salmonellosis have traditionally been associated with contaminated meat products, recent years have seen numerous disease cases caused by the consumption of produce. Tomatoes have been specifically implicated, due to the ability of Salmonella spp. to enter the tomato fruit and...
The pollination effectiveness of the stingless bee Melipona quadrifasciata and the honey bee Apis mellifera was tested in tomato plots. The experiment was conducted in four greenhouses as well as in an external open plot in Ribeirão Preto, SP, Brazil. The tomato plants were exposed to visits by M. quadrifasciata in one greenhouse and to A. mellifera in another; two greenhouses were maintained w...
In this study, the effects of tomato (Solanum Lycopersicum cv. Depar F1) seedlings grafted on three different rootstocks (Kudret, Hamarat, Pençe) yield and some quality parameters plants grown in greenhouse open field were investigated. According to results we obtained, while greenhouses grew up 42.3% faster than those open, an increase was achieved by 265%. While TA vitamin C values, among fru...
Standard colour measurements can pose a serious problem for interpretation. For tomatoes the maturity at harvest does affect the colour that can maximally be obtained during postharvest storage. For more mature fruit up to 2 units (compared to 18 units tops) were found. This effect was ascribed to the level of a precursor produced during growth. More mature fruit also exhibit a more pronounced ...
