Preservation potential and impact on product composition of peach processing technologies

Peach and peach products have been receiving increasing attention for production and?consumption in recent years due to their attractive appearance, good taste and nutritional value,?being good sources of many important phytochemicals with well-known bioactivities and health?benefits (e.g., carbohydrates ? fiber, vitamins, organic acids, phenolics, carotenoids, minerals,?etc.). Because of its seasonal, rather brief availability, varietal differences in maturity and fruit?composition, tissue sensitivity to physiological disorders (e.g. chilling injury), variation in flesh?texture and processing suitability, there is a growing interest among peach growers, scientists?and the processing industry to develop new products by exploring both conventional (e.g.,?canning, freezing, dehydration) and emerging technologies (e.g., ohmic heating, edible coatings and various minimal processing strategies involving high-pressure and other technologies), often?applied in a combined way, to improve preservation and end-product quality. Another issue less?well explored is the valorization of the by-products generated from the peach processing industry?which can become a valuable source of natural products. All these technological approaches?require optimization of processing parameters to maximize the nutritional and sensorial attributes?(texture, color, mouthfeel perception) as well as the development of an appropriate analytical?framework to monitor quality parameters for both product quality grading and assessing shelflife. This presentation will highlight some aspects of peach processing technologies, addressing their preservation potential and their impact on product compositional issues, sensorial attributes as well as retention of nutrients and other health important phytochemicals.
