Description: Das Projekt "E 2.2: Contributions of expanded raw material availability and waste utilization to sustainable fruit processing in the tropics and subtropics" wird vom Umweltbundesamt gefördert und von Universität Hohenheim, Institut für Lebensmittelwissenschaft und Biotechnologie, Fachgebiet Lebensmittel pflanzlicher Herkunft (150d) durchgeführt. Since the beginning of the Uplands Program in 2000, subproject E2 has been aimed at adjusted strategies for the utilization of mangoes, lychees and longans. The whole processing chain from fruit production through fruit processing to marketing has been studied in an interdisciplinary approach together with subprojects D1.1 (Fruit production) and E3.1 (Market potential) in Thailand. Various levels, such as raw material quality as well as technological and economic evaluation of fruit processing, have been investigated. In fruit processing, technological focus has been on fluid mango products. Continuation of E2 in phase 2 of the Uplands Program aims at sustainable food processing on two levels. Regarding quality profiles of raw fruits for fresh marketing or processing, quality and food safety aspects of fruits produced out of season is in the center of attention, since increased capacity utilization is expected due to increase or extension of harvesting periods per year, which should be based on ecologically compatible fruit production. Continuing research on mango processing, material circulation in food processing is intended by utilization of waste from fruit processing to recover by-products, especially pectins as gelling and stabilizing agents or bioactive fiber, prior to the use of residual waste as feed, thus reducing disposal problems and increasing added value by processing of the whole raw material into high-value main and by-products. Investigating the long-term effects of present and new off-season fruit production techniques applied by D1.1-2 (Alternate bearing) on fruit yield and quality in terms of appearance, basic components such as soluble solids, titratable acidity, vitamins and selected secondary plant metabolites (polyphenols), E2.2 is involved in the interdisciplinary research on the potential of off-season fruit production. Present public discussion on food safety, which is caused by increasing export problems due to exessive use of agrochemicals in Thailand, requires to test the effect of long-term application of paclobutrazol (PBZ) and KClO3. Both agrochemicals are presently used in root treatment of mango and longan trees, respectively, to induce flowering and off-season fruit production. Quantitative residue analyses in fruits will be performed by E2.2 applying GC-MS and HPLC. Conflicting reports on PBZ mobility in the plant support the need to prove the absence of non-tolerable PBZ residues in off-season mango fruits, thus strengthening the objective of D1.2 (Alternate bearing) in replacement of PBZ. Together with B2.2 (Agrochemical transport), residue analysis in the soil will be performed for the highly persistent triazolic plant growth regulator PBZ to monitor the impact of long-term application of PBZ on environmental risks in present off-season fruit production techniques over the period of phase 2.
