Description: Das Projekt "E 2: Fundamentals of tropical fruit processing with spectral reference to the maintenance of the essential compounds of fluid mango products" wird vom Umweltbundesamt gefördert und von Universität Hohenheim, Institut für Lebensmittelwissenschaft und Biotechnologie, Fachgebiet Lebensmittel pflanzlicher Herkunft (150d) durchgeführt. Depending on the altitude, mango and lychee cultivation, combined with soil conservation measures, can be used to tackle increasing soil degradation and subsequent loss of agricultural productivity in the mountainous areas of Northern Thailand. These fruits have a certain tradition in the area under investigation. For economic reasons they are presently mostly distributed as fresh fruits on local markets. Due to the limited availability of low-cost industrial fruit varieties, industrial processing of mangoes and lychees is restricted to the extremely short harvesting periods. Moreover, in Southeast Asia, where canning is still the most prevalent fruit processing technology, fruit purées and derived beverages can be considered as largely novel products. Serving as raw material for a broad variety of finished products (beverages, ice-cream, baby food and fruit preparations), fruit purée is understood as an important intermediate product not only on the export market but also on local markets in the long run. Intensified fruit production simultaneously requires a broad knowledge on the processing and nutritive properties of the fruit varieties under investigation and a detailed market analysis for the fruits and products derived thereof. In order to reduce fruit spoilage, scientific-technological as well as economic optimization of process technologies is required, based on the nutritive value of the raw material. The nutritive significance of both mangoes and lychees lies in their supply of important micronutrients. Due to their high beta-carotene content, mangoes can be regarded as a model for investigations on the stability of fat-soluble micronutrients, which are prone to degradation by oxidation and light. Lychees on the other hand are primarily a rich source of vitamin C, i.e. of water-soluble micronutrients in this context. With regard to the aim of the SFB, basic solutions for mango and lychee processing technologies which can also be realized in small- and medium-size companies are to be developed in E2. Research focuses on scientific evaluation and technological optimization of process technologies for fluid fruit products, aiming at a high micronutrient potential. Mango purée and nectar production is chosen as a model for studying micronutrient stability in hydrothermal processes. For the first time, alterations of carotenoids especially trans-cis-isomerization during technological processing will be investigated by means of stepwise process analyses. This will be compared to the stability of isolated reference compounds in order to study the effect of plant matrix on carotenoid stability. A particular feature of the project will be an economic evaluation of process technologies in close co-operation with subproject E3. For this purpose, processing costs and costs of development of processing innovations for purée and nectar production with a high micronutrient potential will be recorded. (abridged Text)
