The objective of this study was to evaluate, from a technological and nutritional point of view, the chemical composition and functional properties of the industrial winemaking by-products, namely skins, stems and lees. The chemical and physical characteristics, as well as the functional properties (fat and water retention and swelling capacity, antioxidant capacity, and their prebiotic effect), of the dietary fibre of these by-products were studied. The results showed that the skins, stems, and lees are rich in fibre, with the stem fibre containing the highest amounts of non-extractable polyphenols attached to polysaccharides with high antioxidant activity and prebiotic effect. Lee fibre had the highest water retention capacity and oil retention capacity. The results reveal that winemaking by-products could be used as a source of dietary fibre with functional characteristics for food applications.

Nutrition Policies

The remarkable increase over the past 40 years in some chronic diseases, including the metabolic syndrome, has increased the demand for government and international policies to encourage various approaches to decrease the risk of these diseases. There are some prerequisites for working out successful national food and nutrition policies. Firstly, it is necessary to have a clear picture of the dietary pattern in a country and its associated public health problems. Based on these data, nutrient recommendations and goals are formulated by international or national scientific committees. Governments should translate these nutrient goals into food goals and eventually into national dietary guidelines. The means by which the national authorities can implement a nutrition policy include fortification and supplementation. Equally important are educational and informative tools, such as labelling on the packed food products including information about ingredients and nutrient content. With respect to the metabolic syndrome, this implies nutrient recommendations regarding the intake of fat and carbohydrates (energy per cent) and dietary fibre; dietary guidelines regarding balance between energy intake and expenditure; decreased consumption of products rich in fat and increased consumption of cereals and other products rich in dietary fibre, etc.; recommendations from the authorities regarding nutrient labelling (content of fat and dietary fibre) on relevant products; and nutrient and health claims and other aids (symbols) as tools to make it easier for consumers to select the appropriate food products.

In recent years, great interest has been focused on using natural antioxidants in food products, due to studies indicating possible adverse effects that may be related to the consumption of synthetic antioxidants. A variety of plant materials are known to be natural sources of antioxidants, such as herbs, spices, seeds, fruits and vegetables. The interest in these natural components is not only due to their biological value, but also to their economic impact, as most of them may be extracted from food by-products and under-exploited plant species. This article provides an overview of current knowledge on natural antioxidants: their sources, extraction methods and stabilization processes. In addition, recent studies on their applications in the food industry are also addressed; namely, as preservatives in different food products and in active films for packaging purposes and edible coatings.
