Food production and processing in developing countries generate high levels of waste and byproducts, causing a negative environmental impact and significant expenses. However, these biomaterials have ample potential for generating food additives which in turn will minimize malnutrition and hunger in the developing countries where it is produced. Many of these biomaterials are a source of valuable compounds such as proteins, lipids, starch, micronutrients, bioactive compounds, and dietary fibers. Additionally, antinutritional factors present in some byproducts can be minimized through biotechnological processes for use as a food additive or in the formulation of balanced foods.

Juice productionVIDEO ON THE TOPIC: OLIVIM winery: initial processing of the grapes
It takes about 2. Pomace or grape marc , as grape waste is called, is something that the global wine industry produces a lot of — close to 12 million tons 11 million metric tons each year. So what do wineries do with all that gooey stuff?
You might think that disposing of vast quantities of it would be a sticky problem. But even though the liquid has been squeezed out, the material that's left behind has a variety of uses. As this article from Wine Maker magazine notes, the exact composition of pomace depends upon what sort of wine has been made and at what point the liquid was extracted.
With white wine, for example, the juice is removed prior to fermentation, so the pomace is rich in sugar, nitrogen and amino acids. With red wine, in which the grapes are fermented along with the juice before being pressed, there's less sugar and not as much of the tannins that give wine its bitter taste. But fermented pomace still contains a whole lot of different components, including cellulose, tartaric acid, trace amounts of other organic acids, sugars, tannins, plant pigments and some aromatic chemicals.
One way to get rid of all that pomace is to use it to make other types of alcoholic beverages. Pomace from white wine can be distilled to make grappa , a traditional Italian brandy.
Here's an article from Life in Italy about the history of that drink. Pomace also traditionally has been recycled as fertilizer or animal feed , but scientists are increasingly interested in studying ways of extracting useful components of grape marc for applications such as fuel alcohol production and biofuel energy production, and for the production of biosurfactants , which are used in environmental cleanups.
Food scientists have also realized that pomace contains a lot of healthy stuff — antioxidants, fiber and chemicals that help moderate blood sugar and create a feeling of fullness, to name a few — that can be used to make other foods healthier. Pomace has been used as an ingredient in bread, cereal, pasta, cheese, ice cream and even has been added to meat and seafood.
In northern California wine country, as this article from the Sonoma Press Democrat describes, some wineries use it to make cookies, flour and culinary oils. Is Homeowners Insurance Required? January 10, Kiger Mar 19, Grape pomace, or marc, is what's left over after the grapes are pressed in wine production. Some wineries use it as a fertilizing compost, while others are selling it to biogas companies for use as a renewable energy source.

Natural Bioactive Compounds from Winery By-Products as Health Promoters: A Review
Production of biodiesel from grape winery waste and fruit peels. The aim of this work is utilization of the grape pomace piled up as a waste after winemaking and its application in producing biodiesel. Furthermore, a novel yoghurt product was produced, enriched with antioxidants, such as polyphenolics from the grape pomace and berries in order to improve its nutritional value, contributing to food preservation and significantly reducing the risk of diseases. In fact, for the first time we engaged these compounds in preparation of a new yoghurt product, that proved to be last - longer and more beneficial for human health than the traditional one, since the antioxidants play a great role in the prevention of cardiovascular disease, cancer etc. Furthermore, a cost- effective, easily made and environmentally friendly biodiesel was produced, that could represent an alternative to the old fossil petroleum to replace it and resolve the present energy crisis. Totally, 4 types of Macedonian grape pomace, from Zupjanka, Prokupec, Kadinal and Vranec varieties as well as blueberry and aronia, were used.
The company processes 40 million litres of distillation wine and lees and more than , tonnes of grape marc at its sites in Nuriootpa, Berri and Griffith to ultimately produce about 10 million litres of grape spirit a year. Chief Executive Officer Jeremy Blanks said high-strength grape alcohol was a core product across a number of styles at Tarac including neutral grape spirit, brandy spirit, fortifying spirit, matured brandy and industrial spirit. Mr Blanks said Tarac offered these new producers a cost effective high quality base spirit that was consistent. Blanks said maintaining this consistency and distilling high quality clean spirit were keys to preserving a strong reputation.
This fact has led to a growing attention of suppliers on reuse of agro-industrial wastes rich in healthy plant ingredients. On this matter, grape has been pointed out as a rich source of bioactive compounds. Currently, up to million tons of grapes Vitis vinifera L. Winery wastes include biodegradable solids namely stems, skins, and seeds. Bioactive compounds from winery by-products have disclosed interesting health promoting activities both in vitro and in vivo. This is a comprehensive review on the phytochemicals present in winery by-products, extraction techniques, industrial uses, and biological activities demonstrated by their bioactive compounds concerning potential for human health. Grape crops are one of the main extended agro economic activities in the world with more than 60 million tons produced globally every year.
The intensification of the Vitis vinifera crop over recent decades has led to a continuous vineyard renewal, which has caused the disappearance of many indigenous minor grape varieties. Nevertheless, consumers today are looking for particular wines with enhanced varietal aroma. In fact, different landrace minor varieties have been recently authorized for winemaking in various Spanish Appellations of Origin AO ie.
Science Alert. Trends in Applied Sciences Research. Year: Volume: 14 Issue: 4 Page No. Abstract: Sheep farming is a prominent activity in Brazil and it provides the lower profit margins to the rural producer in extensive systems. Innovations in animal nutrition have shown alternative sources to improve the quality of food products. Grape pomace GP is a byproduct from winemaking used as feed for ruminants, with few studies on the quality of sheep meat. Thus, this study aimed to discuss the main characteristics of grape pomace, its relationship with the production, fatty acid profile and oxidative stability of sheep meat. The destination of GP as an agro-industrial residue is a concern in the winemaking industries, leading to the search for alternatives with low cost and high potential for use in animal feed. The GP is offered in various forms to animals, but the knowledge about its composition is required to explore its nutritional potential with no intoxication risks. Concerning the carcass characteristics , the productive performance of the animals can be favored with the use of GP in diet.

Grape juice concentrate is a controversial topic in winemaking. Most controversial of all is a substance called Mega Purple. This is supposedly frequently used in California to add colour to wines, as well as a little sweetness, and has caused quite a stir — perhaps, in part, because of the name. On a recent trip to California I got to see, for the first time, both regular grape juice concentrate, and also Mega Purple. A little bit of sugar rounds out the palate and adds to the perception of fruitiness. It also masks harsh tannins and covers over a bit of greenness. Mega Purple also adds a bit of sweetness, but is mainly used to add colour.
