In recent years, the recovery of valuable compounds from food waste like grape pomace is an emerging issue in the food sector. Grape pomace or marc can be considered as an important solid waste that is produced from the wine industries after the pressing and fermentation process. The waste produced from the wine industry causes pollution, difficulties in disposal/management, and also economic loss. Grape pomace consists of approximately 10%–30% of the crushed grape mass and other value-added products like unfermented sugars, polyphenols, pigments, alcohol, and tannins, etc. The recovery of these compounds by the most suitable and eco-friendly manner extraction techniques and able to maximize yield without compromising the stability/quality of the product is a challenging task. Grape pomace has greater potential values, there are technologies still to be developed and adopted in the winery and other associated industries. Since grape pomace is a natural plant product, it is rich in lignocellulosic compounds and could be used as a promising feedstock for the production of renewable energy. This review gives a brief overview of the extraction techniques like, Solid–Liquid Extraction, Supercritical Fluid Extraction, Accelerated Solvent Extraction, Microwave-Assisted Extraction, Enzyme Assisted Extraction, etc. Besides, the extraction of value-added products from the grape pomace and the biochemical and thermo-chemical management for recovery of energy, production of alcohol, fuel, and beverage, other novel products, and various applications such as environmental remediation and bio-surfactants are described briefly.

近年来，从食物残渣（如葡萄渣）中回收有价值的化合物是食品行业中的一个新兴问题。葡萄渣或果渣可被认为是葡萄酒行业经过压榨和发酵后产生的重要固体废物。葡萄酒行业产生的废物会造成污染，处置/管理困难以及经济损失。葡萄渣包含大约10％–30％的压碎葡萄块和其他增值产品，例如未发酵的糖，多酚，色素，酒精和单宁等。通过最合适且环境友好的方式回收这些化合物提取技术并能够在不损害产品稳定性/质量的前提下最大化产量是一项艰巨的任务。葡萄渣具有更大的潜在价值，在酿酒厂和其他相关行业中仍有待开发和采用的技术。由于葡萄渣是一种天然植物产品，因此富含木质纤维素化合物，可以用作生产可再生能源的有前途的原料。本文对固液萃取，超临界流体萃取，加速溶剂萃取，微波辅助萃取，酶辅助萃取等提取技术进行了简要概述。此外，还从葡萄渣和果渣中提取了增值产品。简要介绍了用于能源回收，酒精，燃料和饮料生产，其他新产品以及环境修复和生物表面活性剂等各种应用的生化和热化学管理。
