The growth of horticulture industries worldwide has generated huge quantities of fruit wastes (25%-40% of the total fruits processed). These residues are generally a good source of carbohydrates, especially cell wall polysaccharides and other functionally important bioactive molecules such as proteins, vitamins, minerals and natural antioxidants. "Apple pomace" is a left-over solid biomass with a high moisture content, obtained as a by-product during the processing of apple fruits for juice, cider or wine preparation. Owing to the high carbohydrate content, apple pomace is used as a substrate in a number of microbial processes for the production of organic acids, enzymes, single cell protein, ethanol, low alcoholic drinks and pigments. Recent research trends reveal that there is an increase in the utilization of apple pomace as a food processing residue for the extraction of value added products such as dietary fibre, protein, natural antioxidants, biopolymers, pigments and compounds with unique properties. However, the central dogma is still the stability, safety and economic feasibility of the process(s)/product(s) developed. This review is mainly focused on assessing recent research developments in extraction, isolation and characterization of bioactive molecules from apple pomace, along with their commercial utilization, in food fortification.

苹果渣加工生物活性分子。

全球园艺业的发展已产生了大量的水果废物（占加工水果总量的25％-40％）。这些残留物通常是碳水化合物的良好来源，尤其是细胞壁多糖和其他功能上重要的生物活性分子，例如蛋白质，维生素，矿物质和天然抗氧化剂。“苹果渣”是具有高水分含量的剩余固体生物质，是在苹果汁加工，苹果酒或葡萄酒制备过程中作为副产物获得的。由于碳水化合物含量高，苹果渣在许多微生物过程中被用作底物，用于生产有机酸，酶，单细胞蛋白，乙醇，低酒精饮料和色素。最近的研究趋势表明，苹果渣渣作为食品加工残渣用于提取增值产品（例如膳食纤维，蛋白质，天然抗氧化剂，生物聚合物，颜料和具有独特性质的化合物）的利用有所增加。然而，中心原则仍然是所开发的过程/产品的稳定性，安全性和经济可行性。这篇综述主要集中于评估苹果渣中生物活性分子的提取，分离和表征及其在食品强化中的商业利用方面的最新研究进展。开发的过程/产品的安全性和经济可行性。这篇综述主要集中于评估苹果渣中生物活性分子的提取，分离和表征及其在食品强化中的商业利用方面的最新研究进展。开发的过程/产品的安全性和经济可行性。这篇综述主要集中于评估苹果渣中生物活性分子的提取，分离和表征及其在食品强化中的商业利用方面的最新研究进展。
