摘要
核桃除鲜食之外,绝大部分被用于榨取核桃油,经过榨油工艺后所得副产物为核桃饼(粕),其中含有丰富的蛋白质、维生素、矿物质等人体所需的营养素,但目前核桃饼(粕)通常被用作食品加工配料或畜牧业饲料,深加工产品较少,加工程度及产品附加值较低。总结了核桃饼(粕)的主要营养成分及加工应用现状,分析发现其主要存在利用率低或加工成本昂贵等问题,而利用低成本手段提取核桃饼(粕)中的蛋白或将其直接合理加工则能改善这些问题,旨在为核桃饼(粕)的精深加工和核桃深加工产业链的延伸提供参考。
China has the largest area of walnut plantation and the highest output of walnuts in the world.In addition to fresh comcumption,the majority of walnuts are used for extracting walnut oil.Walnut cake(meal)is the by-product obtained from walnut oil extraction,which is abundant in essential nutrients such as protein,vitamins,and minerals required by the human body.However,despite its nutritional value,walnut cake(meal)is typically used as a food processing ingredient or livestock feed.Its utilization rate in further processing is low,resulting in limited deep-processing products and low added value.This paper summarizes the main nutrients components in walnut cake(meal)and its current processing and application status.The analysis reveals the challenges related to low utilization rates and high processing costs for walnut cake(meal).It suggests that utilizing cost-effective methods to extract protein from walnut cake(meal)or implementing rational direct processing can address these issues effectively.Ultimately,this paper serves as a theoretical foundation and technical guide for advancing the deep processing of walnut cake(meal)while extending the industrial chain for deep-processing walnuts.
