Walnut residue is a kind of high-quality plant protein resource. The bioactive peptide prepared from walnut residue has excellent health care functions such as antioxidation and antihypertensive activity, but at present, walnut residue is often regarded as waste or low value feed, fertilizer and other materials. The uneconomical use of walnut residue has hindered the development of the walnut industry to some extent. Effective utilization of walnut residue protein to develop bioactive peptides and other products is of great significance to realize the comprehensive utilization of walnut residue, improve the added value of by-products, and change the current low utilization rate of walnut residue. In this paper, the preparation, purification and structure identification of walnut protein bioactive peptides are reviewed, and different functional walnut active peptides (WBPs) are introduced. The potential effects of these bioactivities on human health and their different uses in food, medicine and other industries are discussed. The purpose is to provide reference information for the effective utilization of walnut residue resources and the development of walnut industry.
核桃残渣是一种优质的植物蛋白资源。从核桃残渣中制备的生物活性肽具有抗氧化和降血压等优异的保健功能，但目前，核桃残渣通常被视为废物或低值饲料、肥料等材料。核桃残渣的这种非经济利用在一定程度上阻碍了核桃产业的发展。有效利用核桃残渣蛋白开发生物活性肽等产品，对于实现核桃残渣的综合利用、提高副产品附加值以及改变当前核桃残渣利用率低的现状具有重要意义。本文综述了核桃蛋白生物活性肽的制备、纯化和结构鉴定，介绍了不同功能的核桃活性肽（WBPs），探讨了这些生物活性对人体健康的潜在影响及其在食品、医药等行业的不同用途，旨在为核桃残渣资源的有效利用和核桃产业的发展提供参考信息。
