Abstract

Castanea henryi (Ch) is an underexploited chestnut, has a higher starch content (47.58-56.94%) than other nuts (including C. mollissima, pine nuts, etc.) and is abundant in bioactive substances. Thus, Ch is expected to safeguard human health while relieving arable land pressure. However, there is a lack of a consolidated overview of health benefits and potential applications of Ch and its by-products. The Ch kernel is abundant in resistant starch (65.4% of starch) and polyphenols (1.03-1.07 mg/g), and has lipid-lowering, anti-diabetes, anti-inflammatory, and anti-cancer benefits, enabling it to develop functional products. Notably, severe kernel damage and browning deteriorate its quality during processing. In addition, numerous Ch by-products (such as shells, leaves, flowers, and wood) are often regarded as waste. However, Ch shells and leaves contain rich nutrients, such as polyphenols, flavonoids, proteins, and carbohydrates, which can directly produce functional products, plant substrates, and feedstuff. Meanwhile, the wasted Ch by-products can also indirectly produce some mushrooms, herbs, or animal products. This review integrates advanced knowledge on product development and processing of fleshy fruits, proposing innovative and practical strategies to achieve high-value utilization of Ch kernels and providing insights for the waste utilization of by-products, thereby unlocking their full industrial and health potential.

栗果循环经济：高价值利用与加工技术进步。

Castanea henryi （Ch）是一种未开发利用的栗子，淀粉含量（47.58 ~ 56.94%）高于其他坚果（包括C. mollissima、松子等），并含有丰富的生物活性物质。因此，中国有望在缓解耕地压力的同时保障人类健康。然而，缺乏对氯及其副产品的健康益处和潜在应用的综合概述。Ch核富含抗性淀粉（占淀粉的65.4%）和多酚（1.03-1.07 mg/g），具有降脂、抗糖尿病、抗炎、抗癌等功效，可开发功能性产品。值得注意的是，在加工过程中，严重的籽粒损伤和褐变使其品质恶化。此外，许多Ch的副产品（如贝壳、树叶、花和木材）通常被视为废物。然而，螺壳和叶片含有丰富的营养物质，如多酚、类黄酮、蛋白质和碳水化合物，可直接生产功能性产品、植物底物和饲料。同时，废弃的Ch副产品还可以间接生产一些蘑菇、草药或动物产品。本文整合了肉质水果产品开发和加工方面的先进知识，提出了创新和实用的策略来实现果仁的高价值利用，并为副产品的废物利用提供了见解，从而释放其充分的工业和健康潜力。

期刊介绍： Critical Reviews in Food Science and Nutrition serves as an authoritative outlet for critical perspectives on contemporary technology, food science, and human nutrition. With a specific focus on issues of national significance, particularly for food scientists, nutritionists, and health professionals, the journal delves into nutrition, functional foods, food safety, and food science and technology. Research areas span diverse topics such as diet and disease, antioxidants, allergenicity, microbiological concerns, flavor chemistry, nutrient roles and bioavailability, pesticides, toxic chemicals and regulation, risk assessment, food safety, and emerging food products, ingredients, and technologies.
