Food Security: Nutritional Characteristics, Feed Utilization Status and Limiting Factors of Aged Brown Rice

Abstract

Rice is one of the most significant food crops for human sustenance. Every year, many countries around the world hoard enormous amounts of rice to avert emergencies and guarantee food security and sufficiency. As a result, the inventory of aged rice is growing as the number of inventory years rises. Aged rice stored over three years loses its nutritional value and is no longer suitable for human consumption. There is a pressing need to find a solution to effectively utilize aged brown rice produced from aged rice after dehulling. Developing and utilizing aged brown rice as feed is economical and efficient due to its massive resources and rich nutritional content, which will also lessen food waste while resolving the problem of excessive hoarding of aged rice. This review mainly summarizes the nutritional value, application in feed, and nutritional limiting factors of aged brown rice. It provides a theoretical basis for solving the overstock of aged brown rice and the feasibility of using aged brown rice as feed in a cost-effective way.
