稻米油不仅富含不饱和脂肪酸,还富含谷维素、植物甾醇等多种脂质伴随物,对人体健康十分有益。随着大健康产业的快速发展,稻米油的提质制取及高值化利用已成为大型油脂加工企业及科研者研究的热点。综述了稻米油中不饱和脂肪酸、谷维素、植物甾醇、角鲨烯、维生素E等营养成分的含量及功能,并对米糠稳定化处理、稻米油制取工艺及稻米油在煎炸食品、乳液递送、生物能源等方面的应用进行了梳理,旨在为稻米油的加工利用提供一定的理论基础及技术指导。 相似文献

米糠是稻米加工的重要副产物,过去常被人们所忽视导致利用率不高。随着近些年来对米糠研究的深入,研究人员逐渐意识到了米糠的营养价值,米糠富含维生素E、谷维素等营养物质,可以用于进一步生产米糠油。米糠中脂肪酶的存在导致米糠快速酸败是限制其进一步加工利用的主要原因,近些年国内外学者提出了多种稳定化米糠的方法,但是许多方法会破坏米糠中的营养成分或者稳定化的效果不佳,故对米糠中脂肪酶的性质及作用机制的研究是一个新思路。本文对米糠及其产物的营养价值、米糠稳定化及脂肪酶的研究进展进行概述,旨在为米糠研究和抑制米糠的酸败提供参考,为米糠的综合利用提供借鉴。 相似文献

Rice Bran: A Novel Functional Ingredient 总被引:3,自引:0,他引:3

Rice (Oryza sativa) is the most important staple food for a large part of the world's human population, especially in East and South Asia, the Middle East, Latin America, and the West Indies. It provides more than one fifth of the calories consumed worldwide by the human. It is the second leading cereal crop and staple food of half of the world's population. It is grown in at least 114 countries with global production of 645 million tons; share of Asian farmers is about 90% of the total produce. Rice bran, brown outer layer of rice kernel, is mainly composed of pericarp, aleurone, subaleurone layer, and germ. It contains appreciable quantities of nutrients like protein, fat, and dietary fiber. Furthermore, it contains substantial amount of minerals like K, Ca, Mg, and Fe. Presence of antioxidants like tocopherols, tocotrienols, and γ-oryzanol also brighten prospects of rice bran utilization for humans as functional ingredient to mitigate the life-threatening disorders. Moreover, in the developing countries, budding dilemma of food crisis, arising due to lower crop yields and escalating population, needs to utilize each pent of available resources. To provide enough food to all people, there is the holistic approach of using the by-products generated during food processing and preparations. Rice is being processed in well-established industry, but the major apprehension is the utilization of its by-products; rice bran (5–8%) and polishing (2–3%) that are going as waste. Rice processing or milling produces several streams of materials including milled rice, bran, and husk. In developing countries, rice bran is considered as a by-product of the milling process and commonly used in animal feed or discarded as a waste. The potential of producing rice bran at the global level is 29.3 million tons annually, whereas the share of Pakistan is worked out to be 0.5 million tons. In present paper, attempt has been made to highlight the significance of these valuable but neglected ingredients under various headings. 相似文献

Obesity and chronic diet‐related diseases such as type 2 diabetes, hypertension, cardiovascular disease, cancers, and celiac are increasing worldwide. The increasing prevalence of these diseases has led nutritionists and food scientists to pay more attention to the relationship between diet and different disease risks. Among different foods, rice has received increasing attention because it is a major component of billions of peoples’ diets throughout the world. Rice is commonly consumed after polishing or whitening and the polished grain is known a high glycemic food because of its high starch content. In addition, the removal of the outer bran layer during rice milling results in a loss of nutrients, dietary fiber, and bioactive components. Therefore, many studies were performed to investigate the potential health benefits for the consumption of whole brown rice (BR) grain in comparison to the milled or white rice (WR). The objective of this work was to review the recent advances in research performed for purposes of evaluation of nutritional value and potential health benefits of the whole BR grain. Studies carried out for purposes of developing BR‐based food products are reviewed. BR safety and preservation treatments are also explored. In addition, economic and environmental benefits for the consumption of whole BR instead of the polished or WR are presented. Furthermore, challenges facing the commercialization of BR and future perspectives to promote its utilization as food are discussed. 相似文献
