Production of Rice Bran Oil in India: a Technical Evaluation

India has the highest utilization of rice bran oil in terms of the available resources in the country.Parboiled rice tradition has made the available rice bran in relatively good quality.This makes the quality of crude rice bran oil being also high.Therefore the following processing is made relatively simple comparing with those high free fatty acid content crude rice bran oils.In India,physical refining is commonly used.Thus the oil refining yield is usually high.The unsaponifiable content is also higher comparatively.For example,oryzanol content is usually 1%to 1.5%in weight.Although there are a large number of rice bran oil small plants in India,the technology is relatively mature for the production of relatively good quality rice bran oil.In this short overview of the production technology of rice bran oil in India,the state of the art has been elaborated in a simple form.Particularly,the problems and challenges of the production technology have been evaluated with the background of decades of research and technology development work in India.

印度米糠油生产技术综述

相对其他国家,印度的米糠油是利用率比较高的。作为一个有食用蒸谷米传统的国家,印度可用于榨油的米糠质量相对较好,由米糠榨取得到的米糠原油的质量也很高。因此,与游离脂肪酸含量较高的米糠原油相比,印度米糠油的生产加工过程相对简单。印度主要采用物理精炼法精炼米糠油,精米糠油的产量一般较高。但相对而言,油中不皂化物的含量也很高。例如,谷维素的含量占精炼米糠油总质量通常为1%~5%,在印度尽管生产米糠油的大都是小型加工厂,但其生产相对高质量米糠油的技术已日趋成熟。概述印度米糠油的生产技术,并简述该领域的前沿技术。特别针对印度几十年的研究和技术开发工作,对米糠油生产技术目前存在的问题和面临的挑战进行评估。
