A comprehensive review on processing, therapeutic benefits, challenges, and economic scenario of unconventional oils

Abstract

The review aims to focus on the processing and economic challenges of these oil industries (lack of organized cultivation, collection, processing, research, and market linking) and fetch the attention toward the application of green technology. The present article provides a systematic view to open a new sphere of understanding for unconventional oilseeds with its geographical distribution, chemical composition, health benefits, and research. Further, new sources of unconventional oil (cottonseed, rice bran, sal seed, mango kernel, etc.) may impart an alternative source of edible oil, which can fulfill the country's edible oil deficit with economic contribution. In inference, the combined evidence supports the assertion that unconventional sources of oils may provide an alternatives to major seed oils. Practical applications: Unconventional oils are the new boosting area to upthrust the production of edible oils and reduce the dependence of oil import from other countries. The emerging green technologies for oil extraction shall consider as high oil yield methods. There are many unconventional oil seeds which are still required to be the area for research and commercial application. The present article focused on the market scenario, health benefits of these oil seeds. � 2020 Wiley Periodicals LLC.
