Physicochemical features, functional characteristics, and health benefits of cottonseed oil: a review

Abstract

Vegetable oils have their specific physicochemical properties due to which they are playing vital role in human nutritional diet for health benefits. Cottonseed oil is obtained from various species of cotton seeds that are famous to be grown mainly for their fiber quality. The most prominently used specie is Gossypium hirsutum. It is obvious that the seeds of different variety of cotton vary as grown in diverse agroclimatic conditions with respect to oil, fats and protein contents. Cottonseed oil is routinely used for cooking and food manufacturing products. Cottonseed oil obtained after proper extraction/processing steps from crude state to refined oil in a variety of ways. Cotton crop is considered for their dual-use purpose, for fiber quality and oil production to promote health benefits in the world. Keeping in view the above facts, this review clearly demonstrated an overview about physicochemical and functional properties of cottonseed oil to promote health benefits associated with the use of this oil. The overall characteristics and all concerned health benefits of CSO will further improve their usefulness is a compact way. We have summarized a brief multi-dimensional features of CSO in all aspects up to the best of our knowledge for the end researchers who can further research in the respective aspect.

The nutritional and industrial significance of cottonseeds and genetic techniques in gossypol detoxification

“…Cottonseed ranks fifth after soybean, palm, canola, and sunflower as a source of oilseed crops for protein (Zia et al, 2021). It is also a rich source of unsaturated fatty acids, with a 7:3 ratio to saturated fatty acids.…”

“…It is also a rich source of unsaturated fatty acids, with a 7:3 ratio to saturated fatty acids. Cottonseed oil (CSO) is also rich in oleic, linoleic, and linolenic acids (Zia et al, 2021), which benefit the healthy well‐being of humans. CSO alleviates the effects of cardiovascular diseases and has anticancer and antioxidant properties (Sekhar & Rao, 2011; Zia et al, 2021).…”

Besides its use as food, CSO is also a raw ingredient in the biofuel, lubricant, and hydraulic industries (Sinha & Murugavelh, 2016).…”

Identification and Functional Characterization of Acyl-ACP Thioesterases B (GhFatBs) Responsible for Palmitic Acid Accumulation in Cotton Seeds

“…Cotton ( Gossypium spp. ), an important cash crop around the world, not only produces high-quality fiber, but also provides a large amount of vegetable oil [ 1 ]. Cottonseed oil produced by traditional upland cotton occupies about 25% of the seed weight, with large yields because of the wide planting area [ 2 , 3 ].…”

“…Cottonseed oil produced by traditional upland cotton occupies about 25% of the seed weight, with large yields because of the wide planting area [ 2 , 3 ]. As an important resource of edible vegetable oil, cottonseed oil is commonly used in food products such as margarine, salad dressing foods and the deep frying of snack foods after removing toxic gossypol [ 1 ]. The major fatty acid components in cottonseed oil consist of palmitic acid (C16:0, ~25%), stearic acid (C18:0, ~2%), oleic acid (C18:1, ~15%), linoleic acid (C18:2, ~59%) and linolenic acid (C18:3, ~1.2%) [ 4 , 5 ].…”
