“…The pH of the water-oil matrix has been adjusted to be optimal, with pH = 3.8-4.2 of the Quara LowP and pH = 4.5-5.5 Lecitase Ultra supplied from Novozymes 18 . The enzymes react with the free form of (PC phosphatidylcholine, PI phosphatidylinositol, PE Phosphatidylethanolamine, and PA phosphatidic acid 39 , but the rate of the reaction varies from one phospholipid to another, for example, Ca, Mg, and Fe salts of PA are very slow and take from 4 to 6 h. After the reaction, the obtained oil with Quara LowP and Lecitase Ultra enzyme has low residual phosphorus < 10 mg/kg. The increment FFA in the treated oil measures enzymatic degumming process efficiency.…”

The vegetable oil degumming process plays a critical role in refining edible oil. Phospholipids (PL) removal from crude extracted soybean oil (SBO) by the enzymatic degumming process has been investigated in this work. Enzymatic degumming of extracted SBO with microbial phospholipase A1 PLA-1 Quara LowP and Lecitase Ultra enzymes have also been studied comparatively. The main novelty of our work is the use of the enzymatic degumming process on an industrial scale (600 tons a day). Many parameters have been discussed to understand in detail the factors affecting oil losses during the degumming process. The factors such as chemical conditioning (CC) by phosphoric acid 85%, the enzyme dosage mg/kg (feedstock dependent), the enzymatic degumming reaction time, and the characteristics of the plant-processed SBO have been discussed in detail. As a main point, the degummed oil with a phosphorus content of < 10 mg/kg increases yield. Quara LowP and Lecitase Ultra enzymes are not specific for certain phospholipids PL; however, the conversion rate depends on the SBO phospholipid composition. After 4 h, over 99% of Phospholipids were degraded to their lysophospholipid LPL (lysolecithin). The results showed a significant effect of operating parameters and characteristics of different origins of SBO, fatty acids FFA content, Phosphorus content and total divalent metals (Calcium Ca, Magnesium Mg and Iron Fe mg/kg) content on the oil loss. The benefit of using enzymatic degumming of vegetable oils rather than traditional chemical refining is that the enzymatic degumming process reduces total oil loss. This decrease is known as enzymatic yield. The enzymatic degumming also decreases wastewater and used chemicals and running costs; moreover, it enables physical refining by lowering the residue phosphorus to < 10 mg/kg.

“…Traditional water degumming, acid degumming, and alkaline degumming have either high oil losses or high residues of phospholipids. [ 42 ] Enzymatic degumming, a relatively new technology, effectively converts phosphatidylcholine and phosphatidylethanolamine into diacylglycerols. [ 39 ] It also has the benefit of reducing total oil loss and wastewater.…”

Corn oil is a major agricultural commodity, and it is a staple in kitchens worldwide. This comprehensive review aims to provide a holistic understanding of corn oil processing, composition, nutritional benefits, properties, and market dynamics. The processing of corn oil poses challenges in achieving optimal extraction efficiency while addressing environmental concerns. Currently, hexane‐extracted corn oil dominates the market, with cold‐pressed corn oil being a niche product. Ongoing efforts within the industry focus on exploring alternative, environmentally friendly extraction methods such as critical CO2 and enzymatic‐assisted extraction. Corn oil is recognized for its rich composition in monounsaturated and polyunsaturated fats, tocopherol content, and potential antioxidant benefits. However, its high omega‐6 fatty acid content, while contributing to its stability, has raised discussions about its potential impact on inflammatory responses when consumed excessively. Due to its high smoke point, corn oil is suitable for high‐temperature cooking without compromising its neutral taste. Yet, its oxidation stability is lower compared to other commercial oils. Relying on oleic‐rich varieties or incorporating antioxidants could help enhance its stability and mitigate potential oxidative concerns. In the future, advancements in processing technologies promise to elevate the nutritional profile of corn oil, aligning it with the evolving preferences of health‐conscious consumers and addressing sustainability concerns.Practical Applications. This review provides crucial insights into the processing, nutritional profile, and market dynamics of corn oil, benefiting researchers and industry professionals. By understanding the challenges and advancements in extraction methods, researchers can develop more sustainable and efficient processes. The detailed analysis of corn oil's composition and functionality provides practical solutions for improving product shelf‐life and quality. This comprehensive review supports the optimization of corn oil production and utilization and aids in positioning corn oil as a competitive and versatile option in the global vegetable oil market.

“…Several techniques exist and have been studied for bran stabilization: these include parboiling, chemical methods, stove toasting methods, ohmic heating techniques, retained moisture heating, added moisture heating, dry heating under atmospheric pressure, extrusion cooking, microwave heating, and infrared heating. Many researchers agree that the most effective of the aforementioned methods is microwave heating, an inexpensive and fast method that generates a product with a low range of free fatty acid that remains stable over time [4,[38][39][40]. After stabilization, rice bran can be employed directly or can be subjected to other processes in order to obtain high-value products for food, nutraceutical or pharmaceutical industry applications.…”

Rice is one of the most important crops throughout the world, as it contributes toward satisfying the food demand of much of the global population. It is well known that rice production generates a considerable number of by-products, among which rice bran deserves particular attention. This by-product is exceptionally rich in nutrients, since it contains a wide spectrum of macronutrients (proteins, fats, carbohydrates) as well as dietary fibers and bioactive compounds. However, rice bran is usually wasted or just used for the production of low-cost products. The lipidic fraction of rice bran contains an unsaponifiable fraction that is rich in such functional components as tocopherols, γ-oryzanol, tocotrienols, and phytosterols. This lipidic fraction can be extracted to obtain rice bran oil (RBO), a high value-added product with unique health properties as a result of its high concentration in γoryzanol, a powerful antioxidant mixture of bioactive molecules. Conventional extraction methods employ hexane as the solvent, but these methods suffer from some drawbacks linked to the toxicity of hexane for humans and the environment. The aim of the review presented herein is to point out the new green technologies currently applied for the extraction of RBO, by highlighting reliable alternatives to conventional solvent extraction methods that are in line with the twelve principles of green chemistry and a circular economy.
