Enhancing oxidative stability of sunflower oil with sesame (Sesamum Indicum) coat ultrasonic extract rich in polyphenols

Phytochemical Profile and Antioxidant Activity of Sesame Seed (Sesamum indicum) By-Products for Stability and Shelf Life Improvement of Refined Olive Oil

“…A lower k value signifies that lipid rancidity is occurring at a slower rate. The results confirmed that sesame coats improved the oxidation resistance at high concentrations [14].…”

“…According to FAO statistics, the global production of sesame seeds is approximately 5.53 million metric tons, with Egypt producing approximately 40,000 tons in 2017 [ 13 ]. In Egypt, sesame is industrially processed to obtain different products, such as sesame oil, tahini, and tahini halva [ 14 ]. These products are widely consumed in the Middle East, Mediterranean, North Africa, USA, and Europe [ 15 ].…”

“…Sesame seed coats (SSCs) are by-products of tahini manufacturing or oil processing, including testae, bran, and hull [ 16 ]. The SSCs represent about 12% of the whole seed [ 14 ]. The SSCs are cheap, available, and generated in a large quantity [ 17 ].…”

“…Additionally, the phenolics have many health advantages, i.e., anti-inflammatory and anticancer [ 20 ]. The antioxidant impact of SSCs has been investigated in sunflower oil [ 14 ] and in macrophages [ 19 ]. One study by Mehdi et al [ 21 ] reported that the oxidative stability of sesame oil obtained from whole seeds was higher than those extracted from de-husked seeds.…”

“…One study by Mehdi et al [ 21 ] reported that the oxidative stability of sesame oil obtained from whole seeds was higher than those extracted from de-husked seeds. Another study by El-Roby, Hammad, and Galal [ 14 ] found that ethanolic extract of sesame seed coat has an antioxidant activity similar to tocopherol. Prakash et al [ 22 ] demonstrated that a black sesame coat had a higher antioxidant activity compared to a white sesame coat.…”
