Effects of sesame seed extract as a natural antioxidant on the oxidative stability of sunflower oil

Abstract

Natural and de-novo biosynthesized phyto-compounds have gained much significance because of their non-controversial nutritional, health and safety benefits as compared with chemically synthesized commercially rivalry antioxidants. However, none of natural de-novo biosynthesized phyto-compounds has been commercially available and used in customary food business and processing. In this study, efficacy of sesame seed extracts (SSEs) in stabilizing sunflower oil during storage has been studied. Fine powder of sesame seed was extracted in different solvents. The results showed that significant differences in extractability of different solvents and maximum extraction yield (29.48%) were achieved with methanol. The antioxidant components and capability of different extracts were further investigated and evaluated via total phenolic contents, DPPH radical scavenging activity and β-carotene/linoleic acid calorimetric assays respectively. Being highest in yield and antioxidant potential, methanolic extract was used; three different concentrations of SSE (500, 750, and 1000 μL) were added in 100 mL of sunflower oil to further evaluate its oxidative stability. Sensory and oxidative analysis of baked product from these groups was also evaluated.

Evaluation of antioxidant properties of the different tissues of vine tea (Ampelopsis grossedentata) in stripped canola oil and sunflower oil

“…Furthermore, the flavonoids have attracted widespread international attention for their easy availability and effective antioxidant capability. It has been reported that extracts of apple peel (Sekhon‐Loodu, Warnakulasuriya, Rupasinghe, & Shahidi, 2013), buckwheat hull (Hes et al., 2017), New Zealand seaweed (Kindleysides, Quek, & Miller, 2012), cinnamon extract (Zia et al., 2018), sesame seed (Hussain et al., 2018), and leaf of Ampelopsis grossedentata (Ye et al., 2015) exhibited the ability to preserve the oil quality after adding to the edible oil.…”

Efficacy of alkyltrimethylammonium bromide for decontaminating salt‐cured hides from the red heat causing moderately halophilic bacteria

“…3). different bioactive compounds in reducing halophilic bacterial population, which may be more cost-effective than ATMB, will be something that we would also like to explore in the future (Kumar and Singh 2015;Hameed et al 2017;Hussain et al 2018a;Hussain et al 2018b;Hussain et al 2018c). Particularly, the cocktail treated with 1000 and 5000 ppm ATMB resulted in 77% and 97% removal of selected halophilic bacteria respectively in SBS environment.…”

“…The optimized concentration may vary for the divergence of different animal hides or skins. Finally, the utilization of different bioactive compounds in reducing halophilic bacterial population, which may be more cost-effective than ATMB, will be something that we would also like to explore in the future (Kumar and Singh 2015;Hameed et al 2017;Hussain et al 2018a;Hussain et al 2018b;Hussain et al 2018c).…”

Antioxidant activity of sesame seed lignans in sunflower and flaxseed oils

“…Sesame oil is high in oleic and linoleic fatty acids which are unsaturated. In fact, sesame oil shows high oxidative stability presumably due to the indigenous antioxidants (Hussain et al, 2018).…”

“…Unfortunately, oils high in unsaturated fatty acids are susceptible to oxidation and can have short shelf lives without the use of an antioxidant. Sunflower oil is rich in mono and polyunsaturated fatty acids including oleic acid (14-40%) and linoleic acid (48-74%) (Hussain et al, 2018). Flaxseed oil is rich in polyunsaturated fatty acids and low in saturated fatty acids.…”
