Agricultural by-products of sesame are promising bioresources in food processing. This study extracted lignin from the by-products of sesame oil production, namely, the capsules and straw of black and white sesame. Using acid, alkali, and ethanol methods, 12 distinct lignins were obtained to prepare biochar, aiming to investigate both the structural characteristics of lignin-based biochar (LBB) and its ability to remove benzo[a]pyrene (BaP) from sesame oil. The results showed that white sesame straw was the most suitable raw material for preparing biochar. In terms of the preparation method, acid-extracted lignin biochar was more effective in removing BaP than alkaline or ethanol methods. Notably, WS-1LB (white sesame straw acid-extracted lignin biochar) exhibited the highest BaP adsorption efficiency (91.44 %) and the maximum specific surface area (1065.8187 m/g), characterized by porous structures. The pseudo 2 and Freundlich models were found to be the best fit for the adsorption kinetics and isotherms of BaP on LBB, respectively, suggesting that a multilayer adsorption process was dominant. The high adsorption of LBB mainly resulted from pore filling. This study provides an economical and highly efficient biochar adsorbent for the removal of BaP in oil.

Article Synopsis
  • The review analyzed randomized controlled trials (RCTs) to evaluate the effectiveness of topical sesame oil (SO) in preventing and managing infusion-related phlebitis (IRP), revealing inconsistent results in prior studies.
  • Eight studies, covering various patients with chemotherapy and amiodarone-induced phlebitis, showed that combining standard care with SO significantly reduced IRP symptoms compared to control treatments.
  • While the findings suggest that SO may positively impact IRP management, the quality of the evidence was moderate and highlighted the need for better study design and safety verification of sesame oil.

This study tackled mislabeling fraud in vegetable oils, driven by price disparities and profit motives, by developing an approach combining desorption electrospray ionization mass spectrometry (DESI-MS) with a shallow convolutional neural network (SCNN). The method was designed to characterize lipids and distinguish between nine vegetable oils: corn, soybean, peanut, sesame, rice bran, sunflower, camellia, olive, and walnut oils. The optimized DESI-MS method enhanced the ionization of non-polar glycerides and detected ion adducts like [TG + Na], [TG + NH].

Black oilseed crops are rich in diverse phenolic compounds and have excellent antioxidant activities, as reported in traditional Chinese medicine. Testa (seed coat) and peeled seeds (cotyledon, embryo, and other structures) are the seed's crucial components, contributing to the variation in phytonutrient, phenol content, bioactive component, and protective and pharmacological effects. However, comprehensive and comparative information on total phenol, flavonoid, antioxidant, and metabolic profiles in black seed testa and peeled sesame, soybean, peanut, and rapeseed seeds is rare.

Analog processed cheeses are cheese-like products with diverse compositions and functional properties that are produced by replacing milk components with non-milk components. The aim of the study was to investigate physicochemical, rheological and sensory properties of cheeses and oleogels. The results showed; that increasing the concentration of Mono and di-glyceride increased the oil binding capacity and improved the characteristics of the oleogel texture and stable during storage, especially in terms of oxidative.
