Food allergy to seeds is increasingly more common, with sesame being the most prevalent. Allergy to other seeds, including sunflower, pumpkin, poppy, mustard, and flaxseed, have been reported. Diagnosing a seed allergy is challenging, with many seeds being hidden additives in processed foods and cross-reactive testing. Food labels in the United States are now required to indicate the presence of sesame but other seeds are not required. Oral immunotherapy (OIT) protocols for peanut, milk, and egg are clinically being extrapolated to other foods, including sesame and sunflower seed...

Sesamol, a lignan, obtained from sesame seeds (Sesamum indicum Linn., Pedaliaciae) has a promising antioxidant, and anti-inflammatory profile. When applied topically, free sesamol rapidly crosses skin layers and gets absorbed in systemic circulation. Its encapsulation into solid lipid nanoparticles not only improved its localised delivery to skin but also resulted in better skin retention, as found in ex-vivo skin retention studies. Free and encapsulated sesamol was compared for antimicrobial and antibiofilm activity against some common skin pathogens and it was found that encapsulation improved the antimicrobial profile by 200%...

The study characterized the aroma-active compounds produced by sesame hulls at three roasting temperatures and analyzed the similarities and differences in the aroma profile of sesame hulls with whole seeds and kernels after roasting. Roasting hulls produced mainly furans, aldehydes, and ketones volatiles. 140 Compounds were identified as aroma-active compounds, including 36 key aroma compounds (odor activity value, OAV ≥ 1). Among them, furanone (caramel-like, OAV = 80), 3-methylbutanal (fruity, OAV = 124), and 2-methoxy-4-vinylphenol (burnt, smoky, OAV = 160) gave hulls (180 °C) sweet, burnt, and smoky aroma...

Fluorescence interference in Raman spectroscopy is a well-known problem and is especially significant in portable instruments where the availability of a variety of exciting wavelengths is unlikely. Several fluorescence avoidance and mitigation schemes are described in the literature, and implemented by Raman spectrometer manufacturers, but there is no standard method for evaluating the accuracy and repeatability of these schemes. Some test samples shown in instrument descriptions, such as "dark rum" and "sesame seed oil" are not reproducible...

Triacylglycerols (TAG), accumulate within lipid droplets (LD), predominantly surrounded by OLEOSINs (OLE), that protect TAG from hydrolysis. We tested the hypothesis that identifying and removing degradation signals from OLE would promote its abundance, preventing TAG degradation and enhancing TAG accumulation. We tested whether mutating potential ubiquitin-conjugation sites in a previously reported improved Sesamum indicum OLE (SiO) variant, o3-3 Cys-OLE (SiCO herein), would stabilize it and increase its lipogenic potential...
