Spices and herbs are well appreciated for their medicinal properties since ancient times. Till date, spices are being explored for volatile oils (essential), flavour and for addressing many chronic diseases. In the present study, we investigated the physicochemical properties, fatty acid composition, differential scanning calorimetry (DSC), elemental composition and nutraceutical compounds of fixed oils (non-volatile) from five selected spices viz., , and . The fixed oil (FO) content of volatiles-free powders of the five selected spices ranged from 1.58% () to 26.43% (). The studied FO showed a good quality index which was analysed by estimation of free fatty acids, iodine value and unsaponifiable matter. The fatty acid analysis showed high palmitic acid in the FO of and . High linoleic, oleic, and myristic acid levels were observed in , and FOs, respectively. The nutraceutical compounds such as total phenolics were high in FO (0.53%). Hence the studied FO could be an excellent alternative to oil nutraceutical compounds. It may be used as a functional ingredient in foods which needs further validation for value addition.

Metabolic alterations, including hypermetabolism, lipid imbalances, and glucose dysregulation, are pivotal contributors to the onset and progression of Amyotrophic Lateral Sclerosis (ALS). These changes exacerbate systemic energy deficits, heighten oxidative stress, and fuel neuroinflammation. Simultaneously, gastrointestinal dysfunction and gut microbiota (GM) dysbiosis intensify disease pathology by driving immune dysregulation, compromising the intestinal barrier, and altering gut-brain axis (GBA) signaling, and lastly advancing neurodegeneration.

The importance of functional food's role in human nutrition as well as in the prevention of diseases, especially the treatment of chronic diseases like cancer, is an innovative field of research. Based on the studies regarding the antioxidant potential of oyster mushroom extract, it is evident that it has anticancer properties. The current article reviews the health benefits of edible oyster-mushroom-derived bioactive compounds, and how they specifically activate or regulate the immune system by affecting the maturation, differentiation, and proliferation of immune cells, thereby inhibiting cancer cell metastasis and growth.

In an era of escalating environmental challenges, converting organic residues into high-value bioactive compounds provides a sustainable way to reduce waste and enhance resource efficiency. This study explores the potential of the circular bioeconomy through the valorization of agricultural byproducts, with a focus on the antioxidant properties of specific chestnut burr cultivars. Currently, over one-third of food production is wasted, contributing to both humanitarian and environmental crises.

In the present study, we analyzed the bioactive curcuminoids content in eight capsules (DS-1-DS-7 and DS-9), one tablet (DS-8), three ground turmeric samples (DS-10-DS-12), and three ground turmeric rhizomes (TR-1, TR-2, and TR-3). Initial screening with infrared and ultraviolet-visible spectroscopy coupled with a principal component analysis (PCA) revealed distinct differences between the samples analyzed. Hence, targeted and untargeted analyses were performed using ultra-high-performance liquid chromatography and gas chromatography coupled with mass spectrometry detections.
