This study sought to reveal the mechanism of flavor generation when pomegranate seeds are processed, as well as the contribution of volatile organic components (VOCs) to flavor formation. Gas chromatography-ion mobility spectrometry (GC-IMS), combined with relative odor activity (ROAV) and statistical methods, was used for the analysis. The results showed that 54 compounds were identified from 70 peaks that appeared in the GC-IMS spectrum. Then, the ROAV results showed 17 key volatile components in processing pomegranate seeds, and 7 flavor components with large differential contributions were screened out using statistical methods. These included γ-butyrolactone, (E)-3-penten-2-one (dimer), pentanal, 1-propanethiol, octanal, and ethyl valerate (monomer). It is suggested that lipid oxidation and the Maillard reaction may be the main mechanisms of flavor formation during the processing of pomegranate seeds. Furthermore, this study lays the experimental and theoretical foundations for further research on the development of flavor products from pomegranate seeds.

The purpose of this study was to characterize unconventional cold-pressed seed oils (rosehip, strawberry, blackcurrant, carrot, plum, pomegranate, radish, and raspberry) as novel alternative edible oil source. A chemical characterization of different lipid components (total fatty acid composition, triacylglycerols, and vitamin E) and volatiles responsible for the particular aroma of these oils was reported. All the oils showed a content of unsaturated fatty acids, mainly oleic, linoleic, and α-linolenic acid, that potentially contribute to the prevention of cardiovascular diseases, in the range of 80%-90%.

Pomegranate seeds, a by-product of pomegranate processing, are gaining attention in food industries due to their high antioxidant activity. However, the lack of quality markers reflecting activity and spatial characteristics limits their utilization and product stability. In this research, a selective and sensitive method integrating ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry with feature-based molecular networking, and desorption electrospray ionization-mass spectrometry imaging developed to identify components and locate in-situ images of quality markers via spatial metabolomics analysis.

LN18178 is a standardized, synergistic combination of fruit rind and seed extracts, which has been reported to increase serum testosterone levels in young and aging males. The present 84-day randomized, double-blind, placebo-controlled study assessed the efficacy of LN18178 on the sexual function of aging male volunteers (age: 40-70 years; serum total testosterone: ≥ 300 ng/dL). The subjects with mild to moderate erectile dysfunction [5-item version of the International Index of Erectile Function (IIEF-5) scores 17-25] and low sexual desire (score < 3 on items 11 and 12 of IIEF) participated in this investigation.

Effect of fruit and cereal grain-based beverage studies on the lipid profile are limited. Pomegranate fruit and quinoa grains are known for their abundance of polyphenols with several health beneficial effects. The present study was carried out to investigate the effects of oral administration of beverage containing pomegranate juice and quinoa seed extract in obese rats.

Pomegranate ( L.) has long been recognised for its rich antioxidant profile and potential health benefits. Recent research has expanded its therapeutic potential to include antiangiogenic properties, which are crucial for inhibiting the growth of tumours and other pathological conditions involving aberrant blood vessel formation.
