Summary: This study focused on the polyphenolic composition of Cistus creticus and six other Cistus species, finding differences in the chemical profiles which allowed for classification into two chemovariants. Plants with punicalagin derivatives and flavonol glycosides were abundant in the western Mediterranean, while those in Albania and eastwards had a nearly pure flavonol type. C. creticus showed a median antioxidative capacity of about half of the species with the highest antioxidative potential.

Summary: The effect of industrial drying processes on the phenols and polysaccharides of olive pomace and pomegranate peel was studied. It was found that the drying temperature had little effect on the polysaccharide fractions, and large-scale drying methods were effective in preventing the degradation of phenols.

Summary: This study found that pomegranate peel extract and its ellagitannin components synergistically modulate immune response by inhibiting cell proliferation and cytokine production. Additionally, pomegranate peel extract can stimulate the production of Treg cytokines, while the individual ellagitannin components do not have this effect. These findings contribute to a better understanding of the anti-inflammatory mechanism of pomegranate peel extract.

Summary: Pomegranate peel polyphenols, specifically punicalagin, have been studied for their antioxidant capacity and methods to protect and encapsulate them have been proposed. This study optimized the spray drying process of pomegranate peel polyphenols and evaluated their antioxidant activity for inhibiting lipid oxidation. The optimal conditions were determined and the polyphenols preserved their antioxidant capacity at a high percentage. The study suggests that spray dried pomegranate peel polyphenols can be used as antioxidants in edible oils.

Summary: Non-extractable polyphenols (NEPPs) in pomegranate peel were released using acid hydrolysis and ethyl acetate extraction, leading to the identification of ten NEPPs. Six compounds were isolated and their structures determined, with compounds 3 and 5 showing significant antimicrobial activity. This study sheds new light on the composition of bound chemicals in pomegranate peel and serves as a foundation for further processing and utilization.

Summary: This study aimed to chemico-biologically standardize Kaempferia galanga rhizome and investigate the vasorelaxation potential of its key phytochemical, ethyl-p-methoxycinnamate (EPMC). The results demonstrated that EPMC is responsible for vasorelaxation through endothelium-independent response mediated by Ca2+ dependent potassium channels. The study also developed a validated HPLC method for quality assessment of KGR, which allowed faster quantitation of EPMC and ethyl cinnamate compared to classical GC techniques.

Summary: This study used advanced chemometrics models to determine the influence of different extraction temperatures on the antioxidant profile and ellagitannins recovery of pomegranate peel extract. Extraction at 78 degrees Celsius showed the highest antioxidant activity and ellagitannins content. Pearson's bivariate correlation showed a strong positive correlation between ellagitannins and the anti-lipid peroxidative profile of the extract. The PCA and OPLS models adequately characterized and predicted the variation and patterns in the antioxidant and phytochemical datasets. OPLS biplot showed a distinct clustering pattern around 78 degrees Celsius extraction temperature, indicating the influence of ellagitannins on the antioxidant profile at this temperature.

Summary: In this study, a multi-objective optimization using response surface methodology was conducted to obtain pectin enriched in polyphenols from pomegranate peel. A green extraction technique combining citric acid and ultrasound was employed under optimized conditions: extraction time of 34.16 min, pH of 2.2, and temperature of 89.87 degrees C. The pectin obtained at the optimal point showed a yield of 31.89% and a total retained polyphenol content of 15.84 mg GAE/g pectin. Furthermore, the obtained pectin demonstrated similar properties to commercial pectin and showed potential as a high nutritional value ingredient or food supplement.

Summary: The pomegranate peel, a by-product of fruit waste, is rich in bioactive compounds such as ellagic acid. It has been found that ellagic acid and its metabolite urolithin B can form complexes with serum albumin, with urolithin B showing stronger binding force and more binding sites. The anti-cancer activity of ellagic acid and urolithin B is enhanced when combined with serum albumin.

Summary: Indigenous, underutilized fruits-byproducts, such as Harpephyllum caffrum Bernh peel extract (HCP), have the potential to be used as novel antioxidants in the food industry. This study evaluated the effects of different levels of purified ethanolic HCP extracts on the shelf life and sensory attributes of ground beef patties. The HCP extracts improved colour and protein stability, reduced TBARS levels, but also affected tenderness, juiciness, and flavours in the beef patties.

Summary: The implementation of artificial intelligence (AI) in postharvest agriculture has significantly improved thanks to extensive scientific research. This study used bibliometric tools to analyze research trends in AI application in postharvest agriculture, identifying research gaps and hotspots. The results showed a significant increase in publications on AI applications in postharvest agriculture research in the last decade. China, the USA, and India were the top three most productive countries in this field. The analysis also revealed low development degrees in certain topics such as the Internet of Things and cold chain logistics. This study contributes to reducing postharvest losses, enhancing food nutrition and quality, and mitigating food insecurity. It provides valuable scientific references for researchers and guides future research in AI applications in postharvest agriculture.
