The in silico study was performed to predict the binding affinity of phytocompounds of C. grandis for α-amylase and α-glucosidase enzymes involved in the pathophysiology of diabetes with pharmacokinetic assessment. Response surface methodology was employed to determine the optimum values for TPC, TFC, TTC and antioxidant activities (DPPH and FRAP) across 17 separate experimental runs that varied microwave-assisted extraction parameters like temperature (50–70 °C), power (400–1000 W) and time (15-45 min). The purification and identification phytocompounds were done by column chromatography, TLC, UV-Visible, FTIR and LC-MS spectral analysis, respectively.

Candy is a popular confection worldwide, and it would be of societal benefit if it could be converted into a source of antioxidant molecules, to eliminate their adverse health effects. The amount of antioxidants available even in fruit candies is questionable due to the high thermal processing losses they undergo and the presence of various food additives. Plantains (Musa paradisiaca) are less known as good sources of biotherapeutic antioxidants, namely L-tryptophan, serotonin, and melatonin, and consumption of this highly nutritious fruit is limited to underdeveloped and developing countries. The objectives of this current study are: to develop a functional antioxidant-rich sugar-free plantain-based candy with appreciable contents of the mentioned biomolecules in synergy; and to ensure its extended shelf-life without compromising its physicochemical properties and functionalities by wrapping it with a suitable packaging laminate.\u0000Experimental approach. To accomplish the first objective, lyophilized plantain powder, sorbitol, and mannitol were used as base materials with minimal additives under minimal processing conditions to reduce processing losses. After development, the developed candies were evaluated for their sensory, proximate, physicochemical, and phytochemical properties, including the antioxidant synergy among the mentioned biomolecules. For the second objective, the candies were enclosed in two different flexible packaging laminates, and the optimal wrapper was determined based on the microbiological safety and sensory appeal of the packaged candies. Subsequently, the above-mentioned properties were assessed for the packaged (in the most suitable laminate) candies at regular time intervals during storage for assessment of their shelf-life. \u0000Results and conclusions. The candy exhibited a characteristic flavour of plantain, uniform dark brown colour, rich mouthfeel, pleasant aroma, moderately hard texture, and moderate sweetness, along with high antioxidant activity and considerable content of L-tryptophan, serotonin, and melatonin (present as a synergistic consortium). During storage of the packaged candy under ambient conditions, it remained microbiologically safe for up to 56 days, and also maintained sensory attributes, antioxidant potency, and synergy compared to the control candy. \u0000Novelty and scientific contribution.

While the use of chemical preservatives in meats may appear to be tremendously advantageous, they have long been purported to increase the risk of incidence of certain types of cancers. Consequentially, many persons have opted for minimally processed alternatives. This consumer shift has placed substantial pressure on the food industry to implement more natural alternatives to these synthetic preservatives in the meat industry. Research on plant extracts as potential agents for food additives is increasing. Considering the bioactive components present in West Indian bay leaf and turmeric essential oils, these oils present promising potential for their use as novel, green preservatives in the meat industry.\u0000Experimental approach. Raw chicken breast samples (28 g) were each treated with different doses (0.5 mL, 1 mL and 1.5 mL) of individual West Indian bay leaf and turmeric and a combination of the two essential oils (1:1 mixture of both oils to make up each of the 0.5 mL, 1 mL and 1.5 mL doses). Physicochemical, microbiological, and sensory evaluations were performed on the fresh and treated samples stored for 14 days at 4 ⁰C.\u0000Results and conclusions. The bay leaf oil exhibited a higher yield and total phenolic content while the turmeric oil had a higher total flavonoid content. The most effective treatments when compared to the control significantly (p<0.05) minimized the pH rise by 13.9 % (bay leaf oil 1.5 mL), reduced texture loss by 44.8 % (combination oil 1.5 mL) and reduced protein loss by 98.9 % (bay leaf oil 1 mL). Most treated samples exhibited reduced microbial loads, with the turmeric oil displaying highest efficacy against lactic acid bacteria, yeasts and moulds. Treated samples had significantly higher (p<0.05) final day sensory scores than the control, with the combination 1.5 mL dose proving to be the most effective, as the storage life of the chicken breast sample was extended by 6 days.\u0000Novelty and scientific contribution. This study has shown for the first time, that the essential oils from turmeric and West Indian bay leaf can extend the shelf life of raw chicken breast and highlights the potential of the oils as natural preservative agents in lieu of synthetic alternatives.","PeriodicalId":12400,"journal":{"name":"Food Technology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140379285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
