Its pathogenesis is possibly linked to gut microbiota dysbiosis. This study investigates the preventive effects of chitosan self-assembled coconut residue dietary fiber (CRFSC) on hyperlipidemia induced by a high-fat diet (HFD) and gut microbiota. CRFSC resulted in a significant weight loss of 7.9% in HFD rats and had a preventive effect on all four lipid parameter abnormalities. HFD supplemented with oat group resulted in a weight loss of 3.8% in HFD rats and had no preventive effect on low-density lipoprotein cholesterol (LDL-C) abnormalities. Prevention was achieved not only through the modulation of gut microbiota composition and the increase of short-chain fatty acids (SCFAs) levels, but also through the activation of superoxide dismutase enzyme and the inhibition of malondialdehyde accumulation, all of which are the factors leading to the controlling of lipid abnormalities and oxidative damage. The prevention of lipid parameters by chitosan self-assembled coconut residue dietary fiber (CRFSC) may be attributed to its richness in chitosan and insoluble dietary fiber, as well as its ability to enrich beneficial bacteria such as Akkermansia, Roseburia, and Ruminococcus. Correlation analysis demonstrated that key bacterial species producing SCFAs, which are rich in the CRFSC diet, had a positive impact on controlling hyperlipidemia. Hence, consumption of a CRFSC diet could serve as an effective strategy for preventing and controlling the development of hyperlipidemia due to its potential ability to regulate gut microbiota and SCFAs. PRACTICAL APPLICATION: This study showed that dietary fiber from coconut residue after chitosan self-assembly had preventive effects on overweight, dyslipidemia, and oxidative damage in rats. In addition, CRFSC also increased the content of short-chain fatty acids in the gut. And improve gut health by affecting gut microbiota. This finding suggests that CRFSC can be used as a dietary strategy to prevent hyperlipidemia and has practical significance in developing new healthy foods.</p>","PeriodicalId":193,"journal":{"name":"Journal of Food Science","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142581531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The outer exine, composed of stress-resistant sporopollenin, and the inner intine, consisting of cellulose and pectin, form a barrier to digestive breakdown. This study investigates the potential of green techniques, specifically supercritical fluid extraction and ultrasonication, to disaggregate pollen cell walls, enhancing its bioavailability and maximizing nutrient utilization. Ultrasonication treated pollen (USTP) and supercritical fluid extraction-treated pollen (STP) demonstrated disruption, as evidenced by scanning electron microscopy imaging. In relation to scanning electron microscopy, techno-functional, antioxidant, and compositional analysis displayed a positive outcome, with crude lipid, protein, antioxidant activity (2,2-diphenyl-1-picrylhydrazyl activity and 2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid assay) and total phenolic content increased by 34.80%, 32.58%, 10.80%, 11.37%, and 83.94%, respectively. Based on the above properties, USTP for 4 h and STP at 400 bar for 40 min were identified as the optimal conditions for disintegration. Furthermore, optimized samples analyzed for amino acid and mineral release revealed a notable increase in composition of essential amino acid and minerals (Ca, Cu, Fe, etc.) by ∼1.5 and 1.2 times, respectively. Along with significant changes in composition, fractured pollen exhibited 1.4 folds increase in protein digestibility with minor differences in thermal stability, and crystallinity as established by differential scanning calorimetry, and X-ray diffraction analysis. The study confirms that nutrient release and absorption remain restricted without pre-treatment, highlighting the necessity of specific treatment to disintegrate bee pollen before its use as a functional food ingredient. PRACTICAL APPLICATION: Bee pollen is a rich source of all the essential nutrients required by the humans and recognised as a complete food. However, its tough cellular structure restricts its utilisation in numerous food applications. Therefore, to disintegrate bee pollen and release its nutrients, ultrasonication and super critical fluid extraction processes were employed to improve its utilization for human purposes.
