Optimizing the Structural Integrity of Gwapyeon with Red BullⓇ and Enhancing Consumer Acceptability: A Comparison of Corn, Mung Bean, and Potato Starch

Gwapyeon, a traditional Korean fruit starch-based gel, offers a unique matrix for functional food diversifi-cation. This study investigated the technical feasibility of incorporating a commercial energy beverage (Red BullⓇ) into a gwapyeon system and evaluated how the source and concentration of plant-derived starch modulate its quality attributes. Corn, mung bean, and potato starch were utilized at 7%－11% under standard thermal processing conditions. The effects of the three starch parameters pH, soluble solids (Brix), chromaticity, syneresis during refrigeration, antioxidant capacity [total phenolic content (TPC), total flavonoid content, and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS)], and mechanical texture (texture profile analysis) were systematically analyzed, followed by a consumer (n=50) sensory evaluation. pH and Brix were not significantly affected by starch source or concentration, suggesting that they were primarily determined by the beverage-based matrix rather than starch formulation. Potato starch gels exhibited the greatest translucency and chromaticity (L*, a*, b*), whereas corn and mung bean starch produced more opaque matrices. Mung bean starch maintained superior network stability with minimal syneresis, while corn starch demonstrated higher initial moisture release followed by stabilization. Antioxidant retention (TPC and ABTS scavenging) was enhanced in corn and mung bean starch gels, likely due to entrapment within a denser network. Texturally, mung bean starch produced the firmest, most resilient gels, while potato starch yielded the softest. Sensory test results identified 9% corn starch formulation (RC9) as most favorable, balancing structural stability with moderate sweetness and chewiness. Starch is the primary determinant of structural and functional quality in beverage-incorporated gels, with corn starch being optimal for modernizing the traditional gwapyeon.

Lactiplantibacillus plantarum Q180 Mitigates Early High-Fat Diet-Induced Metabolic Dysfunction-Associated Steatotic Liver Disease by Modulating Gut-Liver Axis Inflammation and Barrier Integrity.

Metabolic dysfunction-associated steatotic liver disease (MASLD) develops through systemic metabolic dysregulation and gut-liver axis-mediated inflammation; however, effective preventive strategies remain limited. Probiotics such as Lactiplantibacillus plantarum have emerged as potential modulators of intestinal barrier integrity and hepatic inflammation; however, preventive efficacy during early MASLD progression has not been fully elucidated. The present study evaluated whether L. plantarum Q180 attenuates early high-fat diet (HFD)-induced MASLD in a murine model. Male C57BL/6J mice were fed a normal diet or 60% HFD for 12 weeks, and Q180 was orally administered at 1.0 × 109 CFU/day from weeks 5 to 12. HFD feeding induced obesity, hepatic lipid accumulation, and an elevated nonalcoholic fatty liver disease activity score (NAS), confirming early-stage MASLD. Although Q180 did not significantly reduce body weight gain or adipose tissue mass, Q180 did significantly decrease hepatic triglyceride levels and NAS, accompanied by improvements in steatosis, hepatocellular ballooning, and inflammatory infiltration. Hepatic expressions of Dgat1 and Sod were significantly upregulated, whereas Ldlr expression was downregulated. In the colon, Q180 markedly suppressed Tnf-α and Il-6 expression and partially restored Zo-1, Occludin, and Muc2 expressions. Serum endotoxin levels were significantly reduced, and a decreasing trend was observed in fecal endotoxin levels. Overall, Q180 exerted metabolic and immunological benefits during early MASLD progression by reducing hepatic lipid accumulation, enhancing antioxidant defenses, attenuating intestinal inflammation, reinforcing intestinal barrier integrity, and lowering endotoxin exposure. The results support Q180 as a promising probiotic candidate for the prevention and early management of MASLD through gut-liver axis modulation.
