Abstract

This study valorizes red dragon fruit peel (an agro-industrial byproduct) as a useful ingredient in biscuits. Proximate analysis of the Red dragon fruit peel powder (RDFPP) revealed a high crude fiber (23.68 %), ash (10.60 %), and carbohydrates (43.32 %), along with bioactive components such as total phenolic content (0.34 mg GAE/g), flavonoids (53.32 mg QE/g) and antioxidant activity: 43.22 %). Fourier transform infrared spectroscopy identified functional groups associated with polysaccharides, phenolic content, flavonoids, and lipids in both peel and biscuits. Biscuits containing 0–9 % RDFPP were evaluated for physicochemical, bioactive, sensory, and microbiological qualities. Increasing RDFPP substitution increased ash (0.71 % to 2.27 %) and fiber (0.08 % to 0.74 %), while decreasing moisture (5.58 % to 4.21 %) and pH (5.34 to 5.03), enhancing shelf stability. Antioxidant activity and bioactive compounds increased proportionally, with 9 % RDFPP showing the highest values (total phenolic content: 0.50 mg GAE/g; total flavonoids: 1.99 ± 0.02 mg QE/g; DPPH: 38.79 %). Sensory evaluation indicated that 6 % RDFPP was the ideal acceptability level, after which color (darker, L*: 36.61) and taste declined due to betacyanin pigments and acidic significance. Scanning electron microscopy analysis revealed structural porosity at higher RDFPP levels, correlating with texture changes. Microbial shelf-life studies showed that RDFPP has antimicrobial properties, reducing bacterial growth in 9 % RDFPP biscuits (8.09 log₁₀ CFU/g) compared to the control (8.45 log₁₀ CFU/g) after 15 days. These findings highlighted the ability of RDFPP to enhance nutritional and functional properties of baked products. A 6 % RDFPP substitution optimized antioxidant enrichment, fiber fortification, and consumer acceptance, providing a sustainable solution for repurposing agricultural waste into value-added foods.

红龙果皮（Hylocereus polyrhizus）作为强化饼干功能成分的价值：理化、营养和感官意义

本研究验证了红龙果皮（农工副产品）在饼干中的应用价值。红龙果皮粉（RDFPP）具有较高的粗纤维（23.68%）、灰分（10.60%）和碳水化合物（43.32%）含量，以及总酚（0.34 mg GAE/g）、总黄酮（53.32 mg QE/g）和抗氧化活性（43.22%）等生物活性成分。傅里叶变换红外光谱鉴定了果皮和饼干中与多糖、酚类、类黄酮和脂类有关的官能团。对含有0 - 9% RDFPP的饼干的理化、生物活性、感官和微生物品质进行了评价。增加RDFPP取代量可提高灰分（0.71% ~ 2.27%）和纤维（0.08% ~ 0.74%），降低水分（5.58% ~ 4.21%）和pH(5.34 ~ 5.03)，提高货架稳定性。抗氧化活性和生物活性成分均以9%的RDFPP含量最高（总酚含量：0.50 mg GAE/g，总黄酮含量：1.99±0.02 mg QE/g， DPPH含量：38.79%）。感官评价表明，6%的RDFPP是理想的可接受水平，超过该水平后，由于β花青素色素和酸性显著性，颜色（较深，L*: 36.61）和味道下降。扫描电镜分析显示，较高RDFPP水平的结构孔隙率与织构变化有关。微生物保质期研究表明，RDFPP具有抗菌性能，15天后，9% RDFPP饼干（8.09 log10 CFU/g）的细菌生长比对照组（8.45 log10 CFU/g）减少。这些发现突出了RDFPP提高烘焙产品营养和功能特性的能力。6% RDFPP替代品优化了抗氧化剂富集、纤维强化和消费者接受度，为农业废弃物转化为增值食品提供了可持续的解决方案。
