This study aimed to evaluate the antioxidant activity of Argel leaf water extract (ALWE) and its effect at different concentrations (0, 5, 10, and 20 mg/100 mL) on the antioxidant, antimicrobial, physicochemical, and sensory attributes of chicken meatballs during cold storage. ALWE contained substantial quantities of total phenolic content (TPC), anthocyanin, and exhibited high DPPH scavenging activity. ALWE incorporation in chicken meatballs had a varying effect on the chemical composition and sensory attributes of the product. However, ALWE incorporation at high concentration decreased the protein content of cooked meatballs and reduced fat content in both raw and cooked balls. Increased ALWE concentration in chicken meatballs lowered the pH, microbial load, and thiobarbituric acid reactive substances. Furthermore, ALWE raised the TPC and DPPH scavenging activity of chicken meatballs. Throughout the storage period, chicken meatballs formulated with ALWE showed better quality attributes than non-formulated chicken meatballs. In conclusion, ALWE can be employed as a functional ingredient for improved health benefits and shelf-life extension of chicken meatballs.
本研究旨在评估阿尔吉尔叶水提取物(ALWE)的抗氧化活性及其在不同浓度(0、5、10和20毫克/100毫升)下对冷藏期间鸡肉丸子的抗氧化、抗菌、理化和感官特性的影响。ALWE含有大量的总酚含量(TPC)、花青素,并表现出高DPPH清除活性。将ALWE添加到鸡肉丸子中对产品的化学成分和感官特性有不同的影响。然而,高浓度添加ALWE会降低熟丸子的蛋白质含量,并降低生丸子和熟丸子中的脂肪含量。鸡肉丸子中ALWE浓度的增加降低了pH值、微生物负荷和硫代巴比妥酸反应性物质。此外,ALWE提高了鸡肉丸子的TPC和DPPH清除活性。在整个储存期内,添加ALWE的鸡肉丸子比未添加的鸡肉丸子表现出更好的品质特性。总之,ALWE可作为一种功能性成分,用于改善鸡肉丸子的健康益处并延长其保质期。
