概括
葡萄种子提取物与 Askorbic 酸结合,在香肠中表现出优异的抗氧化和抗菌作用,超过了合成抗氧化剂,并提供了更健康的食品替代品. 这种天然组合在干燥过程中显著改善了香肠的质量.
科学领域:
- 食品科学与技术 食品科学与技术
- 自然产品化学 自然产品化学
- 微生物学 微生物学
背景情况:
- 传统的香肠生产通常依赖于合成抗氧化剂和防腐剂.
- 人们对合成添加剂的健康影响和潜在毒性存在担忧,例如酸和酸.
- 天然抗氧化剂为改善食品质量和安全提供了一个有希望的替代品.
研究的目的:
- 为了评估天然抗氧化剂的有效性,包括葡萄种子提取物 (GSE), Askorbic 酸 (AA) 和α-托科菲罗尔 (TP),在干燥过程中的香肠.
- 为了比较天然抗氧化剂与合成抗氧化剂和传统配方的作用.
- 研究将GSE与AA或TP结合的协同效应.
主要方法:
- 使用传统的保加利亚卢卡卡配方制备香肠,添加各种天然抗氧化剂 (GSE,AA,TP,GSE+AA,GSE+TP) 并与对照组 (传统配方,合成抗氧化剂) 进行比较.
- 关键的质量参数包括pH值,水活性,颜色,脂质氧化 (MDA),抗氧化能力,总细菌数 (TBC),蛋白质含量和自由脂肪酸在整个干燥过程中都受到监测.
- 特别分析了GSE和AA之间的协同效应.
主要成果:
- GSE和AA的组合表现出最高的抗脂质潜力,最低的甲酸 (MDA) 值 (0.41 mg/kg) 和最高的抗菌能力 (TBC 78.50 × 10^3 cfu/g).
- 在干燥过程中,GSE+AA还导致颜色变化最小,抗氧化活性降低最低 (17.74%),表明有显著的协同效应.
- 葡萄提取物 (0.05%) 单独是第二最有效的;合成抗氧化剂和KNO3+AA产生了类似的结果,但KNO3显示有毒性. α-托科菲罗尔的效果不那么强.
结论:
- 葡萄种子提取物,特别是与 Askorbic 酸结合使用,在干燥过程中保持香肠质量方面非常有效.
- 像GSE+AA这样的天然抗氧化剂组合可以成功地取代合成抗氧化剂,提高香肠的质量和消费者的健康益处.
- GSE和AA之间的协同作用为改善加工肉类中的脂质氧化和微生物稳定性提供了一种强有力的自然解决方案.

Microbes in Food Production
Microbial fermentation is central to food biotechnology, enhancing flavor, texture, preservation, and stability. Fermentative microorganisms metabolize carbohydrates into organic acids, alcohols, and other metabolites that inhibit spoilage organisms and improve digestibility while contributing distinctive sensory qualities.In baking, amylases naturally present in flour hydrolyze starch into monosaccharides such as glucose, which Saccharomyces cerevisiae ferments anaerobically. Through...
Microbes in the Production of Fermented Foods
Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...
Microbial Spoilage of Food
Microbial food spoilage refers to the degradation of food quality resulting from the metabolic activity of microorganisms such as bacteria, yeasts, and molds. These microbes proliferate on various food substrates depending on factors such as moisture content, nutrient availability, and storage conditions, leading to undesirable sensory and structural changes.Bacteria are primary agents of spoilage in high-moisture, nutrient-dense foods like meat, milk, and vegetables. Microbial spoilage occurs...
