一种新的卵性素食香肠,由小粉,白蛋白和大豆蛋白制成,表现出优越的物理化学和感官质量. 与现有的市场选择相比,这种创新的香肠配方实现了更高的消费者喜好和购买意图.
科学领域:
- 食品科学与技术 食品科学与技术
- 营养科学 营养科学
- 感官科学 感官科学
背景情况:
- 素食香肠市场正在增长,对产品的需求正在增长,这些产品提供了改善的营养特征和感官体验.
- 现有的素食香肠在组成和消费者接受方面各不相同,这凸显了对优化配方的需求.
- 与纯素食替代品相比,包含卵蛋白的ovo-vegetarian产品提供了独特的营养特征.
研究的目的:
- 评估一种新型的卵性素食香肠 (SO) 的物理化学和感官特性.
- 为了比较开发的SO与商业上可用的素食香肠 (SC,SH,SQ).
- 评估消费者对新型卵性素食香肠配方的喜好和购买意向.
主要方法:
- 物理化学分析包括蛋白质含量,pH值和颜色 (a*值).
- 感官分析:60-75个消费者的闪光体验,整体喜好和购买意图.
- 层次的多因素分析,以关联物理化学和感官数据.
主要成果:
- 与对照样本相比,开发的卵性素食香肠 (SO) 显示出明显更高的蛋白质含量,更低的pH值和更高的a*值 (p <0.05).
- SO是由诸如"弹性"",煮熟的玉米的味道"",特有的味道"",糕点"",柔软"和"棕色"等感官描述符的特征.
- SO表现出更大的整体喜欢和购买意图,与纹理和特定的感官属性有积极的相关性.
结论:
- 开发的卵性素食香肠 (SO) 具有增强的物理化学特性,特别是更高的蛋白质含量和有利的质地.
- 感官分析表明,由于其独特的风味和质地,消费者对SO有强烈的偏好.
- 物理化学特征,特别是质地和颜色,与消费者接受有积极的相关性,这表明它是营销素食香肠的可行替代品.
