Abstract

Fermentation with lactic acid bacteria (LAB) offers a natural means to modify technological and nutritional properties of foods and food ingredients. This study explored the impact of fermentation with different exopolysaccharide (EPS) producing LAB on rheological, chemical and sensory properties of puréed carrots in water, as a vegetable model, with the focus on texture formation. The screening of 37 LAB strains for starter selection revealed 16 Lactobacillus, Leuconostoc and Weissella strains capable of EPS (dextran, levan, and/or β-glucan) production in the carrot raw material. Fermentations with five out of six selected EPS producers modified perceived texture of the liquid carrot model (p<0.05). The formation of low-branched dextran correlated with perceived thickness, whereas the production of β-glucan correlated with perceived elasticity. Low-branched dextran producing Weissella confusa and Leuconostoc lactis strains produced thick texture accompanied by pleasant odour and flavour. The fermentation with the selected EPS-producing LAB strains is a promising clean label approach to replace hydrocolloid additives as texturizers in vegetable containing products, not only carrot.

摘要

发酵利用乳酸菌(LAB)为改善食品和食品成分的技术和营养特性提供了一种自然的方法。本研究以蔬菜模型胡萝卜泥为研究对象,探讨了利用不同产胞外多糖(EPS)乳酸菌发酵对其在水中的流变性、化学和感官特性的影响,重点关注质地形成。通过对 37 株 LAB 菌株进行 starter 选择的筛选,发现有 16 株乳杆菌、肠膜明串珠菌和魏斯氏菌能够在胡萝卜原料中产生 EPS(葡聚糖、莱聚糖和/或β-葡聚糖)。六种选定的 EPS 生产者中的五种发酵改变了液体胡萝卜模型的感知质地(p<0.05)。低支链葡聚糖的形成与感知的厚度相关,而β-葡聚糖的产生与感知的弹性相关。产生低支链葡聚糖的魏斯氏菌和乳杆菌产生了稠度较高的质地,并伴有令人愉悦的气味和味道。利用选定的 EPS 产生 LAB 菌株发酵是一种很有前景的清洁标签方法,可以替代含有蔬菜产品中的水胶体添加剂作为增稠剂,而不仅仅是胡萝卜。
