Quality Attributes of Fermented and Acidified Green Beans

A study was conducted with two styles and four blanch methods on green beans which were acidified with one of four organic acids or fermented. The beans were compared with conventional canned beans for selected quality attributes. Analyses showed that acidified and fermented beans were acceptable in color, firmness and flavor regardless of style, blanch or storage. The acidified and fermented beans were much firmer with less sloughing than conventional canned beans. Minor differences were noted in nutritive value of the beans. Panel ratings for flavor of acidified beans were not significantly different from the conventional canned beans except in fermented beans. Flavor differences in fermented beans were probably caused by flavor volatiles produced by the bacteria. Acidified and fermented beans should be suitable for many types of dishes prepared with green beans such as casseroles, salads, etc. as well as for salad bars.
