The effect Leuconostoc mesenteroides and Lactobacillus plantarum has on the physical and chemical properties of fresh and dehydrated sauerkraut was tested. Sauerkraut inoculated with L . plantarum was slower in fermenting and significantly lower in acidity and higher in pH. Dehydration of sauerkraut by freeze-conventional hot-air and micro-wave processes produced a significant loss in volatile components, ascorbic acid , lactic acid and an increase in pH. Each of the dehydration processes caused browning of the sauerkraut . These changes were less with freeze-drying and increased with conventional hot-air drying and microwave drying. Gas-liquid chromatography confirms the loss of volatile components and the production of a new peak, occurring at 9 to 10 minutes , in the conventional hot-air dried and microwave dried. Sensory evaluation scores of freeze-dried and conventional hot-air dehydrated sauerkraut compared favorably with that of a canned commercial product.
