ABSTRACT

Background: Fermentation has been a crucial food processing technology for prolonging shelf life of food before refrigerators were invented and is still used but mostly in rural communities. It is however, mostly based on raw materials such as grains and starchy tubers. Not much is known about vegetable Fermentation in Nigeria. Objective: This study was aimed at investigating the effect of lactic acid fermentation in increasing the shelf life of vegetables. Methods: Fermented vegetables were cultured using the pore plate technique. Results: Lactic acid fermentation of vegetables most especially cabbages has been shown to be dominated by species of Lactobacillus, Leuconostoc, andin some cases Pediococcus. In this study, bacteria of the species Lactobacillus, Leuconostoc, Pediococcus, Streptococcus, Pseudomonas, Staphylococcus and Gluconobacterwere isolated from cabbage, carrots and tomatoes which had been shredded and packed in air tight jars for fermentation. A rapid decrease in pH coincided with a rapid increase in number of lactic acid bacteria and decrease in aerobic bacteria. The microbial load was found to vary between 1.6 x 106 and 3.0 x 108 for cabbage, 5.0 x 106 and 1.4 x 108 for carrots, 7.0 x 105 and 6.8 x 107 for tomatoes. Lactobacillus spp. had a close range of occurrence on all the vegetables which constitute 42.4%, 42.9% and 46.5% on cabbage, carrots and tomatoes respectively while Pediococcus spp. frequency include 23.6% and 20.2% on cabbage and carrots respectively and Staphylococcus spp. on the same vegetables include 1.2% and 5.5% respectively. However, Gluconobacter spp. constituting 8.5% was isolated on tomatoes only. Conclusion: it was evident that Lactic acid fermentation is a cheap way of increasing shelf-life and reducing pathogenic organisms in vegetables.
