The aim of this study was to determine the effects of Lactic Acid Bacteria (LAB) fermentation on the
texture and organic acid of pickled cucumbers. Texture and sensory evaluation as well as a microscopic observation
were performed to study the textural differences among fresh cucumber, Spontaneous fermentation (SF) cucumber
and LAB Inoculating Fermentation (LABIF) cucumber. Accumulation of seven organic acids i.e., oxalic, tartaric,
malic, lactic, acetic, citric and succinic acid during cucumber pickling were also studied. The disruption extent of the
middle lamella in SF cucumber displayed more obviously than that in LABIF cucumber, implying that LABIF
contributed to keep the cucumber original structure intact. Based on the organic acid accumulation pattern, in SF
LAB and Acetic Acid Bacteria (AAB) fermented simultaneously, while in LABIF LAB fermented beforehand thus
being in dominant position, then AAB fermented vigorously in a acidic condition created by LAB. The acetic acid
accumulaton pattern could be regarded as the distinctive feature between SF and LABIF. The orgnic acids produced
in LABIF were higher than that in SF. The final score of sensory evaluation combining texture analysis
demonstrated that LABIF overmatched SF. It was concluded that LABIF could obviously enhance the quality of
pickled cucumber and overwhelming SF, due to LABIF more beneficial to keep the cucumber original structure
intact and organic acids accumulation
