title: In situ fermentation dynamics during production of gundruk and khalpi, ethnic fermented vegetable products of the Himalayas.
abstract: Gundruk is a fermented leafy vegetable and khalpi is a fermented cucumber product, prepared and consumed in the Himalayas. In situ fermentation dynamics during production of gundruk and khalpi was studied. Significant increase in population of lactic acid bacteria (LAB) was found during first few days of gundruk and khlapi fermentation, respectively. Gundruk fermentation was initiated by Lactobacillus brevis, Pediococcus pentosaceus and finally dominated by Lb. plantarum. Similarly in khalpi fermentation, heterofermentative LAB such as Leuconostoc fallax, Lb. brevis and P. pentosaceus initiated the fermentation and finally completed by Lb. plantarum. Attempts were made to produce gundruk and khalpi using mixed starter culture of LAB previously isolated from respective products. Both the products prepared under lab condition had scored higher sensory-rankings comparable to market products.
