Evaluation of Microbiological Quality of Indigenous Dahi from Eastern Nepal

Abstract

The present study was undertaken to evaluate the microbiological quality of indigenous dahi from eastern Nepal. A total of 39 indigenous dahi samples were collected from sixteen districts of eastern Nepal and analyzed. Results revealed the mean yeasts and mould count to be 20.5×10 4 ±7503, coliform count 65±42, S. aureus197±65 and total viable bacterial count 227×10 6 ±17250 cfu/g. Total viable bacteria and yeasts and moulds were present in all samples examined. Coliforms were present in 90 % and S. aureus were present in 63% of samples examined whereas salmonella species were not detected in any of the samples under study.

Impact of type and level of stabilizers and fermentation period on the nutritional, microbiological, and sensory properties of short‐set Yoghurt

“…It is more nutritive than milk in terms of vitamin content, digestibility, and as a source of calcium and phosphorus (Foissy, 1983 ). It is believed that yoghurt has valuable “therapeutic properties” and helps in curing gastrointestinal disorders (Bhattarai and Das, 2016 ). It also prevents and controls diarrhea, can modulate the inflammatory response produced by carcinogens, and helps in reducing the inflammatory response through an increase in apoptosis.…”

Prevalence of migraine and tension‐type headache among undergraduate medical students of Kathmandu Valley: A cross‐sectional study

“…The burden of ill health and impaired quality of life due to headache remains large and it is estimated that it costs a minimum of US$100 million per million inhabitants per year 2 . In a domestic study within Nepal, headache was seen as one of the most prevalent painful conditions 5 …”

Evaluation of microbial quality and safety of selected dairy products with special focus on toxigenic genes of Bacillus cereus

“…Around the world, yogurt consumption with different flavours increased due to its excellent acceptable taste, balanced nutrients, and therapeutic value. Drinking yogurt is an elevating interest's level due to its appropriateness, easily carried, and advantages to human health (Olugbuyiro, 2011;Bhattarai and Das, 2016).…”
