Mountain animal food products are at the center of attention due to their intrinsic value and, as such, mountain beekeeping products deserve attention and effort for their valorisation. The work aimed at investigating the quality traits of mountain honey samples from Kyrgyzstan, giving particular emphasis on the amino acid profiles and their possible relationship with the other chemical-physical characteristics. The moisture content, acidity, pH, and diastase activity of honey samples were within the limits established by normative documents. The honey samples showed a higher diastase activity ...More
The fruit of sea-buckthorn (Hippophae rhamnoides L.) is a rich source of nutrients and phytochemicals. This study determined the chemical composition and antioxidant activity of sea-buckthorn grown in Issyk-Kul region, Kyrgyz Republic, during maturation from August to November. Three different assays [ferric reducing antioxidant power (FRAP), DPPH radical scavenging activity (DPPH), and cupric ion reducing antioxidant capacity (CUPRAC)] were used to determine the antioxidant activity of sea-buckthorn fruits. Sea-buckthorn fruits had a sugar content of 6.57-8.08 g/100g, a dietary fiber content ...More
A comparison study of the fermentation process of khainak (a hybrid of yak and cattle) and cow milk with commercial yoghurt (thermophilic), quark (mesophilic and mixed) starter cultures was conducted to find suitable starters using modern rheological, microbiological, and sensory methods. Lactic acid accumulation dynamic during the fermentation process of khainak milk with yoghurt starters was faster but did not differ from cow milk. The gel strength of the fermented khainak milk (206.3-447.2 Pa) was higher than that of cow milk (40-158 Pa). The total viable bacterial counts of all samples wer ...More
The suitability of mandarin (MP), orange (OP) and pomegranate peel powders (PP) for co-pigmentation of dewberry, viburnum, red hawthorn, black hawthorn, and barberry anthocyanins was investigated. Spectrophotometric measurements indicated co-pigmentation causing both a hyperchromic effect (Delta ABS(max) 5-13) and bathochromic shift (Delta lambda (vis-max) up to 13 nm). The degradation kinetics of anthocyanins were estimated at temperatures ranging from 70 to 90 degrees C. First-order reactions with rate constants of 0.45-2.93 min(-1) and 0.30-2.00 min(-1) were observed for the reference and P ...More
