• Isothermal crystallization of anhydrous milk fat by ultrasound. • The formation of β-crystals directly from the melt of sonicated samples. • The amount of monoacylglycerols is influenced by sonication.

• High intensity ultrasonic treated whey was used to form food systems with gel forming agents. • Gel former concentration can be reduced by 2 times compared to non-sonicated whey. • Ultrasonic treatment minimizes the set time for the gels up to 20% compared to the control. • Ultrasonic treatment within 15 min improves penetration pressure, hence the texture of the gel-like foods.

Flavonoids are plant polyphenols that exhibit biological activity with antibacterial, antiviral, antioxidant, anti-inflammatory, antimutagenic, and anticarcinogenic effects. The medicinal plants of Kuzbass have high contents of flavonoids and other polyphenolic compounds. Therefore, they can be used in medicinal preparations to prevent or treat serious diseases. We studied the following plants collected in Kuzbass: common thyme (Thymus vulgaris Linn., leaves and stems), woolly burdock (Arctium tomentosum Mill., roots), alfalfa (Medicago sativa L., leaves and stems), common lungwort (Pulmonaria officinalis L., leaves and stems), common yarrow (Achillea millefolium L., leaves and stems), red clover (Trifolium pratense L., leaves and stems), common ginseng (Panax ginseng, roots), sweetvetch (Hedysarum neglectum Ledeb., roots), and cow parsnip (Heracleum sibiricum L., inflorescences, leaves, and stems). To extract flavonoids, we used ethanol at concentrations of 40, 55, 60, 70, and 75%. Spectrophotometry was used to determine total flavonoids, while high-performance liquid chromatography was employed to study the qualitative and quantitative composition of the extracts. The highest yield of flavonoids was found in H. sibiricum leaves (at all concentrations except 70%), followed by the 55% and 70% ethanol extracts of T. vulgaris leaves and stems, as well as the 75% ethanol extract of A. millefolium leaves and stems. Thus, these plants have the greatest potential in being used in medicines. High-performance liquid chromatography showed the highest contents of polyphenolic compounds in the samples of P. officinalis, A. millefolium, T. vulgaris, and T. pratense. Our results can be used in further research to produce new medicinal preparations based on the medicinal plants of Kuzbass.

Обзор рисков контаминации антибиотиками молочной продукции

The article introduces a new systematic approach to product safety and quality. It relies on the measures of technological risk management based on the principles of Hazard Analysis and Critical Control Points (HACCP), qualimetric forecasting, and risk qualimetry. The stages and tools of risks identification, prediction, and analysis make it possible to detect faulty produce from field to market. The case study involved a line of flavored dairy products. The experiment demonstrated high efficiency in the field of risk management of safety and quality inconsistencies across the entire range of safety and quality requirements, including the sensory profile. The new approach provides a systematic solution to various safety and quality issues that every food-producing enterprise has to face.
