Abstract

The key parameters of raw material sanitation are the temperature and the time. These two factors can be seen as microbiological in sanitation processes because they are responsible for the elimination of microorganisms. The study object is represented by herbal substances of Calendula officinalis L. The material was dried in natural conditions and contaminated with yeast and mold fungi, colibacilli and aerobic bacteria. The reduction of bacterial content in dry herbal material was achieved by applying infrared radiation. The results show that the raw material made of Calendula officinalis flowers shall be heat-treated at temperatures of 70–80° with 30–60-second exposure and exposure rate of 7,5 kW/m2. Heating the calendula material up to 80° makes the extractive substance reduce by 10 % of the original value. If the exposure rate is at 2,5 and 5 kW/m2, the sanitation is not efficient. At the exposure rate of 7,5 kW/m2, the sanitation effect was achieved in three trials out of four. The results of the research show that the suggested energy-saving sanitation method allows reducing the microbial content of the contaminated herbal substance of Calendula officinalis til the normal level set out in the State Pharmacopoeia and the disease control authorities. It also allows for the production of medicinal substances of higher quality and optimum composition of extractive substances from 38,8 % (control value) to 35 % after the treatment.
