The article presents an analysis of the microflora of dried grapes with a description of the factors of influence. A technological method of processing dried grapes using ultrasonic action on plant raw materials is described. The fruits of dried grapes were investigated using different methods of pre-preparation - preliminary hydration of the fruits within 24 hours at a temperature of 20 ± 2 ° C. The dynamics of temperature changes during the processing of plant raw materials is analyzed. The indicators of microbiological safety of the products obtained from dried grapes were investigated. An analysis of the risk situation associated with the safety performance of ultrasonic treatment using the Fault Tree Analysis (FTA) method is presented. Situations that can lead to the occurrence of events in the production of products from dried grapes using technology based on the principles of ultrasonic exposure are analyzed.
The article presents the data of microbiological changes in the process of processing dried rose hips in water extraction using ultrasonic effects. Changes in safety indicators of various product samples with different parameters of pre-preparation of dried rose hips were investigated. The technological scheme of processing the used plant raw materials is presented. The microbiological indicators of the ultrasonic effect on the microflora of dried rosehip products are described. The results of the study of mechanically crushed dried rosehip fruit samples, hydrated and non-hydrated, are ambiguous. To analyze the risk of microbiological indicators, the “bow tie” method was used, the essence of the method was to display the risk, the sources of risk and all possible consequences associated with its occurrence were considered, as well as the display of risk mitigation measures depicted in one diagram.
Die thermische Kondensation von 1,2‐Dichlor‐ethylen (I) mit den Chlorsilanen (II), (VI) oder (X) in der Gasphase (Kontaktzeit 30 min) liefert je nach Reaktionstemperatur und Molverhältnis der reagierenden Stoffe verschiedene Produkte.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
