Article Synopsis
- The study evaluates the bioactive compounds, antioxidant activity, and color parameters of jostaberry extracts from three drying methods: frozen, freeze-dried, and oven-dried.
- Non-conventional extraction methods like ultrasound and microwave are shown to better preserve anthocyanin content, while drying significantly reduces total anthocyanins and ascorbic acid levels.
- Results indicate that the frozen jostaberry extracts possess the highest antioxidant activity, and significant differences in antimicrobial effects were observed between the different pretreatment methods.
The article investigates the process of pectin extraction using ultrasonic and microwave techniques from apple pomace generated during juice production in the context of circular bioeconomy. The extraction yield, equivalent mass, content of methoxyl groups, content of anhydrogalacturonic acid, and degree of esterification of pectin were investigated. These indicators varied depending on the parameters and extraction method.
