Назив: | The antioxidant activity of kombucha fermented milk products with stinging nettle and winter savory | Аутори: | Vitas, Jasmina Malbaša, Radomir Grahovac (Ranković), Jovana Lončar, Eva |
Датум издавања: | 5-апр-2013 | Издавач: | Belgrade: Association of the Chemical Engineers of Serbia | Часопис: | Chemical Industry and Chemical Engineering Quarterly | Сажетак: | This paper investigates the antioxidant activity of fermented milk products obtained by kombucha fermentation. Two starter cultures were used as follows: starter obtained after kombucha fermentation on sweetened stinging nettle extract, and starter obtained after kombucha fermentation on sweetened winter savory extract. The starters were added to milk with 0.8, 1.6 and 2.8% milk fat. Fermentation was carried out at 37, 40 and 43 °C and stopped when the pH reached 4.5. Antioxidant activity to hydroxyl and DPPH radicals was monitored using response surface methodology. Kombucha fermented milk products with stinging nettle (KSN) and with winter savory (KWS) showed the same antioxidant response to hydroxyl and different response to DPPH radicals. The synergetic effect of milk fat and fermentation temperature to antioxidant activity to hydroxyl radicals for both types of kombucha fermented milk products (KSN and KWS) was established. The optimum processing conditions in term of antioxidant activity were: milk fat around 2.8% and process temperature around 41 and 43 °C for KSN and KWS, respectively. | URI: | https://open.uns.ac.rs/handle/123456789/9008 | ISSN: | 14519372 | DOI: | 10.2298/CICEQ120205048V |
