Impact of Rose Petal Antioxidants for Food Formulators : Challenges and Perspectives
Antioxidant compounds extracted from rose petals could protect the coulour of strawberry extracts during processing, says a recent study.
This research, published in the journal Innovative Food Science and Emerging Technologies and led by professor Kiril Mihalev from University of Food Technologies in Bulgaria try to look at natural alternatives to synthetic additives that could have significant implications for food formulators.
“The results obtained demonstrated that addition of polyphenolic co-pigments extracted from distilled rose petals reduced the thermal degradation of strawberry anthocianins, allowing improved colour stability of the processed strawberries”, claims the researcher team.
“This implies that fruit processing technology should orient itself in accordance with nature’s patterns, especially since more and more consumers reject the application of synthetic additives”, they added.
Palmen Mollov, Kiril Mihalev and colleagues look at the effects of using polyphenolic co-pigments extracted from rose petals (Rosa damascene Mill.) on the colour of strawberry pigments in a beverage that underwent a heat treatment.
The rose petal polyphenols were added to the strawberry beverage at a one to five ratio of total anthocyanins, with a total pigment concentration of approximately 0.0001 moles.
Addition of the rose petal polyphenols increased the colour stability of the beverage, particularly after prolonged heating (four hours), said the researchers.
“This polyphenolic fortification could be worthwhile not only from a technological point of view, but also with respect to the development of functional foods and beverages”, they said.
Professor Kiril Mihalev is invited at Paris Polyphenols 2012 World Congress which will be held in Paris, France in June 7-8, 2012, to present recent data and techniques concerning Rose Petal Polyphenols, their extraction, their benefits to valorize their use for pharmaceutical, cosmetic and food industries. In addition, a tailored Industrial Plateform & Network Session is organized during this congress. It’s the perfect occasion to discuss with industrials about Polyphenols Valorisation & Waste from Fruits and Vegetables Processing
