Study Regarding the Production and Characterization of Rose Petal Jam Enriched with Saint John`s Wort (Hypericum Perforatum) Essential Oil

Abstract

The purpose of this study was to extract the volatile oil from St. John's wort and use it to obtain a new product with improved qualities and real health benefits. In order to characterize the innovative product, several physicochemical analyses were conducted (dry matter, ash content, total sugar, total acidity, vitamin C, flavonoid content and antioxidant capacity). Also the consumer perception was followed by conducting a sensory analysis. The study revealed that the adition of H. perforatum essential oil in the rose petal jam imporved the vitamin C and flavoinoid content and also the antioxidant capacity of the product, meanwhile the dry matter, ash content and total sugar determinations were normal for the free pectin jam category.

Preliminary Studies Regarding the Production of Jam from Organic Rose Petal

“…Aspect was pointed between 4.13 The results are according to other sensorial analysis regarding rose petals jam with very good appreciation from the target group (Youssef et al, 2012;Borș et al, 2014).…”

“…Some of the variants (V6, V7 and V10) are closer to the 1% essential oil enriched rose petal jam (Borș et al, 2014) with 30,15% dry matter. More variants are similar with the Baladi rose petal jam (Youssef et al, 2012) with a total dry matter between 20-25%.…”

“…From ancient times, roses were highly appreciated plant for its flowers, fruits, habitus, perfume and beauty (Australian Government, 2009; Youssef et al 2012; Borș et al, 2014). They became a symbol of love and victory, sign of nobility, refinement and profundity.…”
