Biochemical And Sensory Evaluations Of Turkish Delight (Lokum) Enriched With Black Grape And Sour Cherry Syrups, Ali̇ Batu, Ali̇ Arslan
Biochemical And Sensory Evaluations Of Turkish Delight (Lokum) Enriched With Black Grape And Sour Cherry Syrups, Ali̇ Batu, Ali̇ Arslan
Turkish Journal of Agriculture and Forestry
Black grape and sour cherry are high in phenolic substances and anthocyanin compounds, which are important for human health. Adding black grape and sour cherry fruit syrups into Turkish delight (lokum) could make the product healthier. While the highest antioxidant activity (AA) was found in the products produced with 7.5% black grape syrup (BGS) and sour cherry fruit syrup (SCS), the lowest AA was obtained from the control sample. The AA values of Turkish delight produced with BGS and SCS increased with the increased fruit concentration. Turkish delight produced with SCS had about twice as much AA than that produced …

The present study was carried out to determine the effects of methyl jasmonate (MeJA) treatments on the fruit peel color parameters, anthocyanin content, ethylene biosynthesis, phenolic content, and antioxidant capacity of Braeburn apples. Experimental trees were treated with 1120, 2240, or 4480 mg L-1 MeJA at 1- and 2-week intervals between the 105th and 175th days of growth after full bloom. L* and hue decreased linearly with increasing MeJA concentrations in both experimental years. While MeJA treatments did not cause significant changes in chroma, except for in the final harvest in 2010, it decreased chroma values significantly on all sampling …

This study aimed to determine the physicochemical properties of the green tea powders produced from 2 different Turkish tea [Camellia sinensis (L.) O.Kuntze] clones (Derepazarı 7 and Fener) grown under different shade levels and harvested during 2 consecutive shooting periods. Moisture, ash, crude fiber, and total phenolic contents of the green tea powders were determined based on the experimental factors. Products were also evaluated for their water activity, bulk density, particle size, color, extraction yield, and antioxidant activity. The shooting period, specific to Turkish tea cultivation, showed remarkable effects on the main quality parameters of the green tea powders. It …
