![]() ![]() The obtained results suggested that evaluated citrus peel by-products could be reused as a source of polyphenols and transformed into value-added products. ![]() Furthermore, peel extracts were evaluated in terms of total polyphenol and flavonoid content, total antioxidant activity and DPPH free radical scavenging. lemon (11.6), grapefruit (18.9) or different orange varieties such as shamouti (29.5), clementine (29.8) and red. The most abundant polyphenol in the extracts obtained from all evaluated citrus samples was the flavanone hesperidin (280–673 mg Composition of Powdered Freeze-Dried Orange Juice Co-Product as Related to Glucose Absorption In Vitro. Narangin flavonoid was also identified in all samples, while rutin flavonol was determined in the concentration range of 3.3–4.7 mg Trans-Ferulic and p-coumaric antioxidants were found in lower quantities (<1.4 mg Dried Orange Peel can be used in your herbal tea blends, herbal bath mixtures, and savory and sweet recipes such as chutney, homemade bitters, and baked goods. Data were evaluated using multifactorial-ANOVA, response surface analysis and Principal Component Analysis. The effect of extraction variables on the recovery was examined by experimental factorial design. If you know me at all, you know that I used cardamom. Step 3: If you want to make the orange slices even sweeter, you can sprinkle the slices with some brown sugar and your favorite spices. LC-MS/MS was also employed for chemical profiling. Step 2: Arrange in a single layer on a baking sheet lined with parchment paper. A method combining solid-liquid extraction based on ethanolic aqueous solution, cLC-DAD and chemometrics, was performed to extract and quantify polyphenols from citrus peels.
