Juice, Pulp and Seeds Fractionated from Dry Climate Primocane Raspberry Cultivars (Rubus idaeus) Have Significantly Different Antioxidant Capacity, Anthocyanin Content and Color

Abstract

Raspberries contain flavonoid antioxidants whose relative concentrations may vary between the juice, pulp, and seed fractions. Oxygen radical absorbance capacity (ORAC), total anthocyanin content, and berry color were determined for six cultivars of primocane raspberries grown in a dry climate (Utah, USA). Significant ORAC differences were found between juice (18.4 ± 0.39 μmol TE/g), pulp (24.45 ± 0.43), and seeds (273.27 ± 11.15) with all Utah cultivars combined. A significantly higher concentration of anthocyanins was present in Utah raspberry juice (20.86 ± 0.35 mg cyanidin-3-glucoside eq./100 g), compared to pulp (13.96 ± 0.35). Anthocyanin content of juice and pulp were significantly positively correlated with dark color (L*). This is the first report of fractional differences in dry climate raspberries, and has implications for the juice and supplement industries.

Antimicrobial effect and in vitro release of anthocyanins from berries and Roselle obtained via microencapsulation by spray drying

“…Studies by Wallace (2011) and Basu et al (2010) show the benefits of anthocyanins against cardiovascular diseases, cancer among others. Studies by Borges, Degeneve, Mullen, and Crozier (2010) and Snyder, Low, Stocks, Eggett, and Parker (2010) demonstrated that polyphenols, especially anthocyanins, have antimicrobial capacity. However, all these studies have been carried out on fresh fruits and juices, not on the microencapsulated powder of these compounds.…”

Formulation and evaluation of herbal sunscreen

“…It is the fixed oil yielded from the seeds of the Raspberry and its components are fatty acids, and high concentrations of vitamins A and E, so appreciated in the cosmetics and pharmaceutical industries. Its potentials that are high antioxidant capacity and exhibited anti-inflammatory, anti-aging, anti-mutagenic, and antimicrobial properties and also used as an efficient moisturizer and emollient which aids to alleviate oxidative stress in the skin, is utilized in cosmetic emulsions for UV protection [12,13]. It assists to protect cells from oxidative damage and also aids with maintaining the structure of the collagen [13].…”

Red Raspberry (Rubus idaeus L.) Seed Oil: A Review

“…RSO well-known for its components: fatty acids, vitamin E so appreciated in cosmetics and pharmaceuticals industries. RSO is also known for its high antioxidant capacity and exhibits anti-inflammatory, anti-mutagenic and antimicrobial properties [ 27 ]. RSO is also used in cosmetics as an efficient moisturizer and emollient which helps to reduce the oxidative stress in skin, is used in cosmetic emulsions for UV protection [ 6 ].…”
