Interpretive Summary: Consumption of red raspberries has steadily increased over the last decade in the US, partially due to the growing awareness of their potential health benefits of bioactive compounds including anthocyanins (ACNs). Processed red raspberries are frequently used in commercial applications. However, the information of ACNs in processed red raspberries is still scarce. In this study, ACN profiles and contents in 34 nationally representative common processed red raspberries (frozen, juice concentrate and puree) in the US market were investigated. The ACN were analyzed in a HPLC-MS system. Seven anthocyanins were identified and quantified, though individual samples contained 4 to 5 of them. The ACN profiles varied slightly but contents varied considerably among these samples, which may reflect the influences of environmental factors.

Technical Abstract: Consumption of red raspberries has steadily increased over the last decade in the US, partially due to the growing awareness of their potential health benefits of bioactive compounds including anthocyanins (ACNs). Processed red raspberries are frequently used in commercial applications. However, the information of ACNs in processed red raspberries is still scarce. In this study, ACN profiles and contents in 34 nationally representative common processed red raspberries (frozen, juice concentrate and puree) in the US market were investigated. The ACN were analyzed in a HPLC-MS system. Seven cyanidin or pelargonidin glycosides were identified and quantified, though individual samples contained 4 to 5 of them. Cyanidin-3-O-sophoroside and cyanidin-3-O-glucoside were the primary ACNs in all samples. The ACN profiles and contents varied within the same type of processed samples and between the different processed types. Five ACN profiles were observed in 18 frozen raspberry samples, and their total ACN contents ranged from 13.88 ± 1.21 to 38.43 ± 2.75 mg/100 g. Four raspberry juice concentrates were found to contain the same ACNs, and the total ACN contents ranged from 30.96 ± 5.34 to 65.29 ± 3.37 mg/100 g. Four ACN profiles were observed in 12 raspberry puree samples and their total ACN contents ranged from 10.89 ± 0.94 to 27.11 ± 1.15 mg/100 g. In conclusion, The ACN profiles varied slightly but contents varied considerably among these samples, which may reflect the influences of environmental factors.
