    Functional Potential of Sweet Cherry Cultivars Grown in New Zealand: Effects of Processing on Nutritional and Bioactive Properties
    (MDPI (Basel, Switzerland), 2025-11) Rashidinejad A; Ahmmed F; Lister C; Stoklosinski H; Wang Q; Wang Y
    While sweet cherries (Prunus avium L.) are globally recognized for their numerous potential health benefits, yet limited data exist on New Zealand-grown cultivars. This study examined the nutritional and bioactive profiles of six commercial cultivars—Kordia®, ‘Lapins’, Sweetheart®, Staccato®, ‘Bing’, and ‘Rainier’—in both fresh and processed (washed and packaged) forms. All cultivars contained notable levels of minerals, phenolics, and essential nutrients. Fresh cherries had higher mineral content (0.3–0.5 g/100 g) than processed ones (0.2–0.3 g/100 g). Carbohydrates ranged from 16.8 to 18.6 g/100 g in fresh and 15.1–17.5 g/100 g in processed cherries. Dietary fiber was slightly higher in processed samples (0.5–0.6 g/100 g) than fresh (0.2–0.5 g/100 g). Potassium, calcium, and phosphorus were more concentrated in fresh cherries. Major phenolic metabolites included neochlorogenic acid (up to 44.26 mg/100 g), (-)-epicatechin (7.89 mg/100 g), quercetin 3-rutinoside (4.34 mg/100 g), and cyanidin 3-rutinoside (80.42 mg/100 g). Processed ‘Lapins’ and ‘Bing’ retained high levels of neochlorogenic acid (40.98 and 44.26 mg/100 g), indicating minimal loss during processing. This study offers insights into the nutritional and bioactive composition of New Zealand-grown cherries, emphasizing their dietary value and health-promoting compounds such as polyphenols.

    Bioactive Yoghurt Containing Curcumin and Chlorogenic Acid Reduces Inflammation in Postmenopausal Women
    (MDPI (Basel, Switzerland), 2022-11-02) Ahmed Nasef N; Thota RN; Mutukumira AN; Rutherfurd-Markwick K; Dickens M; Gopal P; Singh H; Garg ML; Bordoni A
    Menopause is marked by a gradual and permanent decrease of estrogen from the ovaries, leading to metabolic and physiological changes in the body. Combined with increased body mass index, postmenopausal women have elevated systemic inflammation and metabolic disturbances leading to increased risk of developing chronic diseases. A bioactive coconut yoghurt containing curcumin and chlorogenic acid was developed with the potential to target inflammatory processes. In this randomized crossover study, healthy postmenopausal women with a BMI of 25-40 were recruited to consume 125 g of either the bioactive or placebo yoghurt. Blood samples were collected at baseline, 30 min, and 1, 2, 3 and 4 h postprandially. Plasma inflammatory markers (TNFα and IL6) and metabolic markers (triglycerides, insulin and glucose) were measured. Participants had significantly lower plasma TNFα Cmax after consumption of the bioactive yoghurt compared to placebo (mean difference = 0.3 pg/mL; p = 0.04). Additionally, plasma TNFα was significantly lower postprandially compared to baseline after consumption of the bioactive yogurt but not the placebo. No differences were observed in the metabolic markers measured. Conclusions: The bioactive yoghurt fortified with curcumin and chlorogenic acid has the potential to reduce inflammatory mediators; however, a larger and longer-term study is required to confirm these findings.
