    Cocoa powder is an important dietary source of flavanols that modulate elevated blood pressure (BP). This study aimed to investigate the acute effects of cocoa beverage co-consumption with a high-fat-high-salt meal (HFHSM) on postprandial systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate in older adults living with uncontrolled hypertension. The study was a randomized crossover trial and involved older adults (aged 52.50 ± 9.36 years) (n = 28) living with hypertension. Participants, following an overnight fast, consumed either an HFHSM and cocoa beverage comprising 15 g cocoa powder in 250 mL water (HFHSM + CB; intervention) or HFHSM and 250 mL water (HFHSM + W; control). Resting SBP, DBP, and the heart rate of participants were measured at baseline (−5 min and 0 min) and 15, 30, 45, 60, 90, and 120 min following the consumption of either HFHSM + CB or HFHSM + W using an automated BP monitor. Repeated measures linear mixed model was used to compare the effect of cocoa beverage and water on postprandial outcomes over a 2-h period. A significant reduction (−3.8 ± 0.6 mmHg, p <.05) in resting SBP was observed postprandially following the intake of the HFHSM + CB over the 120-min period compared to the HFHSM + W. The effect was more prominent during the 90- and 120-min time points of the trial duration. No significant change in the DBP and heart rate following the consumption of HFHSM + CB compared to the HFHSM + W was observed. Cocoa beverage co-consumption with HFHSM improved postprandial SBP in older adults living with hypertension.

    Cocoa bean shell (CBS) remains a commonly produced by-product of cocoa bean processing. It is usually obtained from fermented and dried cocoa beans that are roasted. The study investigated the potential use of Near-infrared spectroscopy (NIRS) analysis for discriminating roasted and unroasted CBS among cocoa clones and quantifying some nutritional and bioactive components in Ghana. Five clones, comprising four important seed gardens clones used across West Africa and one criollo were evaluated. Cocoa beans from the different clones (T60/887, VENC 4, MO 20, PA 150 and T60/887 × POUND 7) were divided into two parts, with one part roasted at a temperature of 120 °C for 50 min while the other part was kept unroasted. The CBSs were milled and passed through a 425 μm pore-sized sieve to obtain the powder. A handheld portable NIRS was used to scan the CBS powder in Ziplock bags. The nutritional and bioactive characterisation was carried out using official methods. NIRS discriminated the various clones of roasted and unroasted CBS. Carbohydrate was the predominant macronutrient, and ash content ranged from 5.25 to 8.24%. The CBS was high in potassium (2382–3144 mg/100 g) and low in sodium (25.67–51.33 mg/100 g). Total flavonoids and phenolics ranged from 8.61 to 40.71 mgQE/g and 6.34–12.25 mgGAE/g, respectively, for the roasted and unroasted CBS. To ensure better differentiation of cocoa beans from different clones using NIRS, incorporating roasting as a processing parameter is recommended.
