    Edible insect powder for enrichment of bakery products– A review of nutritional, physical characteristics and acceptability of bakery products to consumers
    (Elsevier BV, 2023-12) Amoah I; Cobbinah JC; Yeboah JA; Essiam FA; Lim JJ; Tandoh MA; Rush E
    Bakery products including bread are traditionally good sources of carbohydrate but not nutrient-dense. Enrichment with edible insect powder could improve the quantity and quality of protein, fat and dietary fibers to bakery products. A systematic search carried out on the databases PubMed, Scopus and ScienceDirect identified 44 articles that would answer the question: what is known about the effect of enrichment of bakery products with various edible insect powders on the physical, nutritional composition and sensory properties of bakery products. The search strategy and terms applied were (Insect* OR Edible insect* OR Entomophagy*) AND (Bakery product* OR Bake* product*). Bread was the most common bakery product that was insect-enriched, yet muffins/biscuits/crackers/cookies were also reported. Commonly reported edible insects and their larvae were crickets, mealworms, palm weevil larvae, grasshoppers and African emperor moth caterpillars. Before milling into powders, insects and larvae were pre-treated by freeze-drying, oven/tray and microwave drying, blanching and roasting but was not reported for all studies. Generally, bread with up to 10% and muffins/biscuits/crackers/cookies with 5% of insect powder were acceptable to consumers. New areas of research should focus on comparing the water activity, shelf-life and cost of pre-treatment processing methods alongside the nutritional properties of edible insect powders.

    Effect of cocoa consumption on postprandial blood pressure in older adults with untreated hypertension: A randomized crossover clinical trial
    (Nanchang University, Northwest University, Jiangsu University, Zhejiang University, Fujian Agriculture and Forestry University and John Wiley and Sons Australia, Ltd, 2024-07-15) Osei EO; Amoah I; Lim JJ; Tawiah P; Aduama-Larbi MS; Oduro IN; Cobbinah JC; Dare AP; Diako C
    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.

    The impact of ethnicity and intra-pancreatic fat on the postprandial metabolome response to whey protein in overweight Asian Chinese and European Caucasian women with prediabetes
    (Frontiers Media S.A., 2022-10-14) Joblin-Mills A; Wu Z; Fraser K; Jones B; Yip W; Lim JJ; Lu L; Sequeira I; Poppitt S; Li X
    The “Thin on the Outside Fat on the Inside” TOFI_Asia study found Asian Chinese to be more susceptible to Type 2 Diabetes (T2D) compared to European Caucasians matched for gender and body mass index (BMI). This was influenced by degree of visceral adipose deposition and ectopic fat accumulation in key organs, including liver and pancreas, leading to altered fasting plasma glucose, insulin resistance, and differences in plasma lipid and metabolite profiles. It remains unclear how intra-pancreatic fat deposition (IPFD) impacts TOFI phenotype-related T2D risk factors associated with Asian Chinese. Cow’s milk whey protein isolate (WPI) is an insulin secretagogue which can suppress hyperglycemia in prediabetes. In this dietary intervention, we used untargeted metabolomics to characterize the postprandial WPI response in 24 overweight women with prediabetes. Participants were classified by ethnicity (Asian Chinese, n=12; European Caucasian, n=12) and IPFD (low IPFD < 4.66%, n=10; high IPFD ≥ 4.66%, n=10). Using a cross-over design participants were randomized to consume three WPI beverages on separate occasions; 0 g (water control), 12.5 g (low protein, LP) and 50 g (high protein, HP), consumed when fasted. An exclusion pipeline for isolating metabolites with temporal (T0-240mins) WPI responses was implemented, and a support vector machine-recursive feature elimination (SVM-RFE) algorithm was used to model relevant metabolites by ethnicity and IPFD classes. Metabolic network analysis identified glycine as a central hub in both ethnicity and IPFD WPI response networks. A depletion of glycine relative to WPI concentration was detected in Chinese and high IPFD participants independent of BMI. Urea cycle metabolites were highly represented among the ethnicity WPI metabolome model, implicating a dysregulation in ammonia and nitrogen metabolism among Chinese participants. Uric acid and purine synthesis pathways were enriched within the high IPFD cohort’s WPI metabolome response, implicating adipogenesis and insulin resistance pathways. In conclusion, the discrimination of ethnicity from WPI metabolome profiles was a stronger prediction model than IPFD in overweight women with prediabetes. Each models’ discriminatory metabolites enriched different metabolic pathways that help to further characterize prediabetes in Asian Chinese women and women with increased IPFD, independently.
