Vitamin A stability during storage of fortified gari produced using different fortification strategies.

Food fortification is an effective strategy to combat vitamin A deficiency. Gari, a cassava-based West African food product, is an interesting product to fortify with vitamin A, but the low stability of vitamin A poses a challenge. We showed that toasted wheat bran can stabilise vitamin A as retinyl palmitate (RP) during storage of RP-fortified gari to a limited extent.

Assessment of chocolate retail in Ghana and willingness to use cooling devices.

Cold temperature (≤20 ᵒC) storage or handling is required to maintain the quality characteristics of chocolate after production throughout the supply chain. The objective of this study was to assess the retail conditions, challenges, and willingness of retailers to use cooling devices. A total of 228 chocolate retailers sampled from Kumasi and Accra were interviewed using questionnaires with both closed and open-ended questions.

Gender-Disaggregated Consumer Testing and Descriptive Sensory Analysis of Local and New Yam Varieties.

Gender-disaggregated sensory evaluation has become an essential element that could enhance breeding activities by increasing the adoption of new varieties. The effect of age, sex and geographical location on descriptor preferences for boiled and pounded yam were studied using descriptive and consumer testing. Attributes with definitions and measurement scales were used to generate lexicons for boiled and pounded yam.

The effect of gender on end-user preferences for yam quality descriptors.

Improving the effectiveness of breeding programs could be achieved by breeding for consumers' preferences. The relationship between gender and consumer preferences for yam was studied using purposeful sampling for key informants, focus group discussions (FGDs), and individual interviews. Data from qualitative interviews were transcribed and quantitative data analyzed using SPSS (version 20).

Effect of Cocoa Beverage and Dark Chocolate Consumption on Blood Pressure in Those with Normal and Elevated Blood Pressure: A Systematic Review and Meta-Analysis.

Cocoa is a major dietary source of polyphenols, including flavanols, which have been associated with reduced blood pressure (BP). While earlier systematic reviews and meta-analyses have shown significant effects of cocoa consumption on systolic BP, limitations include small sample sizes and study heterogeneity. Questions regarding food matrix and dose of polyphenols, flavanols, or epicatechins remain.
