Abstract: Bobolo is a thick fermented, popular traditional food, derived from cassava (Manihot esculenta Crantz) in Cameroon. The physical, sensory, chemical and microbiological characteristics of Bobolo were analyzed, in order to identify the suitable cassava varieties and the local fermentation method with the best nutritional and industrial properties. The range of L* (lightness / darkness), a* (redness / greenness), b* (yellowness / blueness) were 75.00±0.65-80.07±0.60, 3.7±0.57-4.90±0.60, 11.9±08-17.2±0.75 respectively. Sensorial characteristics (color, pasting, and global quality) evaluation reveal that Bobolo made with aerobic fermentation with ferment had the best characteristics and independent of varieties. The campo varieties presented superior characteristics compared to the other varieties. Bobolo of different varieties and the same processed cassava products had an average range of moisture content (40.85±0.91 – 44.36±0.33%), carbohydrates (38.72±0.66 – 40.91±1.12%), protein (1.18±0.04 – 1.44±0.01%), total fat (4.02±0.05 – 4.38±0.14%), crude fiber (1.71±0.05 – 2.77±0.15%), ash (0.28±0.05 – 0.36±0.02%) and cyanure (4.28±0.22 – 6.49±0.12mg/kg) and where they varied significantly between products and variety. The mineral analysis result in the Bobolo samples ranged 0.04±0.00 - 0.07±0.00 mg/100 g Ca, 0.07±0.00 – 0.10±0.00 mg/100 g Mg, 0.74±0.05 – 0.88±0.04 mg/100 g K, 7.82±0.87 – 11.96±1.00 mg/100 g Na, 5.7±0.14 – 8.7±0.14 ug/g Zn and 15.37±0.18- 21.15±0.77 ug/g Mn respectively. The Bobolo produced contained more mesophilic total flora and molds and yeasts and was absent from Eschericha coli, Staphylococcus aureus, Clostridium spp. Bacillus cereus and Salmonella spp. Therefore, the types and varieties of cassava fermentations influence the quality of Bobolo.

Abstract: Background: Glycemic index (GI) is a numerical system that ranks carbohydrate-containing foods by how much they raise blood glucose level. Understanding GI is beneficial in diet management, especially for weight loss or diabetic people. Various types of food, such as functional foods, have recently gained attention for their health benefits, with sourdough bread being a notable example. As sourdough bread becomes a preferred option for weight and diabetes management, disclosing its glycemic index is crucial. Objective: This study aims to assess the glycemic index of a newly available bread, the flaxseed oats sourdough bread. Methodology: Ten healthy subjects aged between 23 to 37 years old were recruited (mean 28.7 ± 4.4 years) and required to fast and then consume 50 g of available carbohydrate portions of test and reference foods. Finger capillary blood samples were collected at the start (fasting, 0 minute) and 15, 30, 45, 60, 90 and 120 minutes after consumption. The GI was calculated from the ratio of incremental area under the curve (iAUC) to reference food. Result: The results show that flaxseed oats sourdough bread has a GI of 37.3 which is classified as low GI. Conclusion: Determining the GI value of this bread provides valuable data that can enhance dietary recommendations for weight and diabetes management. Implementing a low GI diet nationwide necessitates ongoing research, public education, and collaboration with food manufacturers to ensure consumers have access to healthier carbohydrate options.
