Yoghurt was produced and flavoured with graded levels of watermelon pulp and juice. Watermelon (Citrullus lanatus) juice and pulp was used to substitute 0, 10, 20, 30, 40 and 50% of yoghurt. The chemical, sensory and microbiological properties of the yoghurts were determined. The results showed that the pH of the yoghurt ranged from 4.68... Continue Reading

Rice production in Ghana is faced with the major challenge of low patronage. This is due to its poor physical and sensory quality rendering it ‘low grade’ rice. Among the many local varieties of rice in Ghana, Viwonor is perceived to be a low grade rice whereas Jasmine 85 a high grade. Large quantities of rice are imported to address... Continue Reading

Lactic Acid Bacteria (LAB) are the most widespread of organisms responsible for food fermentation and have been applied as commercial starter cultures in many food industries.
