Article Synopsis
  • - South Africa has a high-quality maize production but still faces significant food insecurity and malnutrition, with many people relying on maize-based dishes like pap, leading to a lack of diet diversity.
  • - The study explored creating consumer-friendly nixtamalised maize products, specifically chutney-flavored maize chips, which received moderate approval from consumer panels and favorable purchase intent.
  • - Nutritional analysis of the nixtamalised chips showed good levels of energy, fiber, and essential minerals, indicating that this method could be a viable solution to improve nutrition and combat food insecurity in South Africa.

Cactus pear mucilage is a novel, inexpensive hydrocolloid that is used to add nutrients, body and texture to functional food products. However, varied physicochemical and technological properties of powders when cultivar and harvest month of cladodes differ could lead to differentiation in the application of mucilage powders. To that end, three - (Algerian, Morado and Gymno-Carpo) cultivars and one (Robusta) cultivar were harvested over a 6 month period and evaluated in this study.
