Nutrients & Nutritional Requirements

Classification, functions, chemical composition, food sources, and digestion of carbohydrates (monosaccharides, disaccharides, polysaccharides), proteins (amino acids, HBV vs. LBV proteins, complementary proteins), and fats (saturated vs. unsaturated fatty acids, cholesterol); functions, food sources, stability, and deficiency disorders of fat-soluble vitamins (A, D, E, K) and water-soluble vitamins (thiamine, riboflavin, niacin, folate, cobalamin, vitamin C); essential minerals (calcium, phosphorus, iron, iodine, sodium, potassium); dietary fibre (roughage) and water; deficiency diseases including kwashiorkor, marasmus, scurvy, rickets, osteomalacia, beriberi, pellagra, iron-deficiency anaemia, and endemic goitre; quantitative energy metabolism calculations using Atwater factors (4 kcal/g for carbs and protein, 9 kcal/g for fat) and Body Mass Index (BMI) assessments.

Food Commodities & Science of Cooking

Nutritive composition, culinary selection, preparation, and storage of core food commodities: cereals (rice, maize, wheat, sorghum, millet, starch gelatinization, dextrinization, gluten formation), roots and tubers (cassava, yams, cocoyams/macabo/taro, sweet potatoes, plantains, detoxification of cyanogenic glycosides in cassava), pulses and legumes (cowpeas/koki, groundnuts, soybeans, bambara groundnuts, antinutritional factors), meat, poultry, and fish (muscle structure, connective tissue collagen/elastin, tenderization methods, cooking changes), eggs (structure, freshness tests, coagulation temperatures, culinary functions like emulsification, binding, foaming, and thickening), milk and dairy products (casein, whey, pasteurization, sterilization, cheese, yoghurt), and fruits/vegetables (classification, pigments, vitamin retention, prevention of enzymatic browning); principles of heat transfer (conduction, convection, radiation) and cooking methods (boiling, poaching, steaming, pressure cooking, stewing, braising, baking, roasting, grilling, shallow and deep frying).

Meal Planning, Dietetics & Special Diets

Principles of balanced meal planning (nutritional adequacy, age, physical activity level, climate, economic constraints, sensory appeal, seasonal availability); nutritional requirements across lifecycle stages: infant nutrition (exclusive breastfeeding, colostrum, weaning/complementary feeding), toddlers and preschoolers, school children, adolescents (growth spurt, iron and calcium demands), adult manual workers versus sedentary workers, and elderly persons (reduced BMR, nutrient density, digestive ease); special physiological states: pregnancy (iron, folate, calcium, protein) and lactation (increased energy and fluid demands); therapeutic and modified diets: convalescents, vegetarians (vegan, lacto-vegetarian, lacto-ovo vegetarian), and diet-related non-communicable conditions (type 2 diabetes, hypertension, cardiovascular disease, obesity); budget meal planning utilizing low-cost indigenous Cameroonian foodstuffs (soya beans, cowpeas, green leafy vegetables like ndoleh, waterleaf, cassava leaves, crayfish).

Food Spoilage, Hygiene & Preservation

Biological and chemical causes of food spoilage: microorganisms (bacteria, moulds, yeasts) and autolytic enzymes; environmental conditions governing microbial proliferation (FATTOM: food, acidity/pH, time, temperature danger zone 5°C–63°C, oxygen, moisture/water activity); common food poisoning pathogens (Salmonella, Staphylococcus aureus, Clostridium botulinum, Bacillus cereus, Escherichia coli) and aflatoxins in groundnuts/maize; personal hygiene protocols for food handlers, kitchen sanitation, safe storage temperatures (chilling at 1°C–4°C, freezing at -18°C), and prevention of cross-contamination; traditional and modern preservation principles: dehydration/sun-drying, hot and cold smoking, salting (osmotic plasmolysis), sugar preservation (jams, jellies, marmalades at 65%–68% soluble solids), refrigeration, freezing, heat processing/canning, pickling/vinegar preservation, and chemical preservatives.

Kitchen Planning, Equipment & Consumer Education

Kitchen planning and ergonomics: the work triangle concept (sink/washing center, cooker/cooking center, refrigerator/preparation and storage center), common kitchen layouts (U-shaped, L-shaped, galley/corridor, single wall); kitchen safety protocols and emergency first aid for burns, scalds, cuts, falls, and kitchen grease fires (smothering methods, fire blankets, avoiding water on oil fires); selection, proper usage, cleaning, and maintenance of kitchen equipment and cookware materials (stainless steel, cast iron, aluminium, non-stick Teflon, enamel, traditional earthenware pots); table appointments, cover layout, and meal service styles (buffet, family/English, plated/American); consumer education, prudent food shopping practices, unit pricing, bulk buying, and critical analysis of food packaging labels in Cameroon (expiry dates, best before dates, ingredient lists, nutritional panels, ANOR certification).
