Chapter 2, Problem IBDWPA

Explain the following functional properties indicating the macronutrients which exhibits such functionalities and how they can be applied in food product development. dextrinisation caramelisation preserving gelation denaturation coagulation shortening plasticity aeration retention of moisture gelatinisation

In the following cases, suggest the food composition which is being analyzed by the method. Would the food composition measured be 'overestimated' or 'underestimated'? Explain your answer briefly.  (a.) Lowry method: the presence of reducing sugars; (b.) Phenol-sulphuric acid method: the presence of starch; (c.) GOPOD method: analysis under a wrong pH environment; (d.) 2,6-Dichloroindophenol titration: the presence of matrix of reducing agents.

Define the terms essential and bioavailable Give an example of two essential macronutrients List 2 nutrients/chemicals that decrease the bioavailability of iron 2 nutrients/chemicals that decrease the bioavailability of calcium

Why is ME (Metabolized energy) the best energy value used to formulate poultry rations?

Enumerate at least three (3) importance of nutrients.   Differentiate macronutrients and micronutrients. Provide three (3) examples of each.   Provide a chemical test to detect the presence of the following: a.) carbohydrates b.) proteins c.) fats d.) calcium

Micronutrients derives from the Greek prefix macro which means which of the following?

Look at the nutrition labels for a Blueberry Nutrigrain Bar and a Blueberry RX Bar, also paying close attention to the ingredient lists provided in each. Answer the following questions: What is the difference between total sugars and added sugars? How do the total sugars and added sugars differ in these two bars? What are the biggest differences in the ingredient lists in these bars? Choose one ingredient that you have not heard of from the list from either bar. Explain to the class what the ingredient is and what its purpose is.

Discuss the differences between GE (Gross energy), ME (Metabolizable energy), and DE (Digestible Energy). Among the three values, which one is the most accurate estimate of energy value of a feedstuff and why?
