01) Goat milk contains a high nutrient profile compared to cow milk. Whey protein of goat milks extensively studied which, therefore, is being considered incorporating into fruit beverages.Whey-fruit flavored beverages are subjective to reduce the risks associated with cardiovascular diseases. A research group recently developed a whey-orange flavored juice using microfiltration technology. Imagine that you are one of the researchers of this study group and are asked to develop a sensory analysis test for this beverage. (a) Explain the term 'sensory evaluation' as it applies to food (5 marks). And make a list of the sensory attributes that you are planning to evaluate? (5 mark s). (b) Make a seven-point scale sensory table for each sensory attribute you selected (10 marks). (c) Briefly describe two main methods that can be used for conducting sensory evaluation of this beverage product (20 marks).

Question 3 Insulin is a protein which regulates the body's blood sugar levels by aiding the conversion of glucose to glycogen. Diabetes is a disease resulting from insufficient insulin production by the pancreas and so insulin must be obtained by other means. Recombinant DNA technology enables the production of insulin that is suitable for humans in other organisms such as yeasts. During this process, the human insulin gene is synthesised and introduced into the yeast cell by being attached to a plasmid where the insulin is made. a. Explain why the plasmid in the yeast is regarded as a vector. b. Explain why the following types of enzymes are used in the production of genetically engineered insulin. i. restriction endonucleases ii. ligases C. Briefly explain why it is possible to exchange DNA molecules between different species.
