1 National Exams May Agric-Ali, Physical Properties of Biological Materials 3 hours duration NOTES: 1. If doubt cxi.st.s as to the interpretation of any question, the candidate is urged to submit with the answer paper, a clear statement of any assumptions made. 2. This is a CI,OSED BOOK EXAM. Approved calculator is permitted. One aid sheet allowed written on both sides. 3. FIVE (5) questions constitute a complete exam paper. The first five questions as they appear in the answer book will be marked. 4. Marks for each question are given. 5. Some questions require an answer in essay format. Clarity and organization of the answer are important. Be brief, too the point and concise. Marking Scheme five questions out of nine (all questions cany 20 marks) l. 20 marks total 2.

2 Do any 5 questions l. T he specific heat of a 12% moisture yellow-dent corn was determined using a thermos hottle as a calorimeter. The mass of the thermos was 54.5 g and the mass of the grain sample waq 90 g. The thermos and corn were first heated to 73 C and then 255 g of water at 21 C was poured into the thermos. When the system was sealed and at equilibrium its tempcratuce was 30 C. If the speci fie heat of the thermos was kj/(kg K.) and of water was kj/(kg K), determine the specific heat of the corn using the method of mixtures. (20 marks) 2. Using bench scale laboratory tests, or batch equipment tests, how would you determine or estimate the following: (a) The thermal conductivity and diffusivity of a food product. (10 marks) (b) The maximum tolerable freezing rate in terms of some frozen. product quality attributes. (10 marks) 3. A rotational narrow gap viscometer, with a spring constant equivalent to 7187 dynes/cm foll scale reading on the indicator, is used on a viscometer with 1 cm outside diameter (OD) for the inner cylinder and 1.5 cm inside diameter (ID) for the outer cylinder. The cylinders are 6 cn.1 high. Assume that end effects are negligible. The following readings, as a percentage of full scale on the indicator, were obtained at various spindle speeds for a food product. Determine the flow behaviour index (n) and consislency coefficient (b) of the fod. Speed (N), rpm Torque indicated (% full scale) IO Use log-log graph paper or ordinary graph provided. (20 marks) 4. (a) Sketch the recovery of fluid viscosity vs. time dtrri.ng agitation at a very low shear rate fo llowing rapid agitation. Distinguish between flui ds that recover consistency and those that do not.

(6 marks) (c) The proportionality constants between stress and strain are called moduli (M), i.e. M = stress/strain. Define in words and then in symbols, the following moduli: modulus of rigidity, modulus of elasticity, bulk modulus and modulus of compressibility. (8 marks) 5. (a) Sketch a typical General Food Textural Profile curve for a food product which also shows adhesiveness. Label the curve with the primary textural parameters and areas under the curve. Define in formula form cohesiveness, gumminess and chewiness. (l 0 marks) 04-Agric-Afi May 2016 Page 2 of fi
