True/False Questions (2 pts each, for extra credit, for statements that you decide are false, explain why it is false or change statement to make it a true statement)
28. T/F Most retail bacon is fully cooked, ready to eat out of
the package.
29. T/F All
muscle components had a function in the live animal.
31. T/F Antioxidants are most effective in preventing oxidation, when added after off-flavors are noticed in meats.
32. T/F Collagen consists of high quality, good binding protein.
33. T/F If meat is
chopped or emulsified too long, there could be a breakdown of the batter,
because chopping too long results in
broken fat cells & free fat escaping the fat cell walls.
Short Answer Questions (2 points, unless otherwise indicated):
34.
Define
water-holding capacity, as it relates to meat (3 pts).
35.
Give
three reasons why water or ice is added to meat products(3 pts).:
36. Give two potential problems associated with adding alkaline phosphates to meat products.
37. What is the best alkaline phosphate to use in meat processing, and why?
38. Give three things that you would do to maximize particle definition of ground meats (3 pts).
39. A stable batter, or emulsion, is highly dependent upon:
40. What is theoretically wrong with using spice mixes, which contain all of the salt that is needed to make a sausage product.
41. Why should nitrite and erythorbate be added early in the mixing or chopping process?
42. Identify two things needed to extract proteins from meat systems.
