This set of Dairy Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Regulations – 1”.
1. Two states dominate the total U.S. cheese production. These two states are?
a) Texas and California
b) Texas and Florida
c) New York and Wisconsin
d) Wisconsin and California
Explanation: Wisconsin and California have the highest cheese production among all USA states. Cheese a very popular dairy product.
2. Some soft serve frozen dairy products have replaced milk fat with?
a) Peanut butter
d) Vegetable oil
Explanation: Frozen desserts have vegetable oil in it. These frozen yogurts are also a replacement to traditional ice cream. They replace milk fat with vegetable oil.
3. By FDA definition of an imitation product, which of the following is NOT true?
a) Taste like the real product it represents
b) Has the same nutritional value as the real product it represents
c) Looks like the real product it represents
d) Imitation products aren’t regulated by the FDA
Explanation: A food that is a substitute for and resembles another food shall not be deemed to be an imitation provided it meets each of the following requirements: (i) It is not nutritionally inferior to the food for which it substitutes and which it resembles.
4. A substitute product by FDA definition meets all of the following statements except?
a) Taste like the real product it represents
b) Has the same nutritional value as the real product in replaces
c) They looks like the real product it represents
d) Imitation products are not regulated by the FDA
Explanation: Imitation products are regulated by FDA. Hence the statement is not true.
5. Some dairy food products have a “REAL” seal on the package. This seal cannot be placed on a package that does NOT adhere to the following standards.
a) Produced from U.S. milk
b) Meets federal and state standards
c) Imitation or substitute foods
d) Produced from NON-organic sources
Explanation: Products bearing the REAL® Seal are certified as having been made in this country with milk from cows on U.S. dairy farms and without imported, imitation, or substitute ingredients. The REAL® Seal means not only that a product is made with real dairy foods, but that it is made in the USA.
6. Osteoporosis may be reduced by consuming adequate quantities of milk and/or milk products. Osteoporosis is the?
a) Inflammation of the skin cells causing hair loss and scaling of the skin
b) Condition of deterioration of the soft tissue in the retina, leading to blurry vision and poor eye sight
c) Loss of bone mass due to a decrease in the bone matrix and minerals
d) Development of a hard calloused layer of skin upon the sole of the foot
Explanation: Osteoporosis is a bone disease that occurs when the body loses too much bone, makes too little bone, or both. It may be reduced by the consumption of milk and milk products.
7. Properly processed UHT milk may be stored at room temperature for?
a) 24-28 hours
b) 10-15 days
c) Several weeks
d) 6 months
Explanation: An alternative process is HTST pasteurization (high temperature/short time), in which the milk is heated to72 °C (162 °F) for at least 15 seconds. UHT milk packaged in a sterile container, if not opened, has a typical unrefrigerated shelf life of six to nine months.
8. Milk sold through commercial outlets is certified to be from herds free of?
b) Displaced Abomasums
c) Broken Udder Suspensory Ligaments
Explanation: Commercial outlet makes sure that the milk sold by them are from the herds free of tuberculosis. Hence consumer health is not suffered.
9. Humans may contract ______________ from using raw cows’ or goats’ milk, should the animals have brucellosis.
a) Undulant fever
c) Whooping cough
d) Night blindness
Explanation: Undulant fever: An infectious disease due to the bacteria Brucella that characteristically causes rising and falling fevers, sweats, malaise, weakness, anorexia, headache, myalgia (muscle pain) and back pain. In the US, infection occurs more frequently by ingesting contaminated milk and dairy products.
10. Milk is produced from female’s mammary glands. These mammary glands are examples of ________
a) Adrenal gland
b) Excretory gland
c) Absorbatory gland
d) Exocrine gland
Explanation: A mammary gland is an exocrine gland in mammals that produce milk to feed young offspring. Mammal’s lactation, the production of enough milk for nursing, occurs only in phenotypic females who have gestated in recent months or years.
11. The secretary tissue within the mammary gland is a grapelike structure called?
c) Glanus cistern
d) Annular ring
Explanation: A mammary alveolus is a small cavity or sac found in the mammary gland. Mammary alveoli are the site of milk production and storage in the mammary gland.
12. The California Mastitis Test (CMT) asks that you used only ___________ milk.
b) Milk after dry-off
c) The first stream during milking
d) The 2nd stream during milking
Explanation: The California mastitis test (CMT) is a simple cow-side indicator of the somatic cell count of milk. It operates by disrupting the cell membrane of any cells present in the milk sample, allowing the DNA in those cells to react with the test reagent, forming a gel. It uses 2nd stream during milking.
13. How many cc’s of milk is required for the CMT?
a) 6 cc
b) 4 cc
c) 2 cc
d) 1⁄2 cc
Explanation: The California mastitis test (CMT) is a simple cow-side indicator of the somatic cell count of milk. It requires about 2cc of milk.
14. The CMT should be read within _____________
a) 10 sec
b) 20 sec
c) 30 sec
d) 40 sec
Explanation: The CMT test should be analyzed within 20 sec. Otherwise the test value change.
15. What is the healthiest range for somatic cell counts?
Explanation: A somatic cell count (SCC) is a cell count of somatic cells in a fluid specimen, usually milk. General agreement rests on a reference range less than 200,000 cells/mL for uninfected cows.
