6 - Question
Citric acid is used in small quantities that speeds the conversion of nitrite to nitrous acids, which in turn combines with myoglobin to form the stable red color of meat.
a) True
b) False
View Answer
Explanation: Citric acid is used in small quantities that speeds the conversion of nitrite to nitrous acids, which in turn combines with myoglobin to form the stable red color of meat.
7 - Question
Nitrosamines are found in cured meats due to the reaction of amines with nitrous acid (during curing) and these nitrosamines are carcinogenic in nature
a) Yes
b) No
c) No data available
d) Work under progress
View Answer
Explanation: According to the chemical reaction and chemistry involved, reaction of amines with nitrous acid should yield Nitrosamine. Also, it is proven that these are carcinogenic. But the manufacturers refuse to accept their presence in cured meats and that they are isolated during the curing process. Hence this concern is still under progress.

a) Take part in reduction of metmyoglobin to myoglobin and accelerate the rate of curing
b) Ascorbates react chemically with nitrite to increase the yield of nitric oxide from nitrous acid
c) Excess ascorbate acts as antioxidants and stabilizes color and flavor
d) All of the mentioned
View Answer
Explanation: All of the mentioned are roles of Ascorbic acid in curing.
10 - Question
Which of the following is NOT a function of phosphates in curing?
a) Retarding development of rancidity
b) Raising pH and causing unfolding of muscle proteins. Hence making more sites available for water binding
c) Improve retention of brine and improvement in yield
