The permissible limit of yeast and molds (cfu) as process hygiene criteria for satisfactory quality of Khoa/ Khoa based sweets as per FSSAI specifications is ________.
5 samples of pasteurized milk from a single lot were analyzed and their total plate counts were (cfu/ml): 25,000; 37,000; 15,000; 45,000 and 20,000.

The suggested standard for yeast and moulds count of satisfactory air quality in cheese processing rooms should be less than ---/\(\text{m}^{3}\)
Pectin is a polysaccharide which is a polymer of ________________.
Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Specific gravity of whole milk increases when held at lower/cold temperature. This phenomenon is known as Recknagel phenomenon.
Reason (R) : Reckangel phenomenon occurs mainly due to loss of entrapped gas when milk is held at lower temperature.
In light of the above statements, choose the correct answer from the options given below.
‘Musty potato' aroma in milk is caused by __________.
Given below are two statements:
Statement (I): Moseley count gives a better index of shelf life than aerobic mesophilic count as it determines the growth rate of bacteria when stored at low temperature.
Statement (II): Flavor rating at $7^\circ\text{C}$ is a useful shelf test as most of the enzymes responsible for off flavors are optimally produced and more active at this temperature.}
In light of the above statements, choose the most appropriate answer from the options given below.
