Question

The reading of 1.026 in the lactometer shows
A) Adulterated milk
B) Unadulterated milk
C) Adulterated ghee
D) Unadulterated ghee

Answer 1

Hint: This reading in the lactometer shows when the milk is pure with no added substances. Lactometer shows the amount of water in the milk so the deeper the bulb sinks, the more impure the milk. A lactometer is used to calculate the volume and the basic gravity of milk in the milk that you are consuming.

Complete answer:
Adulteration is an unwanted and inferior mixing process in food. The food-added material or material is referred to as adulterants.
Water is the most common milk adulterant.
A lactometer can detect water adulteration in a milk. The density of the milk decreases when water is added to the milk and this is detected via a lactometer. The less than 1.026 reading of the lactometer shows milk adulterating by water.
Adulteration simply signifies mixed impurities and pure means unadulterated.

Thus, the correct answer is option B.

Note:
The instrument is composed of a TEST-TUBE and a METER BULB and is very simple to use. To verify the purity of cow's milk a lactometer is used. Milk is poured into and allowed to be able to stand until cream is formed, so milk content is determined by the depth of the cream deposit in degrees. If it's pure, the lactometer floats and the lactometer sinks when it is adulterated or impure. Mr. Dicas invented the lactometer. Lactometer invented by Mr. Dicas of Liverpool. Lactometer is a medium for monitoring the pureness of milk samples.
