Which material is known to absorb milk fat and requires cleaning in alkaline detergent?

Rubber is known to absorb milk fat, which can create challenges in maintaining milk quality and hygiene standards. The porous nature of rubber allows it to trap fats and proteins, leading to the potential buildup of residues that can compromise milk quality if not properly cleaned.

To effectively clean rubber components, alkaline detergents are often used. Alkaline detergents are effective at breaking down fats, oils, and proteins, making them essential in removing the residues absorbed by rubber. Regular cleaning with the appropriate detergents is necessary to ensure that the rubber does not harbor any bacteria or unwanted contaminants that could impact the quality of the milk.

In contrast, materials like plastic, glass, and stainless steel do not have the same tendency to absorb milk fat to the extent that rubber does. While they may require cleaning to remove surface residues, especially after prolonged use or exposure to milk, they are generally easier to clean and maintain without the risk of absorbing fats.
