Name one factor that influences the shelf life of milk.

Storage temperature is indeed a critical factor that influences the shelf life of milk. Milk is a perishable product, and its quality can deteriorate rapidly if not kept at the appropriate temperature. When milk is stored at cooler temperatures, the growth of spoilage microorganisms is significantly slowed down, helping to maintain its freshness and extend its shelf life. Conversely, if milk is stored at higher temperatures, the rate of microbial growth increases, leading to quicker spoilage.

While aspects such as processing methods, packaging color, and even brand can influence the milk's quality and durability to some extent, none are as directly impactful on the immediate shelf life as storage temperature. Ensuring that milk is kept consistently refrigerated is fundamental for its preservation and safety.
