Fresh milk can be heated, especially during winter or for the purpose of sterilization, and heating is a common practice. However, the following points should be noted: 1. Temperature control: Avoid boiling fresh milk, as high temperatures can destroy nutrients such as proteins and vitamins. Generally, heat the milk only until it is slightly warm or lukewarm. 2. Heating method: Use a water bath method—place the milk container in hot water and heat gradually to prevent excessive temperature from direct heating. Alternatively, use a microwave, but heat in short, intermittent intervals, and stir thoroughly afterward to prevent localized overheating. 3. Prevent scorching: Monitor closely during heating to avoid burning the milk, as burnt milk may produce harmful substances. 4. Storage conditions: If the fresh milk has been opened, check its freshness before heating to ensure it hasn't spoiled. Unopened fresh milk can be stored directly in the refrigerator; once opened, it should be consumed promptly or refrigerated and used within 48 hours. 5. Health considerations: Some individuals may have difficulty tolerating cold milk, which can be improved by warming it. However, heating does not break down lactose, so people with lactose intolerance should choose lactose-free or lactase-treated dairy products.
