Can boxed pure milk be heated

Boxed pure milk can be heated, but attention should be paid to temperature control and method selection. The heating temperature should not exceed 60 degrees Celsius to avoid damaging nutrients and protein denaturation. Common heating methods include water-resistant heating and short-term microwave heating.

Boxed pure milk adopts aseptic packaging technology, and the inner aluminum foil can withstand a certain high temperature, but boiling directly may cause the packaging to expand and break. Cross water heating is the safest way. Soak unopened milk boxes in hot water below 80 degrees Celsius for 5 minutes to both heat up and prevent nutrient loss. Microwave heating requires cutting open the packaging and pouring it into a heat-resistant container. Heat at low to medium power for 30 seconds before stirring to prevent local overheating. Heating at high temperatures for a long time can damage whey protein and vitamin B groups in milk, reduce calcium absorption, and may also produce sediment that affects taste.

Caution should be exercised when heating in special circumstances, such as lactose intolerant individuals, as heating may worsen bloating symptoms. Some boxed milk that has undergone ultra-high temperature sterilization is prone to flocculent substances due to changes in protein structure after heating. Although it does not affect safety, it is not recommended for consumption. Heating milk for diabetes patients may accelerate the absorption of sugar, so the temperature should be controlled at about 40 ℃. If the packaged milk is refrigerated for more than 24 hours after opening, it is necessary to confirm that there is no layering or spoilage before heating.

When drinking heated milk in daily life, it can be paired with whole wheat bread or nuts to help delay sugar absorption. When choosing a heating method, prioritize nutrient retention and avoid drinking hot milk on an empty stomach to reduce gastrointestinal irritation. The recommended daily intake of dairy products is 300-500 milliliters. In hot weather, it can be refrigerated and consumed directly. In cold seasons, it is more beneficial to heat it up to a temperature similar to body temperature for better health.
