Which milk is better in terms of nutrition, bottled milk, bagged milk, or boxed milk?

  Dairy products are an important source of calcium supplementation, and milk is known as the "white blood" of the human body. It is rich in minerals, calcium, phosphorus, iron, copper, manganese, and potassium, making it the best source of calcium for the human body, and the calcium phosphorus ratio is very appropriate. So, which milk is better for nutrition, boxed milk or bagged milk? How should we choose?

1. Bottled milk

  The initial packaging of milk was in glass bottles, which not only prevented air pollution but also hindered the diffusion of flavor compounds. However, glass bottles are prone to damage during transportation and have high costs. With the development and maturity of aseptic cold filling technology, as well as the widespread application of cold chain transportation and storage, PET bottles are increasingly replacing glass bottles and HDPE bottles in milk packaging due to their transparency, good glossiness, high-quality appearance, non-toxic and odorless characteristics.

2. Bagged milk

  Plastic bag packaging is economical and can block air and light through special treatment. However, compared to bottled and boxed packaging, plastic bag packaging materials are thinner and the barrier properties are not as good. Bagged milk will accelerate the rise of milk fat under light conditions, resulting in layering and affecting its appearance. In addition, under the excitation of light, active oxygen substances such as riboflavin and porphyrin in milk are produced. They react with proteins, vitamins, and fats to produce aldehydes, ketones, methionine, and dimethyl disulfide, which can damage the nutrition and flavor of milk. Bagged milk has a shorter shelf life and a relatively lower price. For example, the familiar pasteurized milk usually has a shelf life of 1-3 days, and some can last up to a week. This type of milk is suitable for immediate consumption and usually needs to be stored in a refrigerator. It is precisely because bagged milk has a shorter shelf life that its taste is fresher.

3.    Boxed milk

  Boxed milk can effectively block air and light. Boxed milk generally has a relatively long shelf life and can be stored without preservatives, even at room temperature for six months.
