We all know that drinking milk is good for us. It is a source of calcium, protein, vitamins and minerals. However, it is essential to store fresh milk in the right way so that it does not lose its nutrients. Stored properly in opaque containers, these nutrients remain intact for longer periods of time
Vitamin A is a fat-soluble vitamin, while riboflavin is a water-soluble vitamin. Both of these vitamins are important for healthy skin, hair and nails. Vitamin A also plays an essential role in the maintenance of vision, especially night vision. Vitamin C is another beneficial nutrient found in milk that protects against free radicals and supports a healthy immune system.
Vitamin C (ascorbic acid) and most other vitamins can be sensitive to light or heat exposure which causes them to degrade rapidly over time. This can result in reduced nutritional value and even make them unsafe for consumption if stored improperly for long periods of time at room temperature
Vitamin A is essential for the growth and maintenance of cells. It helps to maintain the health of the eyes, skin and immune system.
Vitamin A is a fat-soluble vitamin that’s stored in your liver and other organs. Your body can't store it as well as water-soluble vitamins like C or B vitamins, but you do need some vitamin A every day to keep healthy because your body doesn't make enough on its own.
You need vitamin A to keep your eyes and skin healthy. Your eye color depends on how much beta-carotene (a type of carotenoid that comes from plants) you eat—the more beta-carotene you eat, the darker your iris will be—so it's no surprise that people who don't have enough vitamin A have trouble with night vision!
Opaque packaging or dark bottles made of glass or hard plastic will keep out the light and preserve nutrients in milk.
The sun's ultraviolet rays will destroy vitamin A, so milk should not be left in clear glass bottles for long periods of time. It has been estimated that a pint of milk exposed to sunlight for eight hours lost about half its vitamin A content.
Exposure to light also causes the loss of nutrients like vitamins C and B12 in some types of milk like skimmed milk.
Vitamin C is destroyed when exposed to light and this can happen even in a sealed bottle if it hasn't been stored in a dark place. Vitamin B12 does not seem to be affected by exposure but it may be less effective at preventing or curing illness if you drink it after light has damaged it. Skimmed milk is more sensitive because it contains less fat than whole milks so there's less protection from being exposed to light.
Besides, unlike plain white glass bottles, tinted glass bottles are opaque and their color provides protection from ultraviolet rays resulting in longer shelf life for the packaged product. Tinted glass bottles are also more appealing to consumers than clear glasses due to their appealing aesthetics. However, they are more expensive to produce than plain whites or clear glasses so they tend to be used by high-end retailers only.
The quality of milk is affected by storing it in clear glass bottles. Exposure to sunlight, fluorescent lights and any other artificial light sources can break down some vitamins like vitamin A and B12, causing them to become less effective.
Vitamin A is important for healthy eyesight, skin and hair growth. Vitamin C helps the body heal wounds, keep the immune system strong against germs and illnesses as well as helps with blood clotting. Vitamin B12 helps maintain brain function and red blood cell formation; riboflavin supports energy production and macronutrient metabolism while niacin supports many chemical reactions in our bodies including digestion, synthesis of proteins from amino acids, release of energy from carbohydrates as well as functions related to mental health such as mood stability
So, it's best to use opaque packaging or dark bottles made of glass or hard plastic which will keep out the light and preserve nutrients in milk.
