Why does lactose-free milk taste sweeter?

The lactose-free milk has added lactase to it. The enzyme that is responsible for the breakdown of the lactose, a disaccharide that is the part of milk. So when this added lactase reacts with the lactose, it breaks down the lactose into glucose and galactose. 

Glucose is much sweeter as compared to lactose therefore the lactose-free milk has a sweeter taste than regular milk. Thus, lactose-free milk and regular milk does have different flavor profiles.

Moreover when it comes to the texture or the consistency of the lactose-free milk then it has the same consistency as that of regular milk. It can be used as a perfect milk substitute in your coffee, tea, pastry, or any other recipe where regular milk is called for.

If you mostly use nonfat or skim milk then the consistency of the lactose-free milk will feel a bit creamier to you but otherwise, it has a comparable consistency to the whole milk.

Lactose free-milk is made from the milk that is collected from the cows. It has a lactase enzyme additionally added to it that breaks down the lactose part of the milk and makes it suitable for lactose-intolerant people. 

As lactose-free milk has whey and casein present in it, therefore it is not suitable for people having milk allergies. Dairy-free milk is recommended for people having milk allergies as it does not contain any milk protein, or milk products present in its formulation.

As lactose-free milk is collected from the cows therefore it is not suitable for those who are vegan. Therefore vegans can go for dairy-free milk (plant-based milk).

Is the texture of lactose-free milk the same as that of plant-based milk?

Lactose-free milk has a noticeably different texture than plant-based milk variants like soy milk or almond milk. The plant-based milk variants are thinner as compared to lactose-free milk. Therefore lactose-free milk serves the purpose greatly when it comes to baking and cooking confectionery items owing to its more creamy texture.

Is the nutritional value of lactose-free milk different from regular milk?

The nutritional profile and texture of lactose-free milk are approximately the same as that of regular milk. It is a great source of protein and approximately provides 8 g of protein per cup (240 ml). Lactose-free milk is also rich in many micronutrients like phosphorus, calcium, riboflavin, and vitamin B12.

Moreover, there are many varieties of lactose-free milk in the market that are additionally fortified with vitamin D which along with calcium helps in maintaining your bone health.

Lactose intolerance and lactose-free milk

Lactose is a disaccharide sugar that is present in milk while lactase is the enzyme that is responsible for breaking down lactose into simpler sugars like glucose and galactose which are then used by the body to produce energy that is required to carry out the daily activities of life.

In some people the lactase production is inadequate, therefore such people are not able to fully digest the milk. 

Most of the time the condition of lactose intolerance develops at the age of 2-12 and some people even regain their lactose digesting ability in adulthood while others have to live their whole life with it. Moreover, lactose intolerance is also a problem with elderly people as the level of lactase that is secreted in their body naturally decreases as they age. Approximately 70% of the adult population of the world has been suffering from lactose intolerance but these figures vary for different countries.

If lactose intolerant people consume milk or milk-related products then they can develop several gastrointestinal issues including gas, bloating, nausea, vomiting, belching, diarrhea, and severe abdominal pain.  

Therefore the people with lactose intolerance are directed to consume lactose-free milk in which the lactose is already broken down by the added lactase enzyme.

How to spot bad lactose-free milk?

You can tell if the lactose-free milk has gone bad or not by considering its appearance, smell, and texture.

If you see a mold or off-colors in the milk, it can be an indication of bad milk.  Moreover, lactose-free milk that has gone bad has a sour or acidic smell in it. The thick or clumpy texture is the indication that your lactose-free milk has started curdling and it is better to discard it. We do not recommend you to taste bad milk but if you still want to try, lactose-free milk that has gone bad will be a bit bitter.
