What is Lactase and How Does It Work in Milk?
Lactose is a sugar found in milk and other dairy products. The small intestine normally produces an enzyme called lactase to break down lactose into simpler, more easily digestible sugars called glucose and galactose. For people with lactose intolerance, the body doesn't produce enough lactase, so undigested lactose travels to the large intestine, causing symptoms like bloating, gas, and abdominal pain.
When you add lactase enzyme drops to milk, you are essentially performing the digestion process externally. The liquid lactase breaks down the complex lactose sugar into its simpler components before you even consume it. This 'pre-digestion' means that by the time you drink the treated milk, the enzyme has already done the work your body couldn't, allowing you to enjoy dairy without the unpleasant side effects.
Where to Buy Lactase Enzyme Drops
Lactase enzyme drops are widely available for purchase, making it simple to create your own lactose-free dairy. You can find them at most pharmacies, health food stores, and major online retailers. Some popular brands include Lacteeze and Milkaid. When buying online, you may also find generic or store-brand options. Always check the product's dosage instructions, as concentrations can vary between brands.
Lactase Drops vs. Lactase Pills
Many people are familiar with lactase supplements in pill or capsule form, often taken just before eating dairy. Here is a comparison to help you decide which is right for you:
| Feature | Lactase Drops | Lactase Pills/Capsules |
|---|---|---|
| Usage Method | Added directly to liquid dairy (milk, cream) to pre-treat it before consumption. | Taken orally just before or with a dairy-containing meal. |
| Best For | Preparing large batches of lactose-free milk for daily use, cooking, or for infants. | On-the-go consumption of various dairy products like cheese, ice cream, or restaurant food. |
| Speed of Action | Requires waiting, typically 24 hours in the refrigerator, for the enzyme to fully break down lactose. | Works quickly in the digestive tract upon consumption, with immediate or fast-acting options available. |
| Versatility | Limited to treating liquid dairy products. Not suitable for acidic dairy like yogurt or buttermilk. | More versatile for solid dairy products or meals containing hidden lactose. |
| Effectiveness | Allows for customizable lactose reduction, from partial to nearly complete, depending on dosage and time. | Effectiveness can vary depending on individual digestion and the type/amount of dairy consumed. |
Step-by-Step Guide to Making Your Own Lactose-Free Milk
Creating your own lactose-free milk at home is a simple and cost-effective process. Here’s a quick guide:
- Gather Supplies: You will need a container of fresh dairy milk (cow's milk works best), your lactase enzyme drops, and a measuring tool if needed.
- Determine Dosage: Follow the specific instructions on the lactase drops bottle. A common starting point is around 5-7 drops per liter (about 1 quart) of milk, but some brands may differ.
- Add and Mix: Add the recommended number of drops directly to the milk container. If the container is nearly full, pour a small amount out first to make room. Shake or stir thoroughly to ensure the enzyme is evenly distributed.
- Refrigerate and Wait: Place the milk back in the refrigerator and let it sit for at least 24 hours. This incubation period allows the enzyme sufficient time to break down the lactose. For a greater reduction in lactose, some instructions may advise waiting longer or using a higher dosage.
- Enjoy: After the waiting period, your milk is ready to use just like regular milk. The treated milk may taste slightly sweeter due to the breakdown of lactose into simpler sugars.
Important Considerations for Adding Lactase
While adding lactase drops is an excellent solution for many, it's important to keep a few things in mind:
- Flavor Change: As the lactase breaks down lactose into glucose and galactose, the milk will taste noticeably sweeter. This is a natural result of the process and doesn't affect the milk's safety.
- Acidity Matters: Lactase enzyme drops are not suitable for all dairy products. They are most effective in neutral pH liquids like milk but lose their effectiveness in acidic products like yogurt, buttermilk, or sour cream. For these items, lactase pills or naturally fermented varieties with active cultures are better options.
- Not for Milk Protein Allergy: This process addresses lactose intolerance, which is a digestive issue. It will not mitigate symptoms related to a milk protein allergy, which is an immune system response.
- Consult a Professional: Always consult a healthcare provider or a registered dietitian before starting any new supplement regimen, especially for infants or pregnant and breastfeeding women.
Conclusion
Yes, you can easily buy lactase enzyme drops to add to milk and other liquid dairy products to create your own homemade lactose-free versions. This provides a convenient and cost-effective alternative to pre-packaged lactose-free options, offering individuals with lactose intolerance a way to enjoy dairy without the associated digestive discomfort. By following a few simple steps, you can pre-treat milk, customize the level of lactose reduction, and continue to enjoy the nutritional benefits of dairy in your daily life.
