For home brewing and winemaking, dissolve one teaspoon of sodium metabisulfite granules per two point two gallons of water to sanitize equipment or preserve beverages. For food preservation, dilute appropriately according to your specific recipe guidelines to prevent browning. Always handle with care using gloves and protective eyewear in a well-ventilated space, as it can cause skin and eye irritation.

It is what it says it is. Preservatives on Dropy are definitely more expensive than going to a local store if you can find one but this preservative in particular is so powerful that it will last virtually forever For most people. You absolutely need a scale accurate too 0.001g If you intend to use this for small batches of products.
works well for the application. Precipitates gold from a gold chloride solution
We are big campers and kayakers and dried fruit is expensive. I purchased a dehydrator recently and bought up bananas, apples and oranges, lemons and cranberries and noticed the instructions said to treat some fruit first.This was the product recommended to me and it was inexpensive and worked very well.
I use this to take chlorine out of my swimsuits. NEVER USE VINEGAR. Less than 1/2 teaspoon of Sodium Metabisulfite per gallon of water will remove all the chlorine in your suit. The suit retains its color and shape and simply lasts 8-10 times longer. Chlorine remains in the suit even after you're out of the pool and have dried off. The chlorine continues to damage the elastic and lycra of suits. That is why suits that were put away after the summer swim season, even though they were washed are faded and baggy when you get them out the following year. In my case swimming 5-6 times a week soaks the suit in chlorine and in just a few months my expensive suit is shot. Either it has lost its shape or the fabric has deteriorated to the point it starts to be see-through in areas.After each swim I rinse the suit in cold water in a sink and spin the water out. Then at home I throw a pinch of Sodium Metabisulfite in a small bucket of water and let the suit sit for at least 30 seconds, swish it around a few times, spin the water out, and hang it up to dry inside. Even polyester suits (they have elastic bands that are destroyed by chlorine) last a lot longer too. Keep the solution fairly small....enough to easily cover the suit by 2-3 inches. The SMBS and water solution will only last a couple of days and needs to be made new. Obviously if you're going to get the chlorine out of the suits for the whole family, get a bigger bucket.At 1 teaspoon of SMBS per 2.2 gallons of water we're talking pennies to preserve a swimsuit, some of which cost $100 and up. The Sodium Metabisulfite works better than many of the commercially produced suit saver products and it's much more economical.
Good product, & shipping
FAQs
What is sodium metabisulfite food grade used for?
Food grade sodium metabisulfite is primarily used as a food preservative and antioxidant. It effectively prevents fungal or bacterial growth and stops the browning of fruits and vegetables during dehydration. It is also widely used in beer and wine making to sanitize equipment and inhibit wild yeast growth.
Is sodium metabisulfite a bad preservative?
Sodium metabisulfite is a safe and highly effective food-grade preservative when used within established legal limits and proper mixing ratios. However, because it contains sulfites, it can trigger respiratory or allergic reactions in sensitive individuals, particularly those with asthma. It must always be handled with appropriate care.
How much sodium metabisulfite per Litre should be used?
The exact dosage depends heavily on the specific application, such as winemaking or equipment sterilization. As a general benchmark derived from standard guidelines, one teaspoon treats approximately eight point three liters of water for certain sanitizing processes. Always consult standard brewing or food preservation recipes for precise measurements.
Is the Duda Energy Sodium Metabisulfite sold on Dropy India authentic?
Yes, all Duda Energy products available on Dropy India are absolutely authentic. Dropy sources these specialized items directly from reputable suppliers in the United States and imports them to India. This ensures Indian customers receive genuine, high-purity products in their original packaging.
What is the difference between Sodium Metabisulfite and Potassium Metabisulfite?
Both chemical compounds function similarly as stabilizers and antioxidants in brewing and preservation. However, sodium metabisulfite introduces sodium ions into the solution, which may slightly alter flavor profiles or dietary sodium content, whereas potassium metabisulfite adds potassium instead. Sodium metabisulfite is often preferred for strictly sanitizing equipment due to its efficiency.
