Pickling and calcium hydroxide

Pickling lime is sometimes used during the pickling process to give pickels an extra crunch. Its a form of food-grade calcium hydroxide. Traditional canning recipes usually suggest soaking freshly sliced cucumbers or other vegetables in pickling lime for 10 to 24 hours before canning them. During this step, the calcium in pickling lime binds to pectin, making it firmer.

Today, many recipes recommend avoiding pickling lime. This is because pickling lime has been linked .

A number of recipes offer alternatives to keep your pickles crunchy. These include soaking vegetables in ice water for four to five hours before pickling or using pickling salt.

Versatile Applications Across Industries

Owing to its alkalinity (pH ~12), Hydrated Lime Powder efficiently regulates pH in water treatment plants, neutralizes acidic effluents, and stabilizes soil in construction projects. Additionally, it's employed in food processing (as E526), agriculture, and chemical synthesis, offering multifaceted benefits tailored to each sector's needs.

Safe Handling and Long Shelf Life

Packaged in moisture-proof HDPE bags and stored in cool, dry conditions, Hydrated Lime Powder maintains stability and effectiveness for up to 24 months when sealed. Though non-poisonous, it is caustic and requires handling with care, as it is classified as an irritant. Always use appropriate personal protective equipment during handling.

FAQ's of Hydrated Lime Powder:

Q: How should Hydrated Lime Powder be stored to maintain its quality?
