Calcium Hydroxide (Food Grade): The Purity of Slaked Lime by Vigyan Lime

In the food industry, precision and safety are paramount. Calcium Hydroxide, commonly known as Slaked Lime or Hydrated Lime, is a versatile inorganic base essential for everything from traditional food preparation to modern nutritional fortification.

At Vigyan Lime, we manufacture a superior Food Grade Calcium Hydroxide (¹ $Ca(OH)_2$ ) that is a free-flowing, super-fine, and ultra-white powder, meticulously processed to meet global safety standards like FSSAI, USP, and ISO.

Technical Excellence & Specifications

Our Food Grade Slaked Lime is processed using ultra-modern methodology to ensure it is free from grits, allergens, and toxic contaminants.

High Purity: Minimum 95% to 98% $Ca(OH)_2$ content.
Ultra-Low Heavy Metals: Lead (Pb) < 2 ppm and Arsenic (As) < 1 ppm, ensuring it is safe for direct human consumption.
Fine Texture: Typically passes through a 200 mesh, ensuring a consistent smooth texture for food processing.
Chemical Profile: Molecular Weight of 74.09 g/mol with a characteristic alkaline taste and a pH level of 12.4.

Versatile Applications in the Food Industry

Vigyan Lime’s Calcium Hydroxide is a vital additive used across various sectors:

Acidity Regulator: Effectively balances pH levels in beverages and processed foods.⁵
Calcium Fortification: Adds essential calcium to fruit juices, infant formula, and health supplements.
Nixtamalization: Traditionally used in processing corn (maize) to enhance nutritional value and flavor.
Baking Substitute: Often used as a safe substitute for baking soda in specific traditional recipes.
Pickling Agent: Helps maintain the firmness and crunch of preserved vegetables.

Why Vigyan Lime Stands Out?

With over 75 years of mastery and a strategic presence in India’s premier mineral belts like Jodhpur and Uttarakhand, we offer:

Good Manufacturing Practices (GMP): Our products are non-toxic and free from non-kosher ingredients.
Secure Packaging: Available in 25 kg/50 kg HDPE bags with inner liners to prevent moisture absorption.
Global Reach: We are a trusted manufacturer, exporter, and wholesaler serving both domestic and international markets with a supply ability of 1000 Kg per day.

Frequently Asked Questions (F&Q)

Q1: What is the shelf life of Food Grade Calcium Hydroxide?

Ans: When stored in a cool, dry place in its original tightly sealed HDPE bag, our product has a shelf life of up to 24 months.

Q2: Is Vigyan Lime Calcium Hydroxide safe for infant food?

Ans: Yes. Because we strictly control heavy metals (Lead < 2 ppm), our food-grade lime meets the safety requirements for sensitive applications like food fortification.

Q3: How is it different from industrial-grade Hydrated Lime?

Ans: Food Grade lime undergoes much more rigorous refining. It has higher purity (min 95%) and significantly lower levels of heavy metals and insoluble grits compared to industrial grades.

Q4: What are the main uses beyond the food industry?

Ans: While this is a Food Grade product, the same high purity makes it excellent for Pharmaceutical APIs, Cosmetics, and High-end Water Treatment where purity is non-negotiable.
