Product Description

Manufacturers of food-grade calcium hydroxide flour improvement special purpose

Manufacturers specializing in food-grade calcium hydroxide offer this premium additive for flour improvement purposes. As a key functional ingredient, food-grade calcium hydroxide (also known as slaked lime) plays a vital role in enhancing the quality and performance of flour-based products.

 

In flour processing, it acts as a pH regulator and dough strengthener, improving the elasticity and texture of dough for noodles, bread, and pastries. By adjusting the flour's acidity, it stabilizes gluten structure, allowing for better water absorption and (ductility) during kneading and shaping. This not only enhances the final product's appearance and mouthfeel but also extends its shelf life by inhibiting microbial growth.

 

Moreover, as a calcium fortifier, it enriches flour with essential dietary calcium, meeting nutritional requirements for fortified foods. Compliant with international food safety standards (e.g., FDA, EU regulations), this food-grade calcium hydroxide ensures safe and reliable use in commercial flour milling and food production. Manufacturers provide tailored solutions to optimize flour quality, supporting the development of high-performance, nutritious baked goods and pasta products.
