[Model experiments on sorption properties of beet-root fiber]

Area of Science:

• Food Science
• Analytical Chemistry
• Environmental Science

Background:

• Dairy foods can be contaminated with heavy metals such as copper, lead, and zinc.
• Dietary fiber, like that from beetroot, is increasingly studied for its potential health benefits and contaminant-binding properties.

Purpose of the Study:

• To investigate the sorbate properties of beetroot fiber for heavy metal absorption in dairy foods.
• To assess the effectiveness of beetroot fiber in reducing copper, lead, and zinc levels in dairy products.

Main Methods:

• Model experiments were conducted to simulate the interaction between beetroot fiber and heavy metals in a dairy food matrix.
• Sorbate properties were determined through analytical measurements of heavy metal concentrations before and after treatment with beetroot fiber.

Main Results:

• Beetroot fiber demonstrated significant absorption capabilities for copper, lead, and zinc in dairy food models.
• The presence of beetroot fiber led to a measurable reduction in the concentration of these heavy metals.

Conclusions:

• Beetroot fiber can be utilized as a natural agent to mitigate heavy metal contamination in dairy foods.
• Incorporating beetroot fiber into dairy products can enhance their hygienic safety and consumer health protection.
