Effect of Salt Content Reduction on Food Processing Technology.

Area of Science:

• Food Science
• Nutrition Science
• Food Technology

Background:

• High salt intake is linked to cardiovascular and kidney diseases, hypertension, and gastric cancer.
• Salt reduction is a key public health strategy for improving overall well-being.
• Alternative salt solutions, including substitutes and processed herb homogenates, are explored.

Purpose of the Study:

• To investigate the impact of salt reduction on various food products.
• To identify necessary modifications in food processing for successful salt reduction.
• To understand the effects on sensory attributes, microbial activity, and shelf life.

Main Methods:

• Analysis of salt reduction effects on cheese, bakery, and meat products.
• Evaluation of changes in texture, pH, taste, aroma, and shelf life.
• Assessment of modifications needed in emulsifying salts, starter cultures, and processing techniques.

Main Results:

• Salt reduction alters cheese texture, aroma, microbial diversity, and ripening.
• In bakery products, reduced salt affects dough properties, gluten, yeast activity, and crumb structure.
• Meat product quality is impacted through changes in protein solubility, water binding, and color.

Conclusions:

• Salt reduction necessitates significant adjustments in food formulations and processing.
• Maintaining product quality and safety requires careful modification of ingredients and cultures.
• Strategic salt reduction can be achieved across diverse food categories with appropriate adaptations.
