Beyond its culinary applications, sodium bicarbonate also plays a role in food preservation. It can inhibit the growth of bacteria and molds, making it a useful additive in extending the shelf life of various products. For instance, some processed foods incorporate sodium bicarbonate to help maintain freshness and prevent spoilage, contributing to food safety and reducing waste.
Another critical factor influencing the price is production and transportation costs. The manufacturing process requires energy and other resources, and any changes in energy prices can affect overall production costs. Additionally, transportation logistics play a vital role in pricing, particularly for regions that are geographically distant from production facilities. Increases in fuel prices or transportation tariffs can lead to higher costs when sodium metabisulfite is delivered to markets, further impacting its pricing.
