Beyond being a sweetening agent, E420 offers several potential health benefits that may appeal to consumers seeking healthier alternatives. One notable benefit is that these sugar alcohols do not cause significant spikes in blood sugar levels, making them popular choices for diabetics. Additionally, sorbitol has been studied for its role in dental health; unlike regular sugar, it does not contribute to tooth decay, and in some cases, it may even help in preventing cavities.
Carrageenan is a polysaccharide composed of linear chains of sugar residues, primarily galactose. It is extracted from various species of red algae, most notably from Irish moss and other seaweeds. There are three main types of carrageenan – kappa, iota, and lambda – each with distinct properties that tailor their functionality in food applications. Kappa carrageenan forms strong gels in the presence of potassium ions, while iota carrageenan creates softer gels with calcium. Lambda carrageenan, on the other hand, remains soluble and does not gel, making it suitable for use in products where thickening is desired without gel formation.
On the supply side, the production of phosphoric acid largely depends on the extraction of phosphate rock. Major producing countries, including Morocco, China, and the United States, significantly influence global supply levels. Changes in mining regulations, production practices, or domestic policies in these countries can directly impact the availability of phosphoric acid on the global market, consequently affecting prices.
In culinary applications, sodium bicarbonate is most notably used as a leavening agent. It reacts with acidic ingredients—such as buttermilk, vinegar, or yogurt—to release carbon dioxide gas. This process causes dough and batter to rise, creating a light and fluffy texture in baked goods. For instance, cookies, cakes, and muffins often rely on baking soda to achieve their desired consistency. However, it’s important to measure it carefully, as too much sodium bicarbonate can lead to an unpleasant, soapy taste.
