Commercial cake preservatives can be classified into two main categories natural and synthetic. Natural preservatives, such as vinegar, lemon juice, and certain essential oils, leverage the antimicrobial properties of their ingredients to inhibit spoilage and extend freshness. On the other hand, synthetic preservatives, including substances like potassium sorbate and calcium propionate, are engineered to provide longer shelf lives and enhanced protection against mold, yeast, and bacteria.
Formaldehyde (CH₂O) is a colorless gas with a pungent odor, widely used in the production of resins, plastics, and various household products. It is also a vital preservative in laboratories and medical settings due to its ability to kill bacteria and fungi. However, formaldehyde is classified as a volatile organic compound (VOC) and is associated with various health risks, including respiratory issues and skin irritation. Moreover, long-term exposure has been linked to cancer, making it essential to monitor its levels in indoor air quality.
In recent years, the price of ammonium bicarbonate has exhibited significant volatility. Factors such as geopolitical tensions, trade policies, and economic conditions have further complicated the landscape. For instance, increased tariffs on imported ammonia may create upward pressure on ammonium bicarbonate prices in certain regions. Similarly, disruptions due to global crises, such as pandemics or export restrictions, can lead to supply shortages that amplify price fluctuations.
