Common preservatives used for urine preservation include boric acid, sodium azide, and hydrochloric acid. Boric acid is effective for preserving urine samples for bacterial culture, while sodium azide helps to prevent bacterial growth by inhibiting enzymatic activity. Hydrochloric acid is used to lower the pH of urine samples to inhibit bacterial growth and degradation of compounds like glucose and proteins.

Two different types of preservatives commonly used in 24-hour urine collections are boric acid, which prevents bacterial growth by acidifying the urine, and thymol, which acts as a fungicide and antibacterial agent. These preservatives help maintain the integrity of the sample for accurate testing over the collection period.
Food preservatives can originate from both natural and synthetic sources. Natural preservatives, such as salt, sugar, vinegar, and certain spices, have been used for centuries to inhibit microbial growth and extend shelf life. Synthetic preservatives, like sorbates and benzoates, are chemically produced to provide more effective preservation. These compounds help maintain food quality by preventing spoilage and extending freshness.
