Yes, masala pastes can generally be safely prepped and stored in silicone jars. Silicone is non-reactive and food-grade, making it a suitable material for storing various food items, including masala pastes.
Silicone is a synthetic rubber that is known for its heat resistance, flexibility, and non-reactivity. Food-grade silicone is specifically manufactured to be safe for contact with food. When storing masala pastes, the non-reactive nature of silicone is particularly beneficial because it prevents the paste from absorbing any flavors or odors from the container, and vice versa. This ensures that the masala paste retains its intended flavor profile. Furthermore, silicone jars are often airtight, which helps to prevent oxidation and spoilage of the masala paste, extending its shelf life. They are also easy to clean, either by hand or in a dishwasher. However, it's important to ensure that the silicone jar you are using is indeed food-grade and from a reputable manufacturer to avoid any potential leaching of harmful chemicals.
When storing masala pastes in silicone jars, press a piece of plastic wrap directly onto the surface of the paste before sealing the jar. This minimizes air exposure and further prevents oxidation, helping to maintain the paste's freshness and vibrant color for a longer period.
