Instead, pouches are filled with puree, placed into a high-pressure chamber, and pressurized to kill bacteria. These pouches are not heated during production. The newest way to make pouch baby food is called HPP, which stands for High Pressure Pascalization. High Pressure Pascalization (HPP): what it is and why we don’t use it We do not use this method because we want to preserve maximum nutrition and only use savory, nutrient-dense ingredients that are typically not as acidic. This process also significantly damages vitamins as they are “boiled off” during the process prior to filling the pouch. This process requires the puree to have a high acid content, which can only be achieved by adding ingredients like fruit, tomato, lemon juice, or citric acid. The traditional (and cheapest) method of making pouched baby food is called hot fill, where purees are boiled for a long period of time before being filled into the pouch. ![]() Hot Fill: what it is and why we don’t use it Once cooled, pouches are placed into boxes and shipped out to retailers or homes like yours! Alternative Ways to Make Pouch Baby Foods Vitamins are naturally slightly harmed whenever they are heated, but studies have shown that pressure cooking preserves more vitamins than any other cooking method. ![]() The fat, protein, fiber, carbohydrates, and minerals are 100% intact. Similar to home canning, this process kills any bacteria and allows the baby food to be shelf-stable without the need for preservatives or refrigeration. Water and steam is pumped into the retort and pouches are processed with the right combination of pressure, heat, and time to create shelf stability. Once the pouches are filled, they are arranged on a cart that’s wheeled into a retort, which is basically a very large pressure cooker. The mixture is pureed and pumped into BPA-free pouches specifically designed for this process. These ingredients are shipped frozen to our factory where they blend these ingredients in small batches and warm them up to a non-boiling temperature.
