Want to enjoy delicious food without missing out on nutrition and taste? Try the low-temperature slow cooking machine! Put the ingredients into a high-temperature resistant plastic bag, remove the air to create a vacuum state, and then place it in constant-temperature hot water at a set temperature to slowly soak until thoroughly cooked. In this way, food can release the most sodium glutamate at the optimal temperature, maintaining its original flavor, and its texture and nutrition also reach the best state.
