Currently, under inflation in various countries, wages have not increased, and people's wallets are shrinking. Everyone has become accustomed to bulk buying at wholesale stores, supermarkets, and group buying websites to reduce ingredient costs and the number of trips made for purchases. However, when the quantity increases, issues such as forgetting items and letting them expire or spoil due to improper storage arise. After careful calculation, it becomes evident that the food thrown away not only causes invisible financial losses but also increases waste and environmental resource depletion. Where does the discarded food go? Wasted food is usually sent to landfills, where it gradually decomposes and produces methane gas, a common greenhouse gas. In other words, throwing away food not only wastes money but also a significant amount of water, as 24% of agricultural water is lost due to food waste each year, leading to severe consequences for climate change. In recent years, experts have called for the adoption of scientific and practical concepts for procurement planning and food preservation to avoid waste and extend the freshness of ingredients, which can be done by both households and individuals. 1. Smart shopping: Make a list of the food items needed and try to strictly adhere to it, which helps reduce impulse buying. 2. Proper and effective storage and management: Many people are unaware of the correct methods for storing ingredients, leading to premature ripening of fruits and vegetables, and spoilage or rot of meat and seafood. Utilizing vacuum preservation technology to extend the freshness of ingredients is a great solution. Vacuum storage can remove air, reduce oxidation, and effectively prolong the shelf life of various ingredients. When a large quantity of ingredients is brought home, use vacuum bags and vacuum boxes to categorize and portion them properly. Take out only the amount needed for each meal, adhering to the "first in, first out" principle, and cook just the right amount for each meal to effectively reduce leftovers. 1. Ingredient repurposing: Pickling, drying, canning, fermenting, freezing, and marinating are all methods to extend the shelf life of food. For example, the traditional Lunar New Year dish, long-lasting vegetables, which are mustard greens, can be transformed into various forms such as heart-shaped mustard greens, snow greens, sauerkraut, and more, depending on the preparation method. Most preservation methods are simple and fun to implement, and they enhance different flavors, showcasing the wisdom of food preservation passed down from ancient times. In recent years, the market has introduced various preservation boxes and bags combined with vacuum preservation technology, allowing for re-vacuuming after each use to maintain better freshness and taste. Coupled with ingredient management tool apps, it becomes even more convenient to record the storage dates and types of food, set recipe reminders for the ingredients bought for specific dishes, and set expiration reminders. Effectively utilizing the carefully budgeted ingredients can significantly reduce waste while ensuring fresh meals. !\[\](https://imageproxy.pbkrs.com/https://pgw.udn.com.tw/gw/photo.php/query-dT1odHRwczovL3VjLnVkbi5jb20udHcvcGhvdG8vMjAyNS8wMi8yMi9yZWFsdGltZS8zMTU0MDkzOC5qcGcmeD0wJnk9MCZzdz0wJnNoPTAmc2w9VyZmdz0xMDUwJmV4cD0zNjAwJmV4cD0zNjAw? The vacuum preservation box paired with app technology helps users more effectively manage and track the freshness of food, thereby reducing food waste.
