With the improvement of people's living standards, sweet potatoes are becoming more and more popular as a nutritious food. However, during the processing of sweet potatoes, a large amount of sweet potato residue is produced, which is often disposed of as waste, resulting in a lot of waste. In fact, sweet potato pomace is a very valuable resource, and with a little treatment, waste can be turned into treasure.
1. The nutritional value of sweet potato residue.
Sweet potato pulp is a by-product of sweet potato processing and is rich in nutrients such as dietary fiber, protein, minerals and vitamins. Dietary fiber can help regulate intestinal function, promote digestion and excretion; Protein is an essential nutrient for the human body and is very important for growth, development and maintenance of good health; Minerals and vitamins also have a variety of benefits for the human body. Therefore, turning sweet potato pomace into treasure not only reduces environmental pollution, but also provides people with a healthy food**.
Second, the utilization of sweet potato residue.
1.Sweet potato pomace is fermented to make alcohol.
Sweet potato pulp contains a lot of starch and sugar, which can be made into alcohol through the fermentation process. This method can not only make full use of the starch and sugar substances in sweet potato pulp, but also produce a renewable energy source that provides convenience for people's production and life. During the fermentation process, it is necessary to add the right amount of yeast and control the temperature and humidity to ensure the smooth progress of the fermentation process. The alcohol produced can be used as fuel, chemical raw materials, disinfectants, etc., and has a wide range of application prospects.
2.Sweet potato residue as feed.
Sweet potato pulp is rich in nutrients such as protein, minerals, and vitamins, and can be made into a nutritious feed after proper processing. This feed can be used in the aquaculture industry to provide the necessary nutrients for the farmed animals and promote the growth and development of the animals. At the same time, making sweet potato pulp into feed can also reduce waste emissions and reduce environmental pollution. In the process of making feed, it needs to be properly processed, such as drying, crushing, mixing, etc., to ensure the quality and safety of the feed.
3.Application of sweet potato pulp in food processing.
Sweet potato residue can be used as a food raw material in food processing such as pastries and bread. Since sweet potato residue is rich in dietary fiber and nutrients, adding it to food can improve the nutritional value and taste of food. For example, sweet potato pulp can be added to bread to create a bread rich in dietary fiber, which is perfect for the health needs of modern people. When applying sweet potato pulp in food processing, it is necessary to pay attention to controlling the amount of addition and undergo proper processing to maintain the quality and safety of the food.
III. Conclusion. As a kind of waste, the utilization value of sweet potato residue has been gradually recognized and explored. Turning sweet potato pomace into treasure in a variety of ways can not only reduce environmental pollution, but also provide a variety of beneficial products for people's production and life. With the continuous progress of science and technology and the expansion of application fields, the utilization and value of sweet potato residue will be further excavated and improved. Let's work together to turn waste into valuable products and contribute to sustainable development.
