With science and technology, human beings will not go hungry. Why do you say that? As we all know, the world population is increasing day by day, while the cultivated land area is decreasing year by year. The food problem is a big problem! However, Yuan Longping, the "father of hybrid rice", solved this world problem. He cultivated hybrid rice by using the basic laws of genetics, and the yield ranged from 400 kg to 600 kg and then to 800 kg, which was amazing and brought good news to mankind, and was known as "Oriental magic rice". Isn't this the "magic" of technology?
Technology has enriched the human dining table. According to my mother, it is very unusual for dishes of all seasons to appear on the table at the same time. But with the popularization of greenhouse planting technology, it is easy to eat vegetables in other seasons now. In the past, northerners wanted to taste tropical fruits, which was an anecdote throughout the ages. That's why the story of "riding a princess in the world of mortals and laughing, no one knows it's litchi" has been passed down to this day. Now with the improvement of food storage technology and food transportation speed, ordinary people can also have Yang Guifei's "luck to eat"!
With the continuous improvement of living standards, people are no longer satisfied with monotonous food, so food processing technology came into being. Food processing takes some edible things as raw materials and makes better or more nutritious food through scientific and technological means. For example, my favorite ham sausage is made of livestock and poultry meat as the main raw material, supplemented by fillers, condiments, spices and other substances, and is made by curing, chopping (or emulsifying), high-temperature cooking and other processing technologies, which is fresh, tender and refreshing and convenient to eat. There are many kinds of food processing, such as condiment processing, fruit products processing, aquatic products processing, dairy products processing, bean products processing, vegetable products processing, etc., which meet the human pursuit of food to a certain extent.
Technology has also "armed" our kitchen. Rice cookers, microwave ovens, ovens, induction cookers, juicers and other kitchen utensils have gradually entered thousands of households, making it more convenient and diverse for people to cook delicious food.
This is the change of "eating" brought by technology. Technology exists in our daily life, and technology is around us!
