سبزی پروٹین گوشت کی ترقی کا پس منظر

The world's meat production has grown rapidly in the past 50 years. Compared with the 1960s, the meat consumption of the entire world has increased by 4 to 5 times. Because raising cattle, pigs, sheep, chickens and other domestic animals consumes a lot of energy, more meat appears in human diets, which also affects the environment in which humans live. Climate warming is also related to the increase in global meat consumption. In addition to the food consumed by humans, the total amount of food consumed by pets is also not to be underestimated. In the United States alone, the meat consumed in pet food already accounts for one-third of all meat consumption in the United States. A professor in the Department of Geography at the University of California, Los Angeles has done a study. The results show that because pet foods eaten by pets are mainly high in protein, if your dog eats as much as you, in fact, the dog consumes meat. Much more than you. Animal protein is gradually in short supply, and it has become a trend to seek meat substitutes. "Artificial meat" is a meat substitute that can be produced through scientific and technological means. Its essence is more controllable industrial production, which replaces the meat industry's series of processes from breeding, slaughtering, storage and transportation, which means that "artificial meat" can be It is not affected by environmental pollution and animal diseases, so it is safer and more nutritious, making it more stable and effective in production. At present, "artificial meat" is roughly divided into two types, one is plant protein meat made from plant protein; the other is cell culture meat grown from animal stem cells. Cell culture meat is still in the laboratory stage, and the production cost is high, and large-scale production is difficult; while vegetable protein meat has a market foundation, and the number of commercially available products is increasing year by year.
