The protein ingested by the human body can be divided into two categories: animal protein and plant protein. Animal protein is more easily absorbed by the body, and also contains essential amino acids, but its deficiency is that the saturated fatty acids contained will affect the heart and brain blood vessels. Excessive intake may increase the risk of coronary heart disease. With the improvement of people's quality of life, the demand for protein is also increasing, but the protein production gap is still large, so people began to pursue different sources of protein-plant protein. According to professional institutions, the plant protein market will grow rapidly in the next 10 years. By 2030, the size of the global plant protein market will soar from the current US $ 4.6 billion to US $ 85 billion. The rich nutritional content of algae foods and other health-related factors are driving the development of its global market. Algal protein will be an important raw material for protein foods in the future. The study found that edible algae contains the eight essential amino acids of the human body, and has a reasonable composition, and has an adjuvant treatment effect on various diseases such as hypertension, diabetes, cancer and so on. Similar to traditional sources such as soybeans, whey, and peas, algae protein has a huge appeal in the nutritious food industry because of its rich nutrients. https://eu.echemi.com/info/with-the-growth-of-plant-protein-algal-protein-will-gain-more-attention_103707.html
