Microalgae: The Rising Star of Food Tech
Microalgae have lately gained global interest for their diverse applications in the food industry. Renewable and economical, these tiny powerhouses offer solutions to food security and environmental challenges. With the potential that microalgae offer, understanding the science behind them is important for anyone looking for a job within this sector. So what expertise is required to start a career in this promising field?
What Is Microalgae Protein?
As people become more health-conscious and the global population grows, the demand for protein increases, and the food industry is adapting to producing more protein through sustainable methods. Microalgae are microscopic algae invisible to the naked eye. Known for their high protein content and essential amino acids, they are seen as a potential solution that has a low environmental impact and high nutritional value. An extremely diverse group of organisms, they show a wide range in protein content across species and environmental conditions.
Typically, microalgae have a protein content ranging from 40-60% of dry matter, but some, particularly those cultivated for oil, have lower levels. They can grow in various water conditions without competing for agricultural land and are efficient in carbon dioxide fixation. However, among the 200,000 estimated species, only a few have been researched for human consumption so far.
Some of those have been consumed for centuries, with large-scale cultivation beginning in the mid-20th century. The most utilized species for food proteins and supplements, like Chlorella and Arthrospira, are chosen for their high protein content and essential amino acid profiles. The development of microalgae as a food source is, however, still in the early stages, requiring more research and skilled professionals to optimize cultivation and production for market demands.
