With the growing demand for sustainable and nutritious food sources, alternative proteins are gaining significant attention all over the world. But people today don’t have to be restrictive to only plant-based protein, as more alternatives have entered the food market. Other sources of proteins include fermented proteins, algae, insect protein and cultured meat, besides plant-based proteins. Forecasts estimate that the alternative protein market value will reach 22.95 billion U.S. dollars by 2024, with a compound annual growth rate (CAGR) of 14.1% from 2025 to 2030.

Insect Proteins
If we look at history, insects have been consumed for centuries in various cultures around the world. They are also affordable proteins, all the essential amino acids are present in them, and it is also rich in vitamins and minerals. In comparison to conventional livestock, insects are a sustainable source of protein that use a lot less feed, water, and land, according to the Food and Agriculture Organisation (FAO).
Benefits of Insect Protein:
Challenges:
Insect protein has benefits, yet it is filled with challenges too. In many nations, including India, eating insects is frowned upon. Also, lack of regulatory frameworks in some regions can hinder the commercialization of edible insects.
Lab-Grown Meat
Cultivated meat is meat produced directly from cells. The process of cultivating meat uses the basic elements needed to build muscle and fat and enables the same biological process that happens inside an animal. At the cellular level, farmed meat is the same as cultivated meat. This innovative approach aims to replicate the taste and texture of traditional meat while addressing ethical and environmental concerns.
The first cultivated burger was unveiled in August 2013 by Mark Post and his colleagues at Maastricht University. In 2016, UPSIDE Foods, the first cultivated meat company, was launched publicly.
Benefits of Lab-Grown Meat:
Challenges:
The only drawback with lab grown meat is the cost of production as it uses advanced technology and expensive culture media.
Mycoproteins
Mycoproteins are nothing but fermentation. It is extracted out of the fungus Fusarium venenatum. The microbial cultures were also used to make alcoholic drinks and enhance the nutritional benefits and bioavailability of foods such as yogurt to tempeh, in ancient civilisations in India and elsewhere. Fermentation has a much wider range of uses now than it did in the past century.
Benefits of Mycoproteins:
Challenges:
The biggest issue right now is the price. Because the cells need specialized, high-tech labs and costly growing solutions, large-scale production is still expensive.
