Novel Protein Foods: Alternative Sources of Protein for Human Consumption

Proteins are a major macronutrient of the human diet needed for 
survival. Its crucial function in nourishment is to provide sufficient amounts 
of amino acids to the body as these amino acids work as anaplerotic 
substrates in the building block of the body. As the growth of population 
increases continuously, the demand for protein also increases over the next 
decades, and it is very important to search alternative sources of protein for 
human consumption. The present food industrialists aim to develop a 
cheaper, protein rich that have almost essential amino acids with highest 
bioavailability and more convenient food products. Single cell protein from 
algae and fungi, leaf protein extract and many insects could be an alternative
of protein, because they have almost all the essential amino acids required 
for the human body for the survival.
