A complete protein, by definition, contains all the essential amino acids (EAA), including branched chain amino acids (BCAA). There are nine EAA including: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine.
Complete proteins are usually from animal-based sources of nutrition, and soy as a plant-based source.
Some EEA may be found in plant-based proteins, however, except for soy, these are usually incomplete proteins.
Engevita® HiPRO Beyond is a non-animal source complete protein, containing all EAA and BCAA. Unlike soy, it is non-allergenic.
These are amino acids that humans and other vertebrates cannot synthesize from metabolic intermediates and therefore they must be supplied by the diet.
Without EAA, a food is considered to be nutritionally incomplete. Continued ingestion of foods without EAA will eventually lead to malnutrition and related complications of poor health.
BCAA are essential amino acids and are synthesized in bacteria, plants, and fungi, but not in animals. They include isoleucine, leucine and valine.
The diet is the only significant source of BCAA. They are not only important for proper nutrition but also to stimulate protein synthesis and for muscle building as they contribute to anabolism.
Proteins comprise an important macronutrient in the diet, providing nitrogen and amino acids, which play a role in the synthesis of muscles, hormones, enzymes and other important structural or functional elements of the body.
Protein-rich animal-derived foods, including meat, dairy and egg products are the source of most protein to many populations.
High consumption of protein-rich animal derived products (e.g. beef, pork, lamb) has a detrimental impact on both health and the environment. In addition, the increasing demand of protein, globally, has made eating meat an unsustainable practice.
Transitioning to a more sustainable diet is a way to reduce the environmental footprint while also delivering health benefits to the consumer.
From a food supply perspective in the context of food security, yeast protein is a very interesting alternative protein as its production is independent of the season and can be obtained in a fairly short time. Fermentation could be seen as a new form of farming.
Yeast is also a good source for SCP production due to its superior nutritional quality.
The production of SCP in controlled systems called “bioreactors” is receiving increasing attention from research and industry. Single cell protein has low arable land requirements and does not directly compete with crop-based food commodities.
