What are Alternative Proteins?
Sourced from different protein-rich ingredients, alternative proteins can be plantbased, cell-based, and insect-based. Insects, animal, and plant-based proteins are good sources of protein, and it is important to blend them to ensure that the product delivers all the essential amino acids dogs and cats need. Consumer views and needs for the end product are being reflected in the commercialization of these alternatives with better and enhanced sensory qualities. Pet food manufacturers now increasingly strive to simplify labels and include ingredients perceived as simpler, cleaner, and more sustainable, offering specialized nutritional support. There is continuous research going on to match the taste and texture of these non-traditional protein sources with the traditional ones.
Yes to Yeast
Algae, yeasts and fermented proteins are some examples of novel protein sources in pet foods and treats.
Tom Asquith, director, research and development, The F.L. Emmert Co. commented in an interview, “Many pet food companies are embracing brewer’s yeast as a rich source of protein, indispensable amino acids, vitamins and beta-glucans. It satisfies nutrition and marketing needs for vegan/nonanimal, sustainable, local and edible diets.” The protein content of dried brewer’s yeast ranges from 35% to 48% with relatively low amounts of fat (2% to 3%) and ash (5% to 8%). Essential amino acid content is comparable to dried egg products. This unique composition enables formulators to boost protein levels in high-meat diets as well as in diets with higher-ash content, he pointed out. Published studies also show that beta-glucans in brewer’s yeast boost gut immunity and can improve gut function.
Canadian-based pet food brand Nature’s Hug, has been working with biotechnology to make animal-free and protein-rich pet food. It has incorporated in its formulas a mycoprotein, proteinNH+ which has similar properties to those of animal protein.
Instead of using large amounts of water, land, and feed to raise livestock for over a year, the proteinNH+ is grown in a fermenter in less than 24 hours to a product that is nutritionally complete.
Nature’s Hug alternative protein generates very little GHG (greenhouse gas) emissions compared to animal production and they use fewer natural resources to produce it.
