Protein – we need it, and we want it. Amping up the protein content of plant-based products is a common struggle for the food industry: how to ensure the availability and digestibility of plant-based protein? Despite the limitations, Apetit’s BlackGrain ingredient makes the most out of rapeseed without compromising nutritional value or taste.
We all need protein to help our bodies to repair cells and make new ones. However, chances are you’re overemphasizing its volume on your plate.
A sufficient daily amount of protein is 0.75 to 0.80 grams per kilogramme of body weight. A diet too high in protein might injure your kidneys and cause other health problems.
Apetit’s Product Development Manager Leticia Valenzuela shares insights on how BlackGrain from YellowFields™ helps adjusting the protein content in recipes while maintaining the nutritional balance.
The global protein megatrend leaves other nutrients in the by-lines
– We need protein as a part of a healthy diet, but the reality is that we’re overconsuming it. Partly because we have so much protein on the market: advancing technology brings out an ever-increasing range of isolates and alternatives to choose from, Apetit’s Product Development Manager Leticia Valenzuela says.
Another reason is the ongoing global protein hype that emphasizes the necessity of protein.
– Consumer demands drive the industry. However, if we focus only on protein, we leave behind fibre, micronutrient components, and minerals, and move away from the core of a healthy diet.
That’s why Apetit’s product development team intentionally aimed to create an ingredient beyond a protein isolate or concentrate.
– We wanted our product to have three indispensable ingredients for health – protein, fibre, and essential fats – and the beauty of maintaining a balanced diet. The resulting plant-based powder ingredient, BlackGrain, does just that, Valenzuela smiles.
Rapeseed has an excellent amino acid profile among plant-based proteins
When switching from animal protein to plant-based alternatives, the characteristics of protein and its digestibility change.
– The multiple components of plant-based protein, such as small micronutrients, tannins, and phenolic compounds, are healthy in moderate doses and contribute to well-rounded nutrition. However, this complexity makes it more difficult for the body to absorb and utilise plant-based protein fully, Valenzuela explains.
The amino acid profile of a protein reveals how well it will be absorbed into the body. If the content of one or multiple essential amino acids is low, they become limiting amino acids, preventing the body from absorbing, and utilising the rest of the amino acids.
– The amino acid profile of rapeseed protein is almost perfect, allowing the body to utilise them more freely. Contrary to soy protein, rapeseed protein isn’t limited by valine or methionine, which are common limiting essential amino acids in legumes.
Pure rapeseed protein isolate has a digestibility between 0.92 to 0.98 out of 1, making it almost fully digested. Even though BlackGrain is made of rapeseed, its digestibility is different due to the matrix including fibres and lipids as well.
– We executed in vitro analysis to understand and demonstrate the protein digestibility and availability in BlackGrain. The study shows that despite the matrix composition, our protein is still readily available for human nutrition, Valenzuela concludes.
BlackGrain maintains or enhances the protein content of food products
While working with texturized vegetable protein (TVP) applications, Valenzuela was surprised to find that adding BlackGrain to a food application won’t diminish the nutritional value of the product.
– However, just as there isn’t a direct conversion of turning a helping of protein into an equal amount of muscle, we can’t say that adding a certain percentage of BlackGrain will lead to an equal amount of protein absorbed by the body, Valenzuela notes.
The protein in BlackGrain is also proven to be quite stable in several food applications from vegetable patties to gluten-free bread.
– These findings give companies opportunities to play with diverse BlackGrain-fueled recipes to achieve regulation-based label claims, such as high in protein, as well as high in fibre.
