2. Summary of Presentation Topics
2.3.1. Protein Quality
2.3.3. Bioactive Peptides
3.1. The Opportunity
- Challenges aside, as food companies search for alternatives to soy protein and new plant proteins, an opportunity for canola emerges in the escalating demand for alternative protein sources.
- It is known that canola protein has a well-balanced amino acid profile, with a PDCAAS (canola protein products close to commercial entry level) that is very competitive with other plant proteins currently on the market. However, given the movement of the FAO to the DIAAS (Digestible Indispensible Amino Acid Score) method of evaluation of protein quality, it would be useful to have this measurement for canola protein.
- Canola has brand recognition as a healthy oil that is widely used and accepted in food processing and in the home. This brand acceptance should extend to the protein, although there may be GMO concerns with the protein that we do not see with the oil.
- Positioning of canola protein is very important, whether it be as a concentrate or isolate, and used in food or aquaculture. Unquestionably, the price of the canola protein product will be an important factor in its positioning.
- Opportunities also lie in the potential co-products from canola protein fractionation. These include: hull fibre, higher value protein fractions, lignin, phytic acid, polyphenols and canolol. An accurate techno-economic model is needed to evaluate all the opportunities for canola proteins and co-products.
3.2. The Challenge
- The biggest factor determining the success of canola protein as a food ingredient is being able to bring a product to market at a competitive price. The first step in this process is a thorough understanding of the potential market, including: market size, value of the product, price of feed stock, etc. Canola proteins will need to move into higher value markets (or the high volume markets, e.g., breakfast cereals) so the price and market size for higher value proteins need to be accurately assessed. In addition, price targets for production need to be identified.
- It would be necessary to identify the competitive advantage of canola proteins and develop strategies to market these competitive advantages effectively.
- Availability of a suitable feed-stock for protein extraction is a challenge. Conventionally processed canola meal which has gone through a desolventizer-toaster is not an efficient starting material for protein recovery. Currently, there isn’t a viable oil extraction technique that can replace this process without using solvent. Possible solutions are a low temperature desolventizer or vacuum desolventizer, but these would require expensive retrofitting of canola processing plants. Expeller pressing is an alternative oil extraction process, but if a cold-pressing process is used, the meal that is generated is too high in residual oil. Expeller pressed meal with low oil content has highly interacted protein somewhat similar to desolventizer-toasted meal. Although cold-pressed meal can be utilized for further recovery of oil, protein and other co-products, the economics of the technology and products needs to be competitive.
- Current technologies for obtaining canola products target generating protein ingredients to replace widely used proteins, especially those of animal origin. This approach limits options of using existing feed stock materials because some of the delicate functional properties of the final product become a key consideration. With the changing landscape of protein-rich products and how they are consumed (e.g., emulsion-type meat products with plant proteins vs. protein enriched, non transparent drinkable products), technologies need to be developed to use existing canola protein feed stock.
