Rising Sugar-Reduction Reformulation Increases Demand for High-Intensity Natural Sweet Protein

Food and beverage manufacturers are increasingly adopting the strategy of reducing processed sugar in their products and replacing it with natural products. Companies are forced to adopt this product reformulation strategy to reduce added sugar due to increasing awareness among consumers about the negative impact of processed sugar on health. The WHO (The World Health Organization) has also published a health advisory and suggested consumers limit free sugars to below 10% of total energy intake and suggested food and beverage companies reformulate their products. As sweet proteins such as thaumatin, brazzein, and monellin can provide high sweetness, they are gradually being used to develop reduced-calorie products. Moreover, such products complement existing sweetening systems such as Stevia and other naturally derived sweeteners and also cater to health-conscious consumers. Consumer preference for natural ingredients is encouraging food and beverage manufacturers to evaluate sweet proteins as alternatives or complements to conventional high-intensity sweeteners. Therefore, growing scrutiny over the use of processed sugars and increasing demand for commercially standardized sweet proteins is boosting the natural sweet protein market growth.

MARKET RESTRAINTS

High Production Costs Limit Large-Scale Commercial Adoption

The key barrier impacting the market growth is the complex manufacturing process of these proteins. Different proteins require different production processes, and this can influence the manufacturing and production cost. Lack of technical knowledge among the workers can also impact production, leading to costly production and poor recovery of the products. As each product needs to be scrutinized and developed using different methods, the overall formulation costs may increase. Therefore, the sensory benefits of these products are offset by the high costs associated with producing and purifying sweet proteins extracted from natural sources, thereby limiting their production.

MARKET OPPORTUNITIES

Regulatory Progress for Natural Sweet Protein Expands the Commercial Sweet-Protein Portfolio

As regulatory barriers on precision-fermented sweet proteins are reducing, it creates a significant opportunity for manufacturers to diversify the application of such products across different sectors. Such favorable regulatory policies enable manufacturers to increase their investment in developing new products, push toward the development of new products, increase application trials, and establish commercialization agreements with relevant suppliers in key markets.
