The food and beverage industry has always been highly competitive, with companies constantly striving to create products that stand out on the shelves and win over consumers. The key to success often lies in the sensory appeal of the product – its taste, texture, and appearance. Fat, salt, and sugar have long been the go-to ingredients for achieving the desired sensory qualities. All the things that are perceived to be bad for us! Fat provides a smooth, creamy texture; salt enhances flavour; and sugar offers a quick energy boost and sweetness that many consumers crave. Despite their effectiveness in making food products more appealing, these ingredients have come under scrutiny due to their association with various health issues. High consumption of fat, salt, and sugar has been linked to obesity, heart disease, diabetes, and other chronic conditions. As a result, there has been a growing demand for healthier food options, and governments around the world have started to take action.
While for years there was a push from consumers for healthier options, when governments start to get involved the push becomes a shove. The so-called “sugar tax” was introduced in the UK back in April 2018. The sugar tax, officially known as the Soft Drinks Industry Levy, was introduced to encourage manufacturers to reduce the sugar content in their beverages. This UK tax applies to drinks with more than 5 grams of sugar per 100 millilitres (18p/L) , with a higher rate for drinks containing more than 8 grams of sugar per 100 millilitres (24p/L). Drinks with less sugar avoid the levy entirely. This lead to a wave of innovation and new patent filings. Companies sought to find innovative new ways for their existing brands to avoid these additional costs – it is never as simple as just taking out sugar, and no one wanted to lose customers from changing their product flavour! (see the kerfuffle when Coke reformulated Coca-Cola in 1985!)
This led to companies experimenting with natural sweeteners, flavour enhancers, and other ingredients to maintain the taste and appeal of their drinks. The result was a significant reduction in the sugar content of many popular beverages, demonstrating that legislation can be a powerful driver of product innovation. It also provides a valuable case study for understanding the impact of legislation on product innovation.
We are now seeing further trends in the UK as a direct result of more legislative restrictions. The government brought in legislation on the restriction of products high in fat, sugar, or salt, so-called HFSS legislation (October 2022). This legislation aims to restrict the promotion and sale of products high in fat, sugar, or salt, particularly to children. The goal is to reduce the consumption of unhealthy foods and encourage healthier eating habits. For food manufacturers, this means that they need to reformulate their products to comply with the new regulations while still maintaining their appeal to consumers. There is now a surge of innovation seeking to provide consumers with the products they love, while at the same time meeting these tough new requirements. This recent wave of innovation seems to be more widely cast, not just seeking to reduce sugar contact, but also fat and salt.
One of the key challenges in this process is finding suitable replacements for fat, salt, and sugar. These ingredients play crucial roles in the structure, flavour, and shelf life of food products, and simply removing them can result in products that are less appealing or have a shorter shelf life. Therefore, food scientists are exploring a range of alternatives, including natural sweeteners, salt substitutes, and fat replacers.
Natural sweeteners, such as stevia and monk fruit extract, have gained popularity as alternatives to sugar. These sweeteners provide the desired sweetness without the calories and have a lower impact on blood sugar levels. However, they can sometimes have a different taste profile or aftertaste, which requires careful formulation to ensure the final product is still enjoyable.
Salt substitutes, such as potassium chloride, are being used to reduce sodium content in food products. While these substitutes can mimic the salty taste, they can also introduce a bitter or metallic aftertaste if not used correctly. Balancing the flavour profile is essential to ensure that the product remains appealing to consumers.
Fat replacers, such as protein-based or carbohydrate-based ingredients, are being used to replicate the creamy texture and mouthfeel provided by fat. These replacers can be derived from various sources, including dairy, soy, and oats. The challenge lies in achieving the same sensory qualities without compromising the product’s stability and shelf life.
In addition to ingredient innovation, companies are also exploring new processing techniques to enhance the sensory qualities of their products. For example, advanced emulsification and encapsulation technologies can help improve the texture and flavour release of reduced-fat or reduced-sugar products. These techniques allow for better distribution of flavours and textures, making the final product more appealing to consumers.
Looking ahead, it is clear that legislation will continue to play a crucial role in shaping the food and beverage industry. Governments around the world are increasingly focused on public health and are likely to introduce more regulations aimed at reducing the consumption of unhealthy foods. For food manufacturers, staying ahead of these regulatory changes will be essential for success. Savvy companies will keep a close eye on emerging legislation and use it as a driver for their own product development. By anticipating regulatory changes and investing in research and development, they can create products that not only comply with the new rules but also meet the evolving preferences of consumers. This proactive approach can provide a competitive advantage and help build a reputation for innovation and responsibility.
