Patent Application
20220218008
The invention relates to flavor modulating compounds and their use as an additive for food and drink. By blocking/modulating bitter and/or sour flavors, the amount of added sugars and/or salts can be reduced.
There are five primary tastes perceived by the human tongue: salt, sour, sweet, bitter, and umami (i.e., savory). Many people consider the bitter sensation to be unpleasant, and it is speculated that the ability to sense bitterness evolved as an avoidance mechanism against toxic plants and animals. Nevertheless, many foods with high nutritional value, for instance cruciferous vegetables and cranberries, also have bitter flavors. Similarly, foods that are overly sour are not well tolerated by a majority of consumers as well. These foods are often prepared with high levels of fats, sugars, and/or salts in order to mask the bitterness. Although these additives increase the palatability of the nutritious foods, excess consumption of fat, sugar, and salt is considered unhealthy. As an alternative, bitter blocking compounds having been developed as an additive for foods and vegetables. However, different foods have different distributions of bitter compounds, and many additives only block a subset of bitter flavors.
Compounds with sour modulating behavior are even less well known in the literature. In many products such as yogurt or juice, excessive sourness can occur and negatively impact the product quality. Currently the citrus industry in Florida (also California) is in a critical situation with huanglongbing (HLB) or citrus greening disease. Juice produced from HLB infected fruit is low in quality, with increased bitterness and sourness, as well as a poor aroma. Earlier research showed that HLB-induced off-flavor was not detectable in juice made with up to 25% symptomatic fruit in healthy juice. However, increasing the concentration of symptomatic juice presents a detectable and recognizable off flavor. Moreover, in many regions it is increasingly difficult to find fruit not showing HLB symptoms. Although elimination of the causative organism of citrus greening would be the ideal solution, there remains a need for methods of improving the flavor quality of HLB-induced off flavors.
There remains a need for novel compounds that block the bitter and/or sour sensations in foods and beverages. The remains a need for compounds that modulate the aromas of foods and beverages. There remains a need for palatable foodstuffs with reduced sugar and salt additives.
