Rebaudiosides are a group of natural sweeteners derived from the Stevia rebaudiana plant. Among them, Rebaudioside A 98% stands out for its unique characteristics. As a supplier of Rebaudioside A 98%, I am often asked about the differences between Rebaudioside A 98% and other Rebaudiosides. In this blog, I will delve into these differences to help you make an informed choice.
Chemical Composition and Purity
The most obvious difference between Rebaudioside A 98% and other Rebaudiosides lies in their chemical composition and purity. Rebaudioside A 98% means that the product contains 98% Rebaudioside A, with only 2% being other steviol glycosides or impurities. This high - purity level is achieved through advanced extraction and purification processes.
In contrast, Rebaudioside A 80% contains only 80% Rebaudioside A, and the remaining 20% consists of other steviol glycosides such as Stevioside, Rebaudioside C, and various impurities. Similarly, Rebaudioside A 97% has a purity of 97%, which is slightly lower than Rebaudioside A 98%. And Stevioside RA99 has an even higher purity of 99%, but it also has some differences in taste and application compared to Rebaudioside A 98%.
The purity of Rebaudioside A affects its taste, stability, and functionality. Higher - purity Rebaudioside A generally has a cleaner and more refined taste, with fewer off - flavors associated with other steviol glycosides.
Taste Profile
Taste is a crucial factor when it comes to sweeteners. Rebaudioside A 98% is known for its excellent taste profile. It has a sweet taste that is very similar to sucrose, with a rapid onset and a clean aftertaste. The high purity reduces the presence of the bitter or licorice - like aftertaste that is sometimes associated with lower - purity stevia extracts.
Rebaudioside A 80%, on the other hand, may have a more noticeable aftertaste due to the higher proportion of other steviol glycosides. These other glycosides can contribute to a slightly bitter or astringent flavor, especially at higher concentrations. Rebaudioside A 97% has a taste that is closer to Rebaudioside A 98%, but there may still be a subtle difference in the smoothness and the absence of aftertaste.
Stevioside RA99 has a very high sweetness intensity, but its taste is not exactly the same as Rebaudioside A 98%. Stevioside, which is also present in Stevioside RA99, has a different taste characteristic compared to Rebaudioside A, and this can result in a slightly different overall taste experience.
Sweetness Intensity
Rebaudioside A 98% is highly sweet, being approximately 200 - 300 times sweeter than sucrose. This high sweetness intensity allows for very small amounts to be used to achieve the same level of sweetness as a much larger quantity of sugar.
The sweetness intensity of other Rebaudiosides can vary. Rebaudioside A 80% has a similar basic sweetness mechanism but may have a slightly lower perceived sweetness due to the presence of other non - sweet or less - sweet components. Rebaudioside A 97% has a sweetness intensity that is very close to Rebaudioside A 98%, but again, the small difference in purity can lead to minor variations.
Stevioside RA99 is extremely sweet, even more so than Rebaudioside A 98% in some cases. However, the high sweetness needs to be carefully balanced in applications to avoid an overpowering sweet taste.
Stability
In terms of stability, Rebaudioside A 98% has good stability under a wide range of conditions. It can withstand different pH levels and temperatures, which makes it suitable for various food and beverage applications. The high purity contributes to its stability, as impurities can sometimes cause degradation or chemical reactions under certain conditions.
Rebaudioside A 80% may be less stable because of the higher proportion of other steviol glycosides and impurities. These additional components may react with other substances in the product or be more susceptible to environmental factors such as heat and light. Rebaudioside A 97% has better stability than Rebaudioside A 80% but may still be slightly less stable than Rebaudioside A 98%.
Stevioside RA99 also has good stability, but its high - purity Stevioside component may have different stability characteristics compared to Rebaudioside A, which means that the overall stability profile of Stevioside RA99 in different applications may vary.
Applications
The differences in taste, sweetness intensity, and stability of these Rebaudiosides lead to different application scenarios.
Rebaudioside A 98% is widely used in high - end food and beverage products where a clean, sweet taste and good stability are required. It is suitable for products such as premium soft drinks, fine - dining desserts, and high - quality dietary supplements.
Rebaudioside A 80% is more commonly used in applications where cost is a major consideration and a slightly less refined taste can be tolerated. It can be used in some lower - cost food products, animal feed sweeteners, or in products where the overall flavor profile can mask the minor aftertaste.
Rebaudioside A 97% is a good compromise between cost and quality. It can be used in a wide range of food and beverage applications, including mid - range soft drinks, bakery products, and confectionery.
Stevioside RA99 is often used in applications where a very high level of sweetness is needed in a small volume, such as in concentrated flavorings or some pharmaceutical products.
Regulatory Considerations
All Rebaudiosides, including Rebaudioside A 98%, are subject to regulatory approval in different countries. In general, higher - purity Rebaudiosides are more likely to meet strict regulatory requirements because of their lower impurity levels.
Rebaudioside A 98% has been approved for use in many countries around the world as a natural sweetener. Its high - purity and well - defined chemical composition make it easier to comply with food safety and quality regulations.
Rebaudioside A 80% may face more challenges in some regulatory environments due to the higher impurity content. However, it is still approved for use in many regions where less strict regulations are in place. Rebaudioside A 97% and Stevioside RA99 also need to meet relevant regulatory standards, but their regulatory status may vary depending on the specific composition and the requirements of different countries.
Cost - Benefit Analysis
When considering the use of Rebaudiosides, cost - benefit analysis is essential. Rebaudioside A 98% is generally more expensive than Rebaudioside A 80% and Rebaudioside A 97% due to its high purity and superior quality. However, the benefits in terms of taste, stability, and regulatory compliance can outweigh the higher cost in many applications.
Rebaudioside A 80% offers a more cost - effective solution for some applications where taste is not the primary concern. Rebaudioside A 97% provides a balance between cost and quality, making it a popular choice for many food and beverage manufacturers.
Stevioside RA99, despite its high cost, can be a cost - effective option in applications where a very high level of sweetness is required in a small amount, as only a tiny quantity is needed to achieve the desired sweetness.
Conclusion
In conclusion, Rebaudioside A 98% has distinct differences from other Rebaudiosides in terms of chemical composition, taste profile, sweetness intensity, stability, applications, regulatory considerations, and cost - benefit analysis.
