In the heart of Okinawa, Japan, a sweet revolution is brewing, one that could redefine the way we think about processed brown sugar. Yonathan Asikin, a researcher from the Department of Bioscience and Biotechnology at the University of the Ryukyus, has been delving into the intricate world of sugar blending, and his findings could have significant implications for the food industry.
Asikin’s research, published in the journal Foods, focuses on the effects of blending non-centrifugal cane sugar (NCS) with raw sugar on the flavor and retronasal olfaction profiles of processed brown sugar. The study, which is the first of its kind, provides a comprehensive analysis of how different blending ratios affect the color, non-volatile and volatile compounds, and sensory profiles of the final product.
The study revealed that as the proportion of raw sugar increases, the processed brown sugar becomes lighter in color, with a less intense brown hue. This is due to the reduction in molasses content, which is responsible for the darker color of conventional NCS. “The addition of raw sugar causes a cascade of interconnected changes in the physical, chemical, and sensory properties of processed brown sugar,” Asikin explained.
But the changes don’t stop at color. The study also found that raw sugar addition significantly reduces the concentration of non-volatile compounds, such as glucose and organic acids. This, in turn, affects the formation of volatile Maillard reaction products (MRPs), which are crucial for the aroma and flavor of the sugar.
MRPs, such as pyrazines, furans, and furanones, are formed during the heating and evaporation processes of sugar production. They are responsible for the distinctive roasted aroma and richness that are characteristic of conventional NCS. As the raw sugar proportion increases, the concentrations of these MRPs decrease, leading to a reduction in the in-mouth and in-nose retronasal aroma release.
The sensory profiles of the processed brown sugar also reflect these changes. Sugars with a higher raw sugar content were found to have reduced intensities of roasted aroma, richness, and aftertaste. On the other hand, sugars with a higher NCS content were darker in color and had greater roasted aroma and richness, affecting the overall flavor quality.
So, what does this mean for the food industry? Asikin’s research provides valuable insights into the complex interplay between raw sugar and NCS in the production of processed brown sugar. It highlights the importance of maintaining a critical balance between the two to achieve optimal sensory appeal and consumer acceptance.
For sugar producers, this study underscores the need to pay close attention to the blending ratios of raw sugar and NCS. It also provides a roadmap for developing new types of brown sugar products with adjustable quality traits, while retaining some of the characteristics of traditional NCS.
Asikin’s work is a testament to the power of scientific research in driving innovation in the food industry. It opens up new possibilities for product development and formulation, and could pave the way for a new generation of processed brown sugars that cater to the evolving tastes and preferences of consumers.
In an era where consumers are increasingly discerning about the quality and origin of their food, Asikin’s research offers a glimpse into the future of sugar production. It is a reminder that even the most seemingly simple products, like sugar, are the result of complex processes and interactions. And as our understanding of these processes deepens, so too will our ability to create products that are not just delicious, but also sustainable and responsive to the needs of consumers.
