Ganoderma lucidum, this precious fungus known as the "fairy grass", has occupied an important position in the traditional medicine and food culture of China, Japan and other Asian countries since ancient times. In 2023, it was officially included in the list of Chinese medicinal and food sources, demonstrating its unique value. But did you know that fresh Ganoderma lucidum perishes easily and must be processed to preserve it, and how does the processing change its flavor? The scientific research team of Zhejiang Shouxiangu Pharmaceutical Co., Ltd. collaborated with Academician Sun Baoguo of the Chinese Academy of Engineering to conduct research, and the results were published in the magazine "Food Chemistry", which for the first time systematically revealed the flavor secrets of Chinese Ganoderma lucidum and its processed products.

Academician Sun Baoguo is a professor and doctoral supervisor at Beijing Technology and Business University, an expert in spices and food additives. He is a contracted academician of Zhejiang Shouxiangu Pharmaceutical Co., Ltd. Functional Food and Nutritional Health Research Institute. He has cooperated with Zhejiang Shouxiangu Pharmaceutical Co., Ltd. to develop a Ganoderma health wine - Yi·Jiuling Wine.

The flavor transformation of Ganoderma lucidum: from fresh to processed

Imagine that freshly picked Ganoderma exudes a rich mushroom aroma and earthy aroma, while Ganoderma products that have been dried, crushed or extracted present completely different flavors - sweet caramel aroma, deep woody aroma and mellow sauce aroma. This change in flavor is the result of complex changes in internal substances during processing.

Researchers found through professional sensory evaluation:

· Fresh Ganoderma lucidum: The dominant flavor is mushroom and earthy aroma

· Dried Ganoderma lucidum: presents a stronger woody, caramel and sweet aroma

· Ultra-fine powder and extract: the sauce, caramel and sour aroma are more prominent

Scientific Detective: Following the Trail of Flavor Molecules

In order to accurately identify the science behind these flavor changes, researchers acted as "flavor detectives" and used a series of cutting-edge technologies:

Gas chromatography-mass spectrometry is like a high-precision "chemical radar" that can separate and identify trace amounts of volatile compounds in samples. The study found that the number and concentration of volatile substances in processed Ganoderma increased significantly, from 52 in fresh Ganoderma to 105 in ultrafine powder.

Gas chromatography-smell-mass spectrometry is even more magical - researchers "smell" the compounds separated by the chromatography column through a special port to directly determine which substances actually contribute to the aroma.

Aroma extract dilution analysis is similar to a "flavor dilution tasting" in which the relative importance of each aroma component is determined by gradually diluting the extract until a certain aroma disappears.

Dive Deeper: Identifying Key Flavor Substances

The study ultimately identified 85 active aroma compounds, 29 of which were confirmed to contribute significantly to the overall flavor. Let’s get to know the key flavors:

1-Octen-3-ol: The "soul ingredient" of fresh Ganoderma lucidum, which produces the typical mushroom aroma. Like a delicate artist, it decomposes when exposed to heat, which explains why the aroma of Ganoderma lucidum diminishes after processing.

Maltol and 5-hydroxymethylfurfural: The "sweetness ambassadors" of processed Ganoderma lucidum mainly come from the Maillard reaction (reaction of amino acids and sugar under heating conditions), giving the product a caramel-like sweet aroma.

Acetic acid and isovaleric acid: Provide pleasant sour and soy aroma, enriching the flavor of Ganoderma lucidum.

To confirm these findings, the researchers conducted an ingenious validation experiment:

Flavor reconstruction: The identified key aroma compounds were mixed in their original proportions to successfully simulate a flavor profile that is very similar to real Ganoderma lucidum.

Missing experiments: Like a jigsaw puzzle, remove one compound from the mixture one at a time and observe the flavor changes. When 1-octen-3-ol was removed, the mushroom aroma was significantly reduced; when maltol was removed, the sweet aroma was significantly reduced—a direct testament to the key role of these ingredients.

Ganoderma Flavor Wheel: A Scientific Map of Sensory Experiences

Based on all the research findings, the team created the "Chinese Ganoderma Flavor Wheel", which summarizes Ganoderma's complex flavor into five basic categories:

· Earthy aroma: mushroom aroma, earthy aroma (representative substance: 1-octene-3-ol)

· Woody aroma: woody aroma (representative substance: naphthalene)

· Sweet aroma: caramel aroma, sweet aroma (representative substances: maltol, 5-hydroxymethylfurfural)

· Floral aroma: Floral aroma (representative substance: phenylacetaldehyde)

· Sour aroma: sour aroma, sauce aroma (representative substances: isovaleric acid, acetic acid)

From lab to life: practical implications of research

This research not only satisfies scientific curiosity, but also has important practical value:

Quality Control: Manufacturers can now precisely control processing and ensure consistent product quality by monitoring the levels of key flavor compounds.

Product Development: Provides clear direction for the development of new flavor-oriented products, such as better-tasting Ganoderma drinks or functional foods.

Consumer Choice: Help consumers better understand and choose Ganoderma lucidum products that suit their tastes, whether they like the original flavor of fresh mushrooms or prefer the sweet aroma of processed caramel.

This groundbreaking research systematically decoded the flavor code of Chinese Ganoderma lucidum for the first time, advancing Ganoderma lucidum from traditional "efficacy recognition" to a new level of "flavor recognition". As the researchers put it: "This work provides a theoretical basis for Ganoderma processing and new product development."

This research not only laid a solid foundation for the standardization and upgrading of the Ganoderma lucidum industry, but also provided strong scientific support for relevant companies to build core technological advantages in the future market and win the favor of consumers.
