Monascus purpureus Strain Ester Production for Cheese Flavor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cheese production methods fail to significantly improve the flavor profile of cheese, particularly for Chinese consumers who prefer milder flavors, as existing Monascus fermented cheeses retain strong pungent odors despite enhanced nutritional value.
Innovation Solution
A Monascus purpureus strain with high esters producing activity is developed, which metabolizes fatty acids into ester compounds like ethyl butyrate, providing a milky or fruity flavor and reducing pungency, combined with methyl ketones for a complex, pleasant flavor profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional cheese production methods are used, then nutritional value is maintained, but flavor profile remains pungent and unappealing to Chinese consumers
Solution Approach 1:
The patent introduces Monascus purpureus as an intermediary microorganism that mediates the conversion of fatty acids into esters. The fungus acts as a biological catalyst that transforms pungent fatty acid compounds into pleasant-smelling ester compounds, thereby resolving the contradiction between maintaining nutritional value and improving flavor profile without requiring complex production method changes
Solution Approach 2:
The patent changes the biochemical parameters within the cheese by introducing Monascus purpureus, which alters the chemical composition by converting fatty acids into esters. This parameter change transforms the flavor profile from pungent to fruity and creamy, making the cheese more appealing to Chinese consumers while preserving its nutritional benefits
2Quantity of substance
If ester content is increased to improve flavor, then pungency is reduced, but production complexity increases
Solution Approach 1:
The patent employs Monascus purpureus to perform the esterification process automatically within the cheese matrix. The microorganism self-generates the necessary enzymes and metabolic pathways to convert fatty acids into esters, eliminating the need for external catalysts, complex reaction vessels, or multi-step processing equipment, thereby increasing ester content without proportionally increasing production complexity
3Shape
If Monascus strain with high pigment production is used, then appearance is improved, but ester production and flavor enhancement are insufficient
Solution Approach 1:
The patent selects a Monascus purpureus strain that exhibits local quality optimization - it maintains the characteristic red pigmentation that improves cheese appearance while simultaneously possessing enhanced ester production capabilities that reduce pungent flavor. This specific strain configuration allows both appearance and flavor properties to be improved concurrently without compromise
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The strain significantly enhances both aroma and nutritional quality of cheese, making it more appealing to Chinese consumers by creating a gentler, fruity, and creamy flavor profile.
Implementation Method 1
A Monascus purpureus strain with high esters producing activity is developed, which metabolizes fatty acids into ester compounds like ethyl butyrate, providing a milky or fruity flavor and reducing pungency

AI summary
The invention discloses a strain of Monascus purpureus with high esters producing activity and the application in the production of ester flavored Monascus cheese. The strain was deposited in China General Microbiological Culture Collection Center (CGMCC) on Oct. 17, 2019, with the preservation number of CGMCC 18589. The strain can make the cheese flavor having less pungent, and richer, significantly improve the odor quality of cheese, thus more in line with the taste of Chinese people. Moreover, some secondary metabolites responsible for health benefits including hypolipidemia, antihypertensive, antioxidant, and antihyperglycemic effects and prevention of obesity and diabetes development have been recognized in Monascus-fermented cheese.
