Truffle Cultivation Medium Using Edible Ingredients for Antioxidant Capacity
Solution Overview
Problem
Conventional truffle cultivation methods do not effectively enhance the antioxidative capacity of truffle mycelium and fruiting bodies, and the traditional culture medium lacks remarkable antioxidative properties, limiting their use as health-promoting food ingredients.
Innovation Solution
A medium comprising a mixture of rice bran and edible ingredients like burdock, nuts, or berries with a specific weight ratio, replacing sawdust, which increases the reactive oxygen scavenging capacity of truffle mycelium and fruiting bodies, making them more suitable for health-promoting food products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional truffle cultivation methods using sawdust-based medium are used, then truffle fruiting bodies can be produced, but the antioxidative capacity of the truffle mycelium and fruiting bodies is insufficient
Solution Approach 1:
The patent changes the chemical composition parameters of the culture medium by replacing sawdust with edible ingredients rich in antioxidants (burdock, nuts, berries) and adjusting the weight ratios of carbohydrate sources to enhance the antioxidative capacity of the cultivated truffles
Solution Approach 2:
The patent creates a composite culture medium by combining multiple edible ingredients (carbohydrate source, burdock, nuts, berries) with specific weight ratios to achieve synergistic antioxidant effects while maintaining truffle cultivation efficacy
2Ease of operation
If sawdust is used in the culture medium, then the medium structure is maintained, but the truffle mycelium cannot be completely isolated from inedible elements
Solution Approach 1:
The patent removes the inedible sawdust component from the culture medium, extracting only the essential structural and nutritional functions, thereby enabling complete isolation of edible truffle mycelium while maintaining medium stability through alternative edible ingredients
3Productivity
If conventional cultivation methods are used, then truffle fruiting bodies are produced, but subsequent post-processing is required to remove inedible elements
Solution Approach 1:
The patent eliminates the need for post-processing by removing inedible sawdust from the medium composition, allowing direct harvesting of pure edible truffle mycelium and fruiting bodies without additional separation steps
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 new medium significantly enhances the antioxidative potency of truffle mycelium and fruiting bodies, allowing them to be used as high-value functional food ingredients with improved health benefits.
Implementation Method 1
The reactive oxygen has been considered as one of the contributory factors for aging and diseases. In recent years, it is believed to be desirable to restrain or eliminate it. The known components to remove the reactive oxygen are, for example, β-glucan polysaccharide, vitamin C, Vitamin E, Saponin, Catechin, Flavonoid, Tannin, β -carotene, Polyphenol, Anthocyanin, etc.

AI summary
The purpose of the present invention is to provide the truffle mycelium and fruiting body cultivated by the medium that are developed for cultivating the truffles with a very high radical oxygen scavenging capacity. A medium for cultivating truffles, said medium comprising a mixture of at least one carbohydrate source selected from the group consisting of rice bran, wheat bran, and glucose, and at least one edible ingredient selected from the group consisting of burdock, nuts, and berries, wherein the weight ratio of said edible ingredient to said carbohydrate source is comprised between 0.5 and 5. As for one of the ingredients, it is preferable that the burdock is granulated. The medium may exist in a liquid state. By injecting truffle seeds for cultivation into such a medium, the truffle mycelium and fruiting body with the high reactive oxygen scavenging capacity could be provided.
