Solution Overview

Problem

Existing methods for meat maturation, such as 'wet-aging' and 'dry-aging,' face challenges with weight loss, flavor concentration, and tenderness, while accelerated methods using mold Thamnidium elegans do not satisfy demanding meat connoisseurs in terms of taste and tenderness.

Innovation Solution

A method involving the use of microorganisms like Penicillium nalgiovense, Penicillium chysogenum, Penicillium gladioli, Penicillium camemberti, and Thamnidium elegans during meat maturation, stored at specific temperature and humidity levels, without additional salt, to enhance tenderness and flavor development over an extended period without altering the meat's internal structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If dry-aging is used to improve aroma and flavor concentration, then meat loses weight due to water evaporation and requires cutting off dried surfaces, but wet-aging preserves weight through vacuum packaging

Engineering Contradiction:
Improvearoma qualityVSAvoidmeat weight
Core Design Contradiction:
Object-generated harmful factorsVSLoss of substance

Solution Approach 1:

The patent changes the physical state parameters by controlling temperature (0-8°C) and humidity (50-98% relative humidity) to achieve a balance between weight preservation and flavor concentration, avoiding complete vacuum sealing while preventing excessive drying

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite packaging structures combining different materials with specific permeability characteristics to control gas and moisture exchange, achieving both weight preservation and flavor development simultaneously

Inventive Principle:
Principle #40Composite materials

2Loss of time

If accelerated maturation using mold Thamnidium elegans is applied, then maturation time is reduced to 12-48 hours, but the taste and tenderness do not satisfy demanding meat connoisseurs

Engineering Contradiction:
Improvematuration timeVSAvoidtaste quality
Core Design Contradiction:
Loss of timeVSObject-generated harmful factors

Solution Approach 1:

The patent optimizes temperature (0-8°C) and humidity (50-98% relative humidity) parameters to extend maturation time to 21-100 days, allowing thorough enzymatic breakdown of muscle fibers for superior tenderness and flavor development that accelerated methods cannot achieve

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent maintains continuous controlled maturation conditions over an extended period, allowing progressive and complete enzymatic action on muscle tissues, resulting in superior tenderness and flavor compared to interrupted or accelerated processes

Inventive Principle:
Principle #20Continuity of useful action

3Loss of substance

If traditional wet-aging in vacuum bags is used, then meat weight is preserved during ripening, but the aroma development is limited compared to dry-aging

Engineering Contradiction:
Improvemeat weightVSAvoidaroma concentration
Core Design Contradiction:
Loss of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent adjusts humidity levels (50-98% relative humidity) and temperature (0-8°C) to control the rate of water loss, achieving a balance where sufficient weight is preserved while enough moisture evaporates to concentrate aromatic compounds and develop flavor

Inventive Principle:
Principle #35Parameter changes

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 method produces tender and flavorful meat with a pleasant, intense taste, retaining the meat's natural characteristics, allowing it to be processed like fresh meat, with a low salt content and no curing substances, thus being healthier and more appealing to consumers.

Implementation Method 1

Liberated, protein-splitting enzymes, e.g. the cathepsins and calpains, in the second phase, cause the muscle fiber structures (myofibrils) to dissolve

Methodology Applied
Scientific EffectEnzymatic decomposition: Enzyme

Implementation Method 2

the use of microorganisms like Penicillium nalgiovense, Penicillium chysogenum, Penicillium gladioli, Penicillium camemberti, and Thamnidium elegans during meat maturation

Methodology Applied
Scientific EffectMicrobial decomposition: Decomposition (biological)

Implementation Method 3

The carbohydrate glycogen in the muscles is broken down into lactic acid (lactate) and energy, the ATP, is obtained

Methodology Applied
Scientific EffectFermentation: Fermentation

Implementation Method 4

The metabolism now takes place under anaerobic conditions

Methodology Applied
Scientific EffectAnaerobic metabolism: Anaerobic Digestion

Implementation Method 5

Dry-aging has the disadvantage that the meat loses weight due to cold evaporation of the water in the meat

Methodology Applied
Scientific EffectEvaporation: Evaporation
