Wet Aging Meat Packaging with Adsorptive Fat Layer Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dry aging of meat is time-consuming and expensive, while traditional wet aging results in significant weight loss and a metallic taste that consumers prefer to avoid, necessitating an improved method for tenderizing and flavoring meat.
Innovation Solution
A packaging method for wet aging that includes an adsorptive material and salt applied to the fat layer of the meat, with a piece of wood paper to enhance aroma and desiccation, sealed in a vacuum to minimize moisture loss and preserve flavor, reducing shrinkage and aging time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional wet aging is used to tenderize meat, then the aging time is reduced and cost is lowered, but the meat develops a metallic taste and significant weight loss occurs
Solution Approach 1:
The patent introduces an intermediary substance (charcoal or other adsorptive material) placed inside the vacuum package with the meat. This intermediary absorbs volatile compounds responsible for the metallic taste during the wet aging process, while allowing the meat to remain in contact with its own juices for tenderness development. The intermediary acts as a filter that selectively removes harmful volatiles without interfering with the beneficial proteolytic enzyme activity.
Solution Approach 2:
The patent modifies the chemical environment within the package by introducing adsorptive materials that change the composition of headspace gases and surface conditions. By altering the chemical parameters (absorbing specific volatile compounds), the meat develops different sensory properties - eliminating the metallic taste while preserving the tenderness benefits of wet aging.
2Object-generated harmful factors
If dry aging is used to improve flavor, then the meat develops desirable taste, but the aging time increases and weight loss reaches one third or more
Solution Approach 1:
The patent creates an inert or controlled atmosphere within the package by using vacuum sealing combined with adsorptive materials that absorb oxygen and other gases. This modified atmosphere allows the meat to develop flavor similar to dry aging without direct oxygen exposure, preventing excessive oxidation and moisture loss while still achieving desirable taste development through controlled enzymatic activity.
Solution Approach 2:
The adsorptive material serves as a mediator that controls the interaction between the meat and the package headspace. It selectively absorbs volatile compounds and gases, creating a controlled environment that mimics some benefits of dry aging (flavor development) while preventing the severe moisture loss associated with traditional dry aging methods.
3Loss of substance
If vacuum packaging is used for wet aging, then moisture loss is minimized, but the meat still develops unwanted volatile compounds and metallic taste
Solution Approach 1:
The patent places an intermediary adsorptive material inside the vacuum package that specifically targets and absorbs unwanted volatile compounds produced during wet aging. This intermediary coexists with the meat in the same sealed environment, continuously removing harmful volatiles from the headspace and surface atmosphere without interfering with moisture retention or the tenderizing process.
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
This method achieves lower shrinkage and weight loss compared to dry aging, while enhancing the flavor of the meat, resulting in a more desirable taste and reduced aging time, addressing consumer preferences for dry-aged flavor without the drawbacks of traditional wet aging.
Implementation Method 1
The adsorptive material is used to collect gases emitted from the cut of meat
Implementation Method 2
The salt acts as an aromatic, but also is used to pull moisture from the cut of meat
Implementation Method 3
vacuum packaging meat in a plastic material to seal the meat so that moisture cannot escape from within the package
