Cheese Ripening Pressure Control for Shape Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cheese ripening methods result in significant shape deformations, particularly in low-fat, low-salt, and high-moisture cheeses, due to flow-induced deformation, which is not adequately addressed by existing technologies, and these deformations lead to cutting losses and inconsistent cheese dimensions.
Innovation Solution
A method combining natural and foil ripening with continuous pressure applied to the top and bottom surfaces of the cheese during the foil ripening stage, along with an optional pre-shaping step in a mould, to control and maintain the cheese's shape, reducing height variations and surface deformations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If natural ripening is used, then cheese develops traditional flavors and a rind, but significant shape deformations occur due to flow-induced deformation
Solution Approach 1:
The ripening process is divided into two distinct stages: natural ripening (for flavor and rind development) followed by foil ripening (for shape control). This segmentation allows each stage to optimize for its specific function without compromising the other.
Solution Approach 2:
The cheese is pre-shaped in a mould during the natural ripening stage to establish initial dimensional control before transitioning to foil ripening, where the foil packaging maintains the shape throughout the remaining ripening period.
2Adaptability or versatility
If low-fat, low-salt, and high-moisture cheese composition is used, then health requirements are met, but flow-induced deformation increases due to reduced flow resistance
Solution Approach 1:
The foil packaging acts as an intermediary element that provides external structural support to the cheese during ripening. This mediator compensates for the cheese's inherent lack of flow resistance due to its low-fat, low-salt, high-moisture composition.
Solution Approach 2:
The invention changes the physical state and constraints of the cheese by introducing foil packaging, which alters the boundary conditions during ripening. This parameter change enables shape control in cheese compositions that would otherwise be prone to deformation.
3Shape
If foil ripening is used, then shape control is improved and cutting losses are reduced, but moisture loss and rind formation are prevented
Solution Approach 1:
The invention applies foil packaging only for part of the total ripening period (after initial natural ripening), rather than throughout the entire process. This partial application allows the cheese to develop rind and moisture characteristics during natural ripening while gaining shape control benefits during foil ripening.
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 approach significantly reduces shape deformations by up to 55% in height variations and minimizes cutting losses, achieving more consistent cheese dimensions and maintaining the attractive 'drying edge' of naturally ripened cheese.
Implementation Method 1
pressure is continuously exerted on at least the top and bottom surface of said cheese during at least said foil ripening
Implementation Method 2
flow-induced deformation, which is particularly noticeable as the bulging out of the upright side walls of the lying cheese

AI summary
The invention pertains to a method for preparing a semi-hard or hard cheese, wherein a cheese of the semi-hard or hard type is formed, which, after brining, is subjected to ripening for a period of at least 4 weeks, said ripening comprising or consisting of foil ripening, and wherein pressure is continuously exerted on at least the top and bottom surface of said cheese during at least said foil ripening, preferably until said cheese is cooled.
