Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current processes for producing aroma particles in the food and pharmaceutical industries face challenges in achieving stable storage, preventing premature release or decomposition, and protecting flavorants and odorants from oxidation, particularly due to their sensitivity to atmospheric oxygen.
Innovation Solution
A process involving spray drying of particles with mono- or polysaccharides and sugar alcohols as binders in a fluidized bed, where the binder concentration is between 10 to 30 vol%, effectively agglomerates particles, enhancing storage stability and protecting aroma substances from oxidation by forming a porous structure that prevents premature release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If particles are produced by spray drying without binders, then the production process is simple and fast, but the particles lack storage stability and the flavorants are exposed to oxidation
Solution Approach 1:
A binder solution containing mono- or polysaccharides with reducing groups is introduced as an intermediary substance that mediates between the spray-dried particles and atmospheric oxygen. The binder forms a protective coating on particle surfaces, preventing direct contact between flavorants and oxygen while maintaining particle flowability and preventing premature aroma release.
Solution Approach 2:
The binder solution creates a protective environment around the particles that acts as a barrier against atmospheric oxygen. The reducing groups in the binder (such as those in maltodextrin, glucose, or other carbohydrates) provide antioxidant protection, effectively creating a localized inert environment that prevents oxidation of flavorants during storage.
2Reliability
If particles are agglomerated with binders to improve storage stability, then storage stability improves, but the particles may become less flowable and more cohesive
Solution Approach 1:
The binder concentration is precisely controlled at 10-30 vol% in the spray solution, and the binder molecular weight and composition are optimized to achieve the right balance. These parameter changes ensure that sufficient binder is present to provide oxidation protection and storage stability, while avoiding excessive binder that would cause poor flowability and excessive cohesion.
Solution Approach 2:
The binder forms a porous protective coating on the particle surfaces rather than a dense impermeable layer. This porous structure allows the particles to maintain their flowability and prevent clogging while still providing adequate protection against oxidation. The porosity enables breathability and prevents the particles from becoming too cohesive.
3Object-affected harmful factors
If the binder concentration is increased to improve protection against oxidation, then oxidation protection improves, but the particle size distribution may be affected and dust formation increases
Solution Approach 1:
The binder concentration is optimized at 10-30 vol% rather than using high concentrations. This parameter optimization provides sufficient oxidation protection while avoiding excessive binder that would cause poor particle size distribution and increased dust formation. The reduced sugar content in the binder solution also helps prevent crystallization and maintains particle uniformity.
