Beverage Precursor Block with Inclusions for Flavor Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beverage precursors, such as instant powders and granules, suffer from flavor loss, inconvenience in preparation, and instability due to oxidation and moisture absorption, especially when containing inclusions like leaves and fruits, which require separate addition and lack structural support.
Innovation Solution
A dried beverage precursor block comprising plant extract and insoluble inclusions, formed into a cohesive solid mass without external compression, using a water-soluble carrier to enhance strength and flavor retention, allowing for convenient preparation and improved inclusion retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If beverage precursors are produced as instant powders or granules through intensive processing, then they dissolve rapidly and completely, but volatile material is lost resulting in inferior flavour
Solution Approach 1:
The patent employs freeze-drying (lyophilization) which utilizes phase transition of water from liquid to solid (freezing) and then from solid to gas (sublimation) under vacuum conditions. This process preserves volatile aromatic compounds better than spray-drying while still producing a rapidly dissolving beverage precursor. The frozen structure creates a porous matrix that allows quick water penetration and dissolution.
Solution Approach 2:
The freeze-drying process creates a highly porous structure in the beverage precursor with interconnected voids and channels. This porous morphology provides large surface area for rapid water absorption and dissolution while maintaining the integrity of volatile compounds during processing. The porous structure also facilitates quick rehydration without requiring intensive mechanical processing.
2Productivity
If beverage precursors are distributed in heavy bulk containers, then distribution is efficient, but the free-flowing nature requires heavy containers and causes spillage and mess
Solution Approach 1:
The patent combines multiple beverage precursor units into a single cohesive tablet or compressed form. This merging approach eliminates the need for bulk containers while maintaining distribution efficiency. The compressed unit is self-contained, portable, and eliminates spillage issues associated with loose powders. Consumers can carry individual tablets without requiring heavy bulk packaging.
Solution Approach 2:
The beverage precursor is formed into a compact tablet or pellet with a cohesive structure that acts as its own protective shell. This solid form factor eliminates the need for external bulk containers while maintaining portability and preventing spillage. The compact form can be easily packaged in lightweight individual servings or small containers.
3Ease of operation
If beverage precursors are portioned by spoon or implement, then individual servings can be obtained, but wide fluctuation in strength and quality occurs and loss through spillage is frequent
Solution Approach 1:
The patent divides the beverage precursor into pre-portioned individual tablets or units, each containing a precise amount of active ingredients and inclusions. This segmentation ensures consistent dosing and beverage strength while eliminating the need for manual spooning. Each tablet is a self-contained, uniform portion that dissolves reliably to produce consistent beverage quality.
Solution Approach 2:
The beverage precursor is pre-portioned and pre-mixed during manufacturing with exact formulations of extracts, inclusions, and carriers. This preliminary action of precise formulation and compression eliminates variability introduced by manual portioning. Each tablet is prepared in advance with controlled composition, ensuring reliable and consistent beverage strength and quality.
4Ease of operation
If bulk containers are opened frequently to remove portions, then individual servings can be accessed, but remaining precursor deteriorates due to oxidation and moisture absorption
Solution Approach 1:
The beverage precursor is divided into individual sealed tablets or single-serving units. Each unit is hermetically sealed to prevent exposure to oxygen and moisture until use. This segmentation allows consumers to access one portion at a time while keeping remaining units protected, eliminating deterioration issues associated with bulk container exposure.
Solution Approach 2:
Each beverage precursor unit is enclosed in a protective barrier such as foil wrapping or sealed packaging that prevents oxidation and moisture absorption. This protective shell maintains flavour and aroma integrity during storage and only needs to be opened at the moment of use, preventing deterioration of remaining portions.
5Speed
If small powder particles are used, then dissolution is rapid, but large pieces of dried aromatic plant material cannot be included as they disintegrate during transit
Solution Approach 1:
The patent creates a composite structure where delicate dried plant inclusions (leaves, flowers, fruit pieces) are embedded within a supportive matrix of beverage extract and carrier material. This composite approach provides mechanical strength to protect fragile inclusions during handling and transit while maintaining rapid dissolution properties. The matrix acts as a protective scaffold that holds inclusions intact until contact with water.
Solution Approach 2:
The beverage precursor is compressed into a cohesive tablet or pellet form that encases and protects fragile inclusions within its structure. This solid matrix provides a protective shell around delicate plant materials, preventing disintegration during transit while allowing rapid water penetration and dissolution when activated. The compressed form maintains inclusion integrity without requiring them to be ground into fine particles.
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 blocks minimize portioning needs, retain flavor and aroma, and provide structural support for inclusions, resulting in a more stable and convenient beverage preparation process with enhanced sensory impact.
Implementation Method 1
comprising a water-soluble carrier, plant extract and at least one inclusion
Implementation Method 2
the small size of the powder particles or granules (typically of the order of a mm or less) makes it impractical to include large (or even whole) pieces of dried aromatic plant material along with the beverage precursor. This is because free-flowing powders provide little structural support to fragile inclusions such as dried leaves and fruits which thus disintegrate during transit.
Implementation Method 3
beverage precursor granules which remain in the container for several weeks may show a marked deterioration due to loss of flavour and aroma, production of bad flavours owing to oxidation processes and loss of flowability owing to moisture absorption.
