Solution Overview

Problem

Traditional bubble tea products, such as tapioca balls, are not shelf-stable and deteriorate quickly in aqueous beverages, limiting their availability and compatibility with various beverage types, including sparkling drinks.

Innovation Solution

A dual-texture food composition comprising an outer layer of high G-type alginate or pectin and an inner layer of fruit juice or puree with a gum and insoluble calcium salt, which can be formed into stable bubble bits that maintain texture and stability during prolonged shelf storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional tapioca balls are used in bubble tea, then the product can be prepared fresh and served immediately, but the tapioca balls disintegrate quickly in aqueous beverage and are not shelf-stable

Engineering Contradiction:
Improveshelf-stabilityVSAvoidstructural integrity
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The bubble bit is constructed as a composite structure with an outer layer made from aqueous alginate solution and an inner layer made from fruit juice, gum, and insoluble calcium salt. This composite material structure provides both shelf-stability and structural integrity, resolving the contradiction between reliability and compositional stability.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The invention changes the chemical composition parameters of the bubble bit by using specific ratios of high G-type alginate to high M-type alginate (greater than 1), and controlling the concentration of gums (xanthan and/or konjac) at 0.01-1.5% (w/w). These parameter changes enable the bubble bit to maintain structural integrity while achieving shelf-stability.

Principle #35Parameter changes

2Reliability

If tapioca balls are made shelf-stable, then they can be stored and used in various beverages, but traditional formulations lose their satisfactory mouth-feel and texture

Engineering Contradiction:
Improveshelf-stabilityVSAvoidmouth-feel
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The bubble bit employs local quality differentiation with two distinct layers: the outer alginate layer provides structural stability for shelf-storage, while the inner layer containing fruit juice, gum, and insoluble calcium salt maintains satisfactory mouth-feel and texture. Each layer has optimized local properties that address different requirements.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention optimizes parameters including the ratio of high G-type to high M-type alginate (greater than 1), gum concentration (0.01-1.5% w/w), and the inclusion of insoluble calcium salt (0-2.0% w/w). These parameter changes enable the product to achieve both shelf-stability and satisfactory mouth-feel simultaneously.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If traditional bubble tea is prepared fresh, then it maintains optimal texture and stability, but it limits availability and cannot be used in sparkling beverages

Engineering Contradiction:
Improvebeverage compatibilityVSAvoidstorage duration
Core Design Contradiction:
Adaptability or versatilityVSDuration of action of stationary object

Solution Approach 1:

The composite structure with outer alginate layer and inner fruit juice-gum-calcium salt layer creates a bubble bit that is compatible with various beverages including sparkling drinks. The stable composition allows extended storage duration while maintaining versatility across different beverage types.

Inventive Principle:
Principle #40Composite materials

AI summary

The principles of the present invention provide compositions and methods for making dual-texture bubble bits that are shelf-stable in ready-to-drink beverages, and provide a bursting and chewy mouth-feel sensation. The method may include combining an outer layer of high "G" alginate with high "M" alginate or pectin, and an inner layer including fruit puree/juice with gum and insoluble calcium salt to simulate the organoleptic properties of fresh bubble tea starch balls.
