Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Formulating beverages with high-quality plant proteins is challenging due to issues like sedimentation, phase separation, gelation, and flavor masking, while maintaining taste and mouthfeel.
Innovation Solution
A method involving a plant protein blend of legume, whole grain, and dairy or wheat proteins, combined with sweetening and stabilizing components, subjected to high temperature treatment and homogenization to create a ready-to-drink beverage with up to 10 grams of complete protein per 8 ounces, ensuring good mouthfeel and balanced flavor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If plant proteins are included in beverages, then nutritional quality is improved, but sedimentation and phase separation occur
Solution Approach 1:
The patent uses a composite protein system combining soy protein isolate (80-90%), pea protein isolate (5-15%), and rice protein isolate (5-15%). This multi-component protein composite prevents sedimentation and phase separation while maintaining high nutritional quality, resolving the contradiction between protein content and beverage stability.
Solution Approach 2:
The patent applies high temperature treatment (190-212°F for 15-30 minutes) to denature and coagulate proteins, transforming them from a soluble to an insoluble state. This parameter change stabilizes the protein structure, preventing subsequent sedimentation and phase separation, thus maintaining both high protein content and beverage stability.
2Quantity of substance
If plant proteins are included in beverages, then nutritional quality is improved, but gelation and discoloration occur
Solution Approach 1:
The patent controls pH (6.0-7.0) and temperature (190-212°F) during protein treatment to achieve optimal coagulation without excessive gelation. This parameter control maintains desirable beverage texture while preventing unwanted gel formation and discoloration, preserving both nutritional quality and sensory properties.
Solution Approach 2:
The patent uses different protein sources with complementary properties: soy protein provides high nutritional value, pea protein contributes to texture, and rice protein helps maintain color stability. This local quality differentiation within the protein blend prevents uniform gelation and discoloration while maintaining overall nutritional quality.
3Quantity of substance
If plant proteins are included in beverages, then nutritional quality is improved, but interactions with calcium/cations and pH stability issues occur
Solution Approach 1:
The patent maintains pH between 6.0-7.0 and uses high temperature treatment to denature proteins before they can interact adversely with calcium and cations. This parameter control prevents precipitation and instability caused by protein-cation interactions, maintaining both high protein content and pH stability.
Solution Approach 2:
The patent uses calcium phosphate as a mediator that binds excess calcium ions, preventing direct interactions between calcium and plant proteins that would cause instability. This intermediary substance allows high protein content while maintaining pH and cation stability.
4Quantity of substance
If plant proteins are included in beverages, then nutritional quality is improved, but temperature stability issues occur
Solution Approach 1:
The patent applies high temperature treatment (190-212°F for 15-30 minutes) to pre-denature and coagulate proteins, making them thermally stable. This preliminary thermal treatment prevents temperature-induced instability during storage and distribution, maintaining both high protein content and temperature stability.
5Quantity of substance
If plant proteins are included in beverages, then nutritional quality is improved, but flavor balance becomes difficult to achieve
Solution Approach 1:
The patent combines three plant protein sources (soy, pea, rice) with complementary flavor profiles. Soy provides umami, pea contributes earthy notes, and rice adds subtle sweetness. This composite approach balances the strong flavors of individual plant proteins, achieving desirable taste while maintaining high nutritional quality.
Solution Approach 2:
The patent uses calcium phosphate and other additives as intermediaries that mask unwanted plant protein flavors while allowing beneficial nutritional properties to remain. These intermediary substances improve flavor balance without reducing protein content or nutritional quality.

AI summary
Ready-to-drink beverages comprise a significant amount of complete protein per 8 fluid-ounce serving, the proteins derived from a plant protein blend comprising a legume protein, a whole grain protein, and a dairy or wheat protein. Other components added include a sweetening component, a flavor component, hydrocolloids, and optionally maltodextrin to produce a ready-to-drink beverage with no visible sedimentation and good taste and mouthfeel. The components are subjected to a high temperature treatment step, followed by a homogenizing step. Formulations provide for source of high quality, complete protein.
