Solution Overview

Problem

Existing infant nutritional compositions fail to effectively promote the growth of beneficial Lactobacillus and Bifidobacterium bacteria, leading to sub-optimal gut microbiota development, particularly in infants born via C-section, preterm infants, and formula-fed infants, which can result in conditions such as diarrhea, atopic diseases, and allergies.

Innovation Solution

A nutritional composition comprising fructo-oligosaccharides and/or galactooligosaccharides combined with beta-casein, where at least 75% of the beta-casein has a proline at position 67 of the amino acid sequence, synergistically increases Lactobacillus levels and decreases pathogenic bacteria, thereby improving gut microbiota.

VSEngineering Contradiction Analysis

1Reliability

If conventional infant nutritional compositions are used, then basic nutritional needs are met, but beneficial Lactobacillus and Bifidobacterium bacteria are not effectively promoted, leading to sub-optimal gut microbiota development

Engineering Contradiction:
Improvegut microbiota developmentVSAvoidbeneficial bacteria growth
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies parameter changes by modifying the protein composition parameter - specifically using beta-casein with proline at position 67 instead of conventional proteins. This amino acid substitution creates a novel protein structure that synergistically enhances the growth of beneficial bacteria when combined with prebiotics, thereby improving gut microbiota development without compromising basic nutrition

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite materials by combining beta-casein (with specific proline-containing sequence) and prebiotics in a defined formulation. This composite nutritional composition creates a synergistic effect where the protein and prebiotics work together to selectively promote beneficial bacteria growth, addressing the limitation of conventional single-component nutritional formulations

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If formula feeding is used, then nutritional requirements are provided, but the microbiota becomes more diverse with higher numbers of pathogenic bacteria compared to breast-fed infants

Engineering Contradiction:
Improvenutritional contentVSAvoidpathogenic bacteria levels
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by creating a targeted nutritional environment that selectively promotes beneficial bacteria while suppressing pathogenic bacteria. The beta-casein with proline at position 67, when combined with prebiotics, creates a localized favorable condition for Lactobacillus and Bifidobacterium growth in the gut, without providing the same advantage to pathogenic species

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent converts the potential harm of formula feeding (which typically increases pathogenic bacteria) into a benefit by using a specially designed protein-prebiotic combination. This formulation transforms the nutritional provision function into a dual function that also actively suppresses pathogenic bacteria while promoting beneficial ones, thereby converting the harmful effect into a protective one

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

The present invention relates to nutritional compositions comprising non-digestible oligosaccharides and beta-casein comprising at least 75% by weight of a beta-casein variant having a proline at position 67 of the beta-casein amino acid sequence for use in improving gut microbiota of an infant or child, wherein improvement of gut microbiota encompasses increasing Lactobacillus levels. Advantageously, the composition further favors the increase of Bifidobacterium levels and inhibits the growth of opportunistic and/or pathogenic bacteria.
