Solution Overview
Problem
Existing culinary practices face challenges in ensuring that prepared dishes meet diner expectations due to variations in ingredient quality, cooking skills, and personal taste preferences, leading to subjective experiences.
Innovation Solution
A method involving odor sensing and diffusing technologies to generate flavor signature deltas, which identify missing olfactory compounds in a dish, allowing for personalized odor mixtures to be emitted and ingredient suggestions to be provided, thereby enhancing the dining experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dish is prepared according to a recipe by a less skilled cook or with lower quality ingredients, then the preparation process remains simple and followable, but the dish fails to meet diner expectations in terms of taste and smell
Solution Approach 1:
An olfactory analysis system acts as an intermediary between the cook and the dish quality outcome. The system includes: (1) an olfactory sensor that captures odor compounds from the prepared dish, (2) a processor that compares the captured odor profile against a reference profile from a canonical version, and (3) a feedback mechanism that provides real-time guidance to the cook. This intermediary system enables less skilled cooks to achieve reliable dish quality by providing objective, data-driven feedback without requiring advanced culinary expertise
Solution Approach 2:
The patent replaces subjective human sensory evaluation (mechanical/tactile cooking skills) with an automated olfactory analysis system. Instead of relying on a cook's subjective judgment of smell and taste, the system uses: (1) gas chromatography-mass spectrometry (GC-MS) or similar olfactory sensors to objectively measure odor compounds, (2) computational algorithms to compare odor profiles and identify deviations, and (3) automated feedback delivery through display or audio interfaces. This substitution transforms subjective culinary art into an objective, measurable, and controllable process
2Adaptability or versatility
If ingredient substitutions are made to accommodate allergies or dietary constraints, then the dish becomes more adaptable to individual needs, but the olfactory characteristics may not meet original expectations
Solution Approach 1:
The system implements continuous feedback loops that enable real-time adjustment of ingredient substitutions. The process involves: (1) capturing the odor profile of the dish with substituted ingredients, (2) comparing it against the reference profile to identify specific olfactory deficiencies, (3) providing feedback recommendations for additional ingredients or adjustments, and (4) re-measuring to verify improvement. This feedback mechanism allows the system to dynamically optimize substitutions while maintaining olfactory characteristics, bridging the gap between dietary accommodation and sensory expectations
Solution Approach 2:
The system enables dynamic parameter changes in ingredient composition while maintaining target olfactory characteristics. When substitutions are made for dietary reasons, the system: (1) identifies which odor compounds are missing or reduced due to substitution, (2) calculates required adjustments in other ingredients to compensate for the olfactory gap, and (3) provides specific quantitative guidance on additional ingredients or cooking parameter adjustments. This approach transforms static recipe ingredients into dynamic, adjustable parameters that can be optimized for both dietary needs and sensory outcomes
3Ease of manufacture
If a cook uses lower quality ingredients due to monetary constraints or availability, then the cost and accessibility improve, but the odor compounds and overall quality deteriorate
Solution Approach 1:
The system enables self-service quality optimization where the cook independently identifies and corrects quality deficiencies without external expertise. The automated olfactory analysis system: (1) provides the cook with objective data about which odor compounds are missing or insufficient, (2) recommends specific, affordable ingredient substitutions or additions to compensate, and (3) allows the cook to make real-time adjustments based on feedback. This self-service approach empowers cooks to achieve high-quality results using accessible ingredients by providing them with the knowledge and tools previously available only to expert chefs

Data Source
AI summary
Techniques are disclosed for providing suggestions based on a flavor signature delta measured between samples prepared according to a recipe. An application obtains a flavor signature for a canonical sample prepared according to the recipe and a flavor signature for a sample subsequently prepared according to the recipe. The application generates a flavor signature delta from the flavor signatures of the samples. The flavor signature delta indicates a difference in the measure of each of the olfactory compounds in the samples. The application identifies one or more ingredients, each ingredient identified from at least one of the olfactory compounds present in the flavor signature delta. The application then generates one or more suggestions for preparing a sample based on the identified ingredients.
