Layered Sushi Composition with Sauce and Powder for Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sushi compositions lack differentiation in ingredients, leading to similar types of sushi, and struggle with preservation and nutritional value, particularly in meeting consumer demands for reduced calories and enhanced nutrient content.
Innovation Solution
A sushi composition featuring a protein-filled sushi layer covered with a sushi mixture containing konjac rice, turmeric, cumin, and Boehmeria nivea extract, topped with a sodium alginate and calcium chloride sauce layer, and a freeze-dried powder layer, which includes ingredients like fish roe, to enhance taste, texture, and preservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sushi ingredients are used, then traditional sushi preparation is simple, but the sushi lacks nutritional differentiation and has limited preservation
Solution Approach 1:
The sushi composition is divided into distinct functional layers: a sushi rice layer, a protein filling layer, a sauce layer, and a powder layer. Each layer serves specific purposes - the rice layer provides base structure and vinegar-based preservation, the protein layer adds nutrients, the sauce layer enhances flavor and preservation, and the powder layer provides additional nutrients and texture. This segmentation allows each component to be optimized independently for its specific function.
Solution Approach 2:
The patent combines multiple ingredients with different functional properties to create a composite sushi composition. The rice mixture includes konjac rice (low-calorie filler) combined with traditional sushi rice. The sauce layer combines sodium alginate, calcium chloride, vinegar, and various seasonings. The powder layer uses freeze-dried ingredients. This composite approach achieves enhanced preservation, nutrition, and flavor while managing complexity through functional integration.
2Ease of operation
If raw food ingredients are used on sushi rice, then the sushi has fresh taste, but the preservation of sushi rice is degraded
Solution Approach 1:
The sauce layer acts as an intermediary between the protein ingredients and the sushi rice. It contains vinegar (preservative), sodium alginate, and calcium chloride that form a protective barrier. This intermediary layer protects the rice from direct contact with raw ingredients that would accelerate spoilage, while still allowing flavor transfer and maintaining the freshness of protein components through controlled interaction.
Solution Approach 2:
The patent changes the physical and chemical parameters of ingredients through processing. Protein ingredients are subjected to quick freezing at -55 to -45°C followed by freeze-drying at 30 to 40°C for 40 to 48 hours, transforming them into stable powder forms. This parameter change (from raw to freeze-dried) extends preservation duration while maintaining taste quality through the retention of volatile compounds and nutritional components.
3Quantity of substance
If traditional sushi ingredients are used, then the preparation method is simple, but the sushi lacks nutrient diversity and has higher calorie content
Solution Approach 1:
Each layer in the sushi composition performs multiple functions. The rice layer not only provides structure but also includes konjac rice for calorie reduction and fiber addition. The protein layer provides primary nutrition. The sauce layer simultaneously provides flavor, preservation (vinegar), and texture (alginate-calcium chloride gel). The powder layer adds nutrients, flavor, and texture. This multi-functionality achieves nutrient diversity without proportionally increasing complexity, as each component serves several purposes.
Solution Approach 2:
Different regions of the sushi composition have specialized qualities optimized for specific functions. The rice layer has higher carbohydrate and fiber content (from konjac). The protein layer has concentrated protein. The sauce layer has higher moisture, vinegar, and seasoning concentration. The powder layer has concentrated flavor and nutrient particles. This local quality differentiation achieves overall nutrient diversity while keeping each layer's composition relatively simple and focused.

AI summary
The present invention relates to a sushi composition, and more specifically, to a sushi composition which includes a sushi layer, a sauce layer formed on an upper surface of the sushi layer, and a powder layer formed on a lower surface of the sushi layer, wherein the sushi layer consists of a filling made of a protein component and a sushi mixture covering the filling. The sushi composition has excellent taste and texture, contains abundant nutrients, and exhibits excellent preservation by applying various ingredients in the form of a sauce or powder.
