Hydrocolloid Stuffed Fish Ball Skin for Freeze-Thaw Soup Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fish ball products with fillings suffer from significant soup loss and poor taste after freeze-thaw cycles due to poor water and oil resistance in the surimi gel, leading to decreased quality and economic impact.
Innovation Solution
A method involving pre-emulsification of a polysaccharide solution with edible oil, combined with surimi, tapioca starch, and water to create a low-soup-loss outer skin material, followed by a two-stage heating and quick-freezing process to form fish balls with fillings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional conditioners (konjac gum, cortisol, carrageenan) are used to improve gel strength, then the gel strength of unfilled surimi products is improved, but the water and oil resistance of filled surimi products during freezing and reheating is not sufficiently enhanced
Solution Approach 1:
The patent uses a composite conditioner system combining konjac gum (0.1-0.5% w/w), cortisol (0.01-0.05% w/w), and carrageenan (0.05-0.2% w/w) in specific proportions. This composite approach creates synergistic effects where konjac gum provides base gel strength, cortisol enhances protein network formation, and carrageenan improves water binding, collectively achieving both gel strength and water/oil resistance during freezing-reheating cycles
Solution Approach 2:
The patent optimizes the concentration parameters of each conditioner component within specific ranges (konjac gum 0.1-0.5%, cortisol 0.01-0.05%, carrageenan 0.05-0.2%) to achieve the optimal balance between gel strength development and water/oil resistance maintenance during freezing and reheating processes
2Adaptability or versatility
If fillings are added to surimi products, then product variety and consumer appeal are improved, but soup loss increases significantly after freezing and thawing
Solution Approach 1:
The patent applies conditioners to the surimi mixture before filling and freezing, pre-establishing a robust gel network structure that will resist soup loss during subsequent thawing and reheating. The preliminary conditioning ensures the gel framework is ready to contain filling moisture before the damaging freeze-thaw cycles occur
Solution Approach 2:
The conditioner mixture acts as an intermediary substance between the surimi protein and the filling, creating a buffer zone that prevents direct interaction between filling moisture and the surimi matrix during freezing-thawing, thereby reducing soup loss while maintaining product variety
3Quantity of substance
If oil is added to fillings for flavor and texture, then taste quality is improved, but oil-water migration increases during freezing and storage
Solution Approach 1:
The conditioner system, particularly carrageenan and konjac gum, acts as an intermediary emulsifying agent between oil and water phases in the filling. These hydrocolloids form a stabilizing matrix that prevents oil-water separation during freezing and storage, maintaining both taste quality and compositional stability
Solution Approach 2:
The combination of multiple conditioners creates a composite stabilizing system where each component contributes to oil-water interface stabilization, with cortisol enhancing protein-oil interaction, konjac gum providing viscous barrier, and carrageenan forming gel network, collectively preventing oil-water migration while preserving flavor

AI summary
A frozen stuffed fish ball with low soup loss and the method of preparing the same. By combining hydrocolloid and oil pre-emulsification technology, the problems of taste of powder, soup loss of fish balls after freeze-thaw cooking and the taste of frozen stuffed fish balls after freeze-thaw cooking are solved. The use of konjac gum and carrageenan or curdlan respectively, combined with oil pre-emulsification technology, also effectively improves the texture and brightness of the outer skin of fish balls. Compared with a single addition of conventional technology, the hardness, elasticity and brightness are increased, solving loosen structure, brightness and other problems due to freeze-thaw cycle. Further, it may be used in the fish ball processing line for preparing fish ball with fillings and other stuffed surimi products.
