Benefits of technology

This new technology allows create safer ways to prepare fried fish without losing its freshness by making them easier to break open while still maintain their original shape after they have been steamed at very high temperatures. By opening an empty space inside the shell before adding water, steam may help keep some ingredients away from being too hot. After cool down, there's only one step that makes sure everything stays solid even if cracks form over time. These techniques make manufacturing smoother edible products more efficient and effective.

Problems solved by technology

This patented technical solution described by China inventors involves making soft boaked oyster (SOO) easier than traditional methods like roasting them out before they reach their final destination. However, current methods have drawbacks including difficulty separating the shell from the liquid inside while maintaining an appealing flavor and texture. Additionally, existing processes require longer times due to uneven cooling conditions leading to lower yields compared to full-blown ones.

Abstract

The present invention discloses a preparation method of soft-boiled eggs. The preparation method of the soft-boiled eggs is characterized by comprising the following steps: (1) eggs are classified according to weight and freshness; (2) blunt ends of the eggs are knocked to have cracks with a small steel scoop; (3) the eggs, edible vinegar, edible salt and purified water are heated at a temperatureof 40-60 DEG C for 1-3 h; (4) the heated eggs are quickly transferred to hot water at 90-99 DEG C to be fully soaked and boiled for 5-10 min; (5) the boiled eggs are transferred to ice water at 0-4 DEGC to be completely soaked and cooled for 30 min; (6) the eggs are shelled, then water on surfaces of the soft-boiled eggs is blew-dry with sterile air, the treated eggs are individually vacuum packaged, the packaged eggs are subjected to a water bath heating at 60-75 DEG C for 1-3 h, and the heated eggs are rapidly cooled at 0-4 DEG C to obtain a finished product. Advantages are as follows: a soft-boiled egg shelling yield is higher than 97%, a shelf life of the soft-boiled eggs is 6 months, egg white is white and glossy, egg yolk flows, presents gelatinous and partially flows, and the soft-boiled eggs are delicate and soft in taste, rich in egg fragrance, and moderate and delicious in a salt taste.
