Solution Overview

Problem

Puffed egg products, such as hot air-dried scrambled eggs, often exhibit poor restorability when rehydrated with hot water due to insufficient puffing, and there is a lack of understanding regarding the type of processed eggs that influence puffing and texture stability.

Innovation Solution

A processed egg with specific physical properties, including a viscosity slope of 20 cP/min or more measured using a rapid visco-analyzer (RVA), and a peak viscosity of 120 cP or more, which enhances puffability and restorability, along with a method for identifying suitable eggs by mixing with water and measuring viscosity changes.
