The tenderness is poor, and the color is gray. Adding glycerin as a humectant can increase the water content under the condition of low water activity, thereby improving the tenderness. Adding 3% food grade glycerin can make the product water activity Aw<0.7, while the water content is controlled at 20%, the product tissue is soft, and the tenderness is improved.
