How long is the shelf life of Yibin Lizhuang white cake and how long can it be preserved? ? Thank you for your help.

The shelf life of Lizhuang white cake in Yibin is generally **20 days * *. This traditional pastry is made of glutinous rice as the main material, supplemented by sugar and yam, and refined through more than ten traditional processes. Because the shelf life of glutinous rice can only be maintained within 20 days after adding sugar, it will deteriorate after more than 20 days, so the shelf life is 20 days. When buying and eating such cakes, we must pay attention to eating them within the shelf life, so as not to affect health and food quality.
