Currently, the number of people interested in nutritional supplements is increasing. In addition to the familiar forms of nutritional products in water and powder form, gel products are also a potential nutritional supplement line. The gel product is packaged in small packages, which is convenient to use anytime, anywhere and easy to control the dosage used. Besides, with a diverse structure from crispy to soft and many flavors and shapes, the product attracts many users, especially children. Gel foods have also been recommended by the American and European Society of Clinical Nutrition for people with swallowing problems who cannot use liquid and solid foods.
