**2.5 Other applications**

Pectin's application has spread to water treatment where it is used as a biosorbent to remove heavy metals [47] and in urinary excretion of toxic minerals such as lead, cadmium, strontium, or arsenic [56–58]. In cosmetics, it is used as a plasticizer, texturizer and adhesive [59], and in biomedical applications, where it is used as a biomaterial ink to fabricate patient-specific scaffolds when cross-linked with 3-glycidyloxypropyl trimethoxysilane (GPTMS) [60]. Some examples of drug products that contain pectin are presented in **Table 1**.
