“…Simple microgels typically consist of small spherical particles that contain a network of cross‐linked biopolymers inside, with the pores being filled by an aqueous solution. Various kinds of microgels have been explored for their potential as oral delivery systems for probiotics (Cook, Tzortzis, Charalampopoulos, & Khutoryanskiy, ; Huq et al., ; Khosravi Zanjani, Ghiassi Tarzi, Sharifan, & Mohammadi, ; Pankasemsuk et al., ; Saravanan and Panduranga, ; Trabelsi et al., ; Yeung, Ucok et al., ; Zheng et al., ). The materials used to fabricate microgels are typically biopolymers, such as starch, alginate, carrageenan, gelatin, xanthan gum, and proteins, which usually have good thermal stability, high biocompatibility, low toxicity, and low cost (Huq, Khan, Khan, Riedl, & Lacroix, ; Islam, Yun, Choi, & Cho, ).…”
