AB  - Homogalacturonan (HG)-type pectin has been considered suitable for the formation 
      of hydrogel, but it is unknown whether the less side chain will limit the 
      properties of hydrogel. The current study successfully obtained low methoxyl 
      HG-type hawthorn pectin (LMHP) from hawthorn by sequential hot water extraction 
      and alkaline de-esterification. The proportion of HG domain, the proportion of 
      rhamnogalacturonan-I (RG-I) domain, molecular weight, and particle size of LMHP 
      were 81.13 %, 4.04 %, 348.43 kDa, and 1386.92 nm, respectively. Compared with 
      commercial citrus pectin (CP), LMHP was more suitable for the preparation of 
      hydrogel. The hydrogel with the densest network structure and relatively stable 
      performance in digestion simulation environment can be obtained as the 
      concentration of LMHP increases to 2.5 %, which is lower than the consumption of 
      commercial citrus pectin. Overall, these findings highlight the potential of 
      hawthorn pectin as a novel hydrogel raw material.
