The invention discloses a green preparation method of acidolysis polysaccharide, which comprises the following steps: placing polysaccharide acid liquor in an induced electric field for acidolysis treatment to obtain acidolysis polysaccharide; the polysaccharide acid liquor comprises a polysaccharide-based material and inorganic acid. The induced electric field is used as an auxiliary means, the inorganic acid solution is used as a reaction medium, polysaccharide such as guar gum and chitosan is subjected to acidolysis modification, the polysaccharide preparation efficiency is higher than that of an existing polysaccharide acidolysis method by means of the Joule heating effect and the non-heating effect of the non-contact induced electric field, the molecular weight distribution interval of the obtained product is narrow, and the yield is high. Acidolysis is more thorough, polysaccharide molecules are more uniform and consistent, non-contact electric field acidolysis is safe and green, reaction conditions are
