Mondo Knows Facts
Starch ratio determines whether cooked rice is fluffy or sticky
High amylose content yields firm separate grains while amylopectin causes stickiness
Rice starch consists of two glucose polymers: linear amylose and highly branched amylopectin. Long-grain rice varieties high in amylose retain their firm shape and separate easily when cooked. Conversely, short-grain glutinous rice consists almost entirely of amylopectin, which leaches out during cooking and gelatinises into a sticky cohesive mass.

Starch ratio determines whether cooked rice is fluffy or sticky: the short answers
- Where does this come from, and can I check it?
- High amylose content yields firm separate grains while amylopectin causes stickiness. The figure is taken from US Department of Agriculture, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.
- Is this really a food fact?
- Yes. It sits on the Food shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.
- What else can I read about it?
- The links under the fact point to a quiz, game, puzzle or calculator on the same subject, and the shelf below shows related facts. The wording here is original, and quoted phrases are marked as quotations.
