The hydrolysis of sucrose in aqueous solutions upon heating is a well-established chemical fact of basic chemistry that requires no formal citation.
The claim states that sucrose undergoes hydrolysis in boiling water within a measurable timeframe. This is a basic, well-known chemical property of sucrose (inversion of sugar by heat in water) that is part of foundational chemistry education and everyday observation. Therefore, it is classified as common knowledge under STEP 0, requiring no citation, and the indices lists are left empty.
