What it is Filled
Hard candy is a confection with a predominantly amorphous, glassy matrix of sugars or sugar alcohols, produced by concentrating a syrup and cooling it to form a rigid, brittle solid.
In scope
- Sugar-based and sugar-free hard-candy matrices
- Plain, flavoured, coloured and filled variants with a hard-candy body or shell
- Moisture, glass transition, crystallisation and their effects on texture
- Cooking, forming and cooling history relevant to the finished candy
- Piece geometry, surface condition and packaging interactions
- Ingredient identity, intended consumption and product-specific suitability constraints
Out of scope
- Standalone chemical models for sugars, polyols, acids, colours and flavourings
- Chewy sweets, gummies, fudge and predominantly crystalline compressed sweets
- Detailed design and operation of confectionery manufacturing equipment
- Independent models of wrappers, containers and packaging materials
- Medical diagnosis, dietary treatment and therapeutic efficacy
- Retail business operations and brand ownership
Why it exists Filled
Enable an agent to recognise hard candy, assess its physical and edible condition, and determine suitable handling, storage and use.
Distinguishing features Filled
- The defining candy body or shell is rigid and fractures rather than stretching or compressing like a gummy or chewy sweet at its stated use temperature.
- The defining matrix is predominantly glassy rather than a compacted powder or an intentionally crystalline mass; appearance alone does not establish this distinction.
- A lollipop belongs here when its edible body meets the hard-candy tests; the stick describes presentation rather than a different confection matrix.
- A filled piece qualifies through its hard shell even when its centre is liquid, powdery or chewy; the shell and centre must be described separately.
- Sugar-free composition does not exclude a piece when its sweetener matrix has the defining hard-candy structure and behaviour.
What robots and AI may and may not do Filled
Must not
- Give small hard candies to young children who can choke on them.
- Hide sugar or sugar alcohol content that matters to people with diabetes or digestive conditions.

- Handle molten sugar syrup near people without burn protection.
Only with a human decision
- Supplying candy in schools or care homes.
May
- Make, package and label hard candy following food hygiene and labelling rules.
- Report ingredients, allergens and sugar alcohol content.
