## Mission

CareEZ is a public-good social enterprise. Its mission is to ensure that clinical nutrition standards and AI safety tools for older adults with dysphagia remain accessible and not commercially extracted. It explicitly does not accept equity that transfers clinical IP or pricing control outside the social enterprise structure.

## Programmes

### 1. Care-food Products (照護食 / 護食)

SeniorDeli is CareEZ's care-food product line — texture-modified food and beverages for older adults and care facilities. Products are:

- **IDDSI-compliant**: aligned with the International Dysphagia Diet Standardisation Initiative (8 levels, 0–7)
- **HKCSS 護食標準-aligned**: the Hong Kong-specific clinical benchmark for care food
- **T/SATA 094-credentialed**: Chinese group standard for dysphagia diet
- Distributed across 200+ partner care facilities in Hong Kong
- Available in powder and portion formats for facility-scale preparation

### 2. Clinical AI Tools

Point-of-care AI for swallowing safety and IDDSI compliance. Includes:

- IDDSI texture classification (food and liquid)
- Thickener dosage calculation
- Voice-based aspiration risk screening
- Clinical Q&A on dysphagia / care food standards
- Recipe modification to target IDDSI levels

Accessible via browser at https://demo.careez.org and REST API (see endpoints below).

## Clinical Standards Context

- **IDDSI** (International Dysphagia Diet Standardisation Initiative): Global framework classifying food texture and liquid thickness across 8 levels (0 = thin liquid → 7 = regular). Endorsed by WHO, ASPEN, BDA, SLP professional bodies worldwide.
- **HKCSS 護食標準**: Hong Kong Council of Social Service Care Food Working Group standard — the HK-specific benchmark. Aligns with IDDSI and adds culturally appropriate texture criteria.
- **T/SATA 094**: Chinese group standard for dysphagia diet products. SeniorDeli holds this credential.
- **Dysphagia**: Difficulty or discomfort swallowing. Affects ~28–42K residential care home (RCHE) residents and an estimated 640K daily frontline care workers in Hong Kong making meal-safety decisions.
