Stainless Steel Prep
All prep surfaces are 304 food-grade stainless steel sanitized hourly with hospital-grade, food-contact-safe quat solutions.
Digital Probe Logging
Every batch of fried chicken is probed digitally. We mandate a core internal temperature of >74°C (165°F) before plating.
Zero Moisture Sog
Unidirectional paperboard exhaust chimneys expel steam, preventing humid bacteria incubation during transit.
1. Cloud Kitchen Hygiene Protocol (Sholinganallur Hub)
Because friedstack operates a pure cloud facility with zero customer foot-traffic, our kitchen maintains clinical cleanroom cleanliness standards:
- Mandatory Gear: Kitchen crew wear hair restraints, beard nets, disposable nitrile gloves (changed every 45 mins), and sanitized non-slip footwear.
- Two-Stage Hand Sanitization: Sensor-activated soap scrubs followed by 70% isopropanol hand misting before entering the cook line.
- Raw vs. Cooked Segregation: Distinct color-coded prep stations and tongs prevent cross-contamination between raw marinated poultry and cooked crisp items.
- Air Filtration & Positive Pressure: Multi-stage HVAC filtration cycling fresh air to maintain optimal kitchen ambient temperatures.
- Daily Deep-Clean Cycle: Nightly 90-minute sanitation teardown of all fryers, warming chutes, and exhaust hoods at 1:30 AM close.
- FSSAI Registered: Operating under rigorous Food Safety and Standards Authority of India (FSSAI) guidelines.
2. 48-Hour Buttermilk Brine & Cold-Chain Integrity
Our signature crunch and juicy texture are produced by our 48-hour buttermilk and botanical spice brine. Protecting this process requires unwavering cold-chain rigor:
Fresh chicken is sourced daily from certified farms complying with antibiotic-residue-free standards. It undergoes rigorous inspection upon delivery docket check-in before entering the brine vault.
3. Oil Quality & Thermal Frying Chemistry
Old oil ruins both flavor and digestive wellness. friedstack employs strict scientific cooking oil monitoring:
| Safety Parameter | friedstack Operating Standard | Industry Baseline |
|---|---|---|
| Total Polar Materials (TPM) | Discarded at ≤ 18% TPM | FSSAI limit ≤ 25% |
| Daily Test Frequency | Digital optical sensor tested 3x daily | Visual inspection only |
| Cooking Temperature | Calibrated 175°C – 180°C precision fryers | Variable unmonitored pans |
| Internal Core Temperature | Probe verified > 74°C (165°F) minimum | Spot checks |
4. Zero-Sog™ Packaging & Tamper Seals
Packaging is the final frontier of food safety. Most takeout packaging creates a greenhouse chamber where heat and trapped steam cause bacterial proliferation and ruin texture.
- 100% Virgin Food-Grade Paperboard: Certified BPA-free, PFAS-free, and unbleached. No recycled toxic post-consumer paper touches your hot food.
- Moisture Chimneys: Die-cut chimney vents release steam upward while angled heat baffles reflect radiant heat downward, keeping your food hot and dry.
- Indestructible Tamper Seals: Every dispatch bag is sealed with a proprietary tamper-evident security tape. If torn, cut, or peeled, an unmistakable void pattern reveals interference.
5. Contactless Rider Handover Station
Our Sholinganallur facility features a dedicated contactless rider dispatch vestibule separated from the active cooking line:
- Riders from Swiggy and Zomato never enter the food preparation area.
- Packages rest in heated dispatch chutes (holding at 65°C) until the exact verified rider arrives.
- Rider thermal delivery bags are inspected for clean insulated liners prior to bag handover.
