1. Standard refrigeration

• Okpomọkụ: 0–2°C (± 0.5°C)
• iru mmiri: 90-95% RH
• Nkwakọ ngwaahịaAkpa polyethylene perforated (oghere 5-8 / cm²)
• Ndụ shelf:
  • Olu niile: 12-14 ụbọchị (oke ọnwụ <3%)
  • Iberibe mushrooms: 7-9 ụbọchị (ọnụọgụ microbial na-achịkwa <10⁴ CFU/g)

Isi ihe: CO₂ ntinye uche ≤2000 ppm iji gbochie iku ume anaerobic.

2. Nkwakọ ngwaahịa ikuku gbanwere (MAP)

• Ngwakọta gas: 5% O₂ + 10% CO₂ + 85% N₂
• Ụdị ihe nkiriIhe nkiri BOPP/PE laminated (OTR: 3000–4000 cm³/m²·24h·atm)
• Ndụ shelf:
  • 18-21 ụbọchị (enweghị anya aja aja ma ọ bụ sliminess)
  • Ọrụ Polyphenol oxidase belatara site na 65%

nkwado: Nnwale ATP bioluminescence na-akwado ịdị ọhụrụ (RLU <800).

3. Vacuum Precooling + kefriza

• Na-adị jụụ: Belata isi okpomọkụ ka ọ bụrụ 4°C n'ime nkeji 30
• Na-ajụ oyi: IQF na -35°C → Nchekwa na -18°C
• Ndụ shelf:
  • Ọnwa 10–12 (njide ederede> 80%)
  • Enweghị nnukwu ụkọ nri (protein ≥92%, polysaccharides ≥88%)

Njikwa ogo: Blanching (95 ° C / 2 min) tupu oyi na-egbochi enzymatic browning.
