Ubuzima bwa Shelf ntarengwa bwibihumyo byumwami Impanda (Pleurotus eryngii)

Igihe cyo kubika ibihumyo byumwami bivana nuburyo bwo kubika hamwe nubuvuzi bwa nyuma. Hano hepfo hateganijwe protocole ishyigikiwe nubushakashatsi bwo kubungabunga ibiryo (IFT, 2022) nubuyobozi bwa USDA:

1. Gukonjesha bisanzwe

• Ubushyuhe: 0-2 ° C (± 0.5 ° C)
• Ubushuhe: 90-95% RH
• Gupakira: Imifuka ya polyethylene isobekeranye (5-8 umwobo / cm²)
• Ubuzima bwa Shelf:
  • Ibihumyo byose: Iminsi 12-14 (kugabanya ibiro <3%)
  • Ibihumyo bikatuye: Iminsi 7–9 (kubara mikorobe igenzurwa <10⁴ CFU / g)

Ikintu cy'ingenzi: Kwibanda kwa CO₂ 0002000 ppm kugirango wirinde guhumeka anaerobic.

2. Guhindura Ibikoresho byo mu kirere byahinduwe (MAP)

• Ibigize gaze: 5% O₂ + 10% CO₂ + 85% N₂
• Ubwoko bwa Filime: BOPP / PE firime yamurikiwe (OTR: 3000-4000 cm³ / m² · 24h · atm)
• Ubuzima bwa Shelf:
  • Iminsi 18-21 (nta kugaragara cyangwa kugaragara)
  • Igikorwa cya polifenol oxydease yagabanutseho 65%

Kwemeza: Ibizamini bya ATP bioluminescence byemeza gushya (RLU <800).

3. Gukuramo Vacuum + Gukonjesha

• Kubanziriza: Kugabanya temp yibanze kuri 4 ° C muminota 30
• Gukonja: IQF kuri -35 ° C → Ububiko kuri -18 ° C.
• Ubuzima bwa Shelf:
  • Amezi 10–12 (kugumana imyenda> 80%)
  • Nta gutakaza intungamubiri zikomeye (protein ≥92%, polysaccharide ≥88%)

Kugenzura ubuziranenge: Guhumeka (95 ° C / 2 min) mbere yo gukonjesha bibuza kwijimye.

4. Ikoreshwa rya tekinoroji yo kurya

• Amashanyarazi: 1.5% chitosan + 0.2% nano-SiO₂
• Inyungu:
  • Gutinda gufungura capa iminsi 5-7
  • Kugabanya igipimo cyo guhumeka 40%
  • Ikomeza gushikama (≥12 N imbaraga zo gutobora)
