Yini Iphepha Elikahle Lokudla? Izindinganiso, Izinto, Nokuphepha

Definition

Izi zephepha ezisemthethweni zokudla zenzelwe ngokukhethekile ukuvumela ukuthintana okuqondile noma okungaqondile nokudla. Ivikela ukungcoliswa ngokulandela izindinganiso eziqinile zok regulation, iqinisekisa ukuthi akukho zinto eziyingozi ezidluliselwa kokudla. Ukusetshenziswa okuvamile kufaka phakathi ukupakisha, ukuh bake, ukuwasha, kanye nezitsha ezilahlwayo.

标准

Izi zephepha ezisemthethweni zokudla kumele zihambisane nemithetho yasendaweni kanye nezamazwe omhlaba ukuze kuqinisekiswe ukuphepha:

1. United States (FDA):

   - Iphathiswa ngu-FDA CFR Title 21, Izigaba 176 (izithako ezingaqondile) kanye ne-177 (ama-polymers ezindaweni zokuxhumana nokudla).

   - Requires materials to be inert and non-migratory under intended use conditions (e.g., temperature, moisture).

   - Iqinisekisa ukuthi akukhona imibala, ama-inki, noma ama-adhesives abulalayo.

2. European Union (EU):

   - EC 1935/2004 eyaqha imathiriyali akufanele engathinti impilo noma aguqule ukwakheka kokudla.

   - Specific measures for plastics, coatings, and recycled content (e.g., EC 10/2011 for plastics).

   - Imithetho kazwelonke (isb., i-LFGB yaseJalimane) iphakamisa ukuhlolwa kokuphepha okwengeziwe.

3. Ezinye Izindinganiso:

   - **ISO 22000:** Ikwesịrị ịtụle usoro njikwa nchekwa nri.

   - **BRC Global Standard for Packaging:** Ensures hygiene, traceability, and compliance.

   - **JFC (Japan) na IS 15495 (India):** Zvikamu zvemuno zve zvinhu zvinobata chikafu.

Matériel

Iziqhamo zokudla zephepha zenziwe ngezinto eziphephile, ezilawulwayo, ngokuvamile zinezelwa ezikhethekile:

1. Izinto eziyisisekelo:  

   - **Virgin Wood Pulp:** Ekhululekile ngokucacile; igwema izinto ezingcolile ezitholakala kumafibha aphindwe kabili.

   - **Bamboo or Sugarcane Bagasse:** Sustainable alternatives for items like plates or containers.

2. Coatings/Treatments:  

   - **PLA (Polylactic Acid):** Biodegradable coating for grease/oil resistance.

   - **Ukukhanya Kwe-Food-Grade Wax noma iSilicone:** Isetshenziswa ephepheni le-parchment lokubhaka elingabambi.

   - **Clay or PE (Polyethylene):** Ukuze kuvinjwe umswakama (qaphela: i-PE ayinakho ukuvikelwa kwemvelo).

3. Iintlobo eziqhelekileyo:

   - **Parchment Paper:** Silicone-coated, oven-safe.

   - **Wax Paper:** Iphakheji yokudla ye-paraffin noma i-beeswax (ayifanele ukushisa okuphezulu).

   - **Butcher Paper:** Uncoated, used for meat/food wrapping.

4. Recycled Content:  

   - Zivume kuphela uma kuhlanzekile futhi kuhlanzekile ukuze kukhishwe izinto ezingcolile (kulawulwa ngaphansi kwemigomo ye-FDA/EC).

Ukuphepha Izinto Zokucabangela

Ikey factors ensuring food-grade paper safety include:

1. Kemikali Ukuphepha:

   - **Ukuhlolwa Kokuhamba:** Qinisekisa ukuthi akukho ukudluliselwa okubi kwezinto (isb., izinsimbi ezinzima, i-PFAS, i-BPA) ngaphansi kwezimo ezifana nokushisa.

   - **Restricted Substances:** Prohibits toxic inks, adhesives, or coatings (e.g., EU bans PFAS in food packaging by 2023).

2. Ukuphepha Komzimba:  

   - **Durability:** Ihlala ibamba ukuguguleka noma ukuwa uma imanzi (isb., amafutha ekhofi).

   - **Ukushisa Ukumelana:** Kubalulekile kumaphepha okubhaka (kuvumela izinga lokushisa elijwayelekile le-oveni).

3. Microbial Safety:  

   - **Non-Toxic Production:** Iindlela zigwema ukukhuthaza ukukhula kwamagciwane.

   - **Allergen Controls:** Iindawo zingadinga ukuhlukaniswa ukuze kugwenywe ukungcoliswa.

4. Ukuphila kahle:

   - **Compostability:** Ipaphe ezivunyelwe zokuphendula (isb., BPI, TÜV OK Compost) kumele ziqhume ngokuphepha.

   - **Biodegradability:** Izinto ezifana ne-PLA noma iphepha le-kraft elingenamaki ziya zihlala zishintsha ngokwemvelo.

Izicelo  

- **Direct Contact:** Sandwich wraps, baking sheets, candy liners.

- **Indirect Contact:** Ibhokisi zephakheji, amalebula.

- **Specialized Uses:** Iphakhe elingangeni, iziqukathi eziphephile ze-microwave.

**Isiphetho**  

Iziqhamo eziphephile zephepha zihlanganisa izinto ezilawulwayo, ukuhlolwa kokuphepha okuqinile, kanye nezindlela zokusebenza ukuze kuqinisekiswe ukuhambisana nezindinganiso zempilo. Izinto ezibalulekile okufanele zicatshangelwe zifaka phakathi ukungabi nezezimali, izimo zokusetshenziswa ezihlosiwe, kanye nokusimama. Ngaso sonke isikhathi qinisekisa izitifiketi (isb., FDA, EC) futhi ugweme ezinye izinketho ezingahambisani nezidingo zokuphepha kokudla.
