Pulasitiki ndi chinthu chopangidwa kapena chopangidwa mwaluso chomwe chimakhala cholimba, chopepuka, komanso chosinthika.

Katundu ameneyu amalola kuti apange zinthu zosiyanasiyana, kuphatikiza zida zamankhwala, zida zamagalimoto, ndi zinthu zapakhomo monga zotengera zosungira zakudya, zotengera zakumwa, ndi mbale zina.

Komabe, mwina mungadabwe ngati mungathe kuyika tizilombo tating'onoting'ono tophikira chakudya, kutenthetsa zakumwa zomwe mumazikonda, kapena kutenthetsanso zotsalira.

Nkhaniyi ikufotokoza ngati mungathe kupanga mayikirowevu bwinobwino.

Mitundu ya pulasitiki

Pulasitiki ndi chinthu chopangidwa ndi maunyolo ataliatali a ma polima, omwe amakhala ndi mayunitsi zikwi zingapo obwerezabwereza otchedwa monomers ().

Ngakhale amapangidwa kuchokera ku mafuta ndi gasi wachilengedwe, mapulasitiki amathanso kupangidwa kuchokera kuzinthu zongowonjezwdwa monga zamkati zamatabwa ndi zopangira thonje ().

Pansi pazinthu zambiri zamapulasitiki, mupeza kansalu kobwezerezedwanso kokhala ndi nambala - nambala yazidziwitso ya utomoni - kuyambira 1 mpaka 7. Chiwerengerocho chimakuwuzani mtundu wa pulasitiki wopangidwa ().

Mitundu isanu ndi iwiri ya pulasitiki ndi zopangidwa kuchokera kwa iwo ndi (, 3):

1. Polyethylene terephthalate (PET kapena PETE): mabotolo akumwa soda, batala wa chiponde ndi mitsuko ya mayonesi, ndi zotengera zamafuta zophika
2. Mkulu osalimba polyethylene (HDPE): Zodzikongoletsera komanso zotengera sopo m'manja, zikho za mkaka, zotengera mafuta, ndi zidebe zopangira mapuloteni
3. Polyvinyl mankhwala enaake (PVC): mapaipi amaikira mipope, zingwe zamagetsi, zotchinga shawa, machubu azachipatala, ndi zinthu zopangidwa ndi zikopa
4. Low kachulukidwe polyethylene (LDPE): matumba apulasitiki, finyani mabotolo, ndi kulongedza chakudya
5. Polypropylene (PP): zisoti za mabotolo, zotengera za yogurt, zotengera zosungira zakudya, makapisozi a khofi osakwatiwa, matumba a ana, ndi mabotolo ogwedezeka
6. Polystyrene kapena Styrofoam (PS): kulongedza mtedza ndi zidebe zotayira, mbale, ndi makapu otayika
7. Zina: Mulinso polycarbonate, polylactide, acrylic, acrylonitrile butadiene, styrene, fiberglass, ndi nayiloni

Mapulasitiki ena amakhala ndi zowonjezera kuti akwaniritse zofunikira za zomwe zatsirizidwa (3).

Zowonjezera izi ndizopaka utoto, zolimbitsa, komanso zolimbitsa.

Pulasitiki amapangidwa makamaka kuchokera ku mafuta ndi gasi. Pali mitundu ingapo ya pulasitiki yomwe imakhala ndi mapulogalamu osiyanasiyana.

Kodi ndizotetezeka kupulasitiki yama microwave?

Chodetsa nkhawa chachikulu ndi pulasitiki yama microwave ndikuti imatha kuyambitsa zowonjezera - zina zomwe ndizovulaza - kulowa muzakudya ndi zakumwa zanu.

Mankhwala oyambira ndi bisphenol A (BPA) ndi gulu la mankhwala otchedwa phthalates, onse omwe amagwiritsidwa ntchito kukulitsa kusinthasintha komanso kulimba kwa pulasitiki.

Mankhwalawa - makamaka BPA - amasokoneza mahomoni amthupi lanu ndipo amalumikizidwa ndi kunenepa kwambiri, matenda ashuga, komanso kuvulaza ubereki (,,,).

BPA imapezeka makamaka m'mapulasitiki a polycarbonate (PC) (nambala 7), omwe akhala akugwiritsidwa ntchito kuyambira zaka za 1960 kupanga zotengera zosungira chakudya, magalasi akumwa, ndi mabotolo a ana ().

BPA yochokera m'mapulasitikiwa imatha kulowa muzakudya ndi zakumwa pakapita nthawi, komanso nthawi yomwe pulasitiki imawonekera kutentha, monga nthawi yomwe imakhala ndi microwave (,,).

Komabe, lero, ena opanga zakudya, kukonza, ndikugulitsa zinthu asinthanitsa pulasitiki ya PC ndi pulasitiki yopanda BPA ngati PP.

Food and Drug Administration (FDA) imaletsanso kugwiritsa ntchito zinthu zopangidwa ndi BPA ponyamula mkaka wa ana, makapu osokonekera, ndi mabotolo a ana ().

Komabe, kafukufuku wasonyeza kuti ngakhale mapulasitiki opanda BPA amatha kutulutsa mankhwala ena osokoneza bongo monga ma phthalates, kapena njira zina za BPA monga bisphenol S ndi F (BPS ndi BPF), muzakudya zomwe zimayikidwa ma microwaved (,,,).

Chifukwa chake, ndibwino kuti mupewe pulasitiki yama microwave, pokhapokha - malinga ndi a FDA - chidebechi chimadziwika kuti ndichotetezedwa kuti mugwiritse ntchito mayikirowevu ().

Pulasitiki ya microwave imatha kutulutsa mankhwala owopsa monga BPA komanso magawo azakudya ndi zakumwa zanu. Chifukwa chake, muyenera kupewa pulasitiki yama microwave, pokhapokha italembedwa kuti mugwiritse ntchito.

Njira zina zochepetsera kukhudzana kwanu ndi BPA ndi ma phthalates

Ngakhale microwave pulasitiki imathandizira kutulutsa kwa BPA ndi phthalates, si njira yokhayo yomwe mankhwalawa amatha kutha kukhala chakudya kapena zakumwa zanu.

Zina zomwe zingakulitse kutayika kwa mankhwala ndi monga (,):

• kuyika zakudya muzotengera za pulasitiki zomwe zidakali zotentha
• kupukuta zotengera zogwiritsira ntchito zopangira zinthu, monga ubweya wachitsulo, zomwe zingayambitse kukanda
• kugwiritsa ntchito zotengera kwa nthawi yayitali
• kuvumbula zotengera kuzitsuka mobwerezabwereza pakapita nthawi

Monga mwalamulo, zotengera zapulasitiki zomwe zaphwanyika, kulumidwa, kapena kuwonetsa kuvala, ziyenera kusinthidwa ndi zotengera zapulasitiki zopanda BPA zatsopano kapena zotengera zopangidwa ndi galasi.

Masiku ano, zida zambiri zosungira chakudya zimapangidwa kuchokera ku PP yopanda BPA.

Mutha kuzindikira zotengera zopangidwa ndi PP poyang'ana pansi pa sitampu ya PP kapena chikwangwani chokonzanso chomwe chili ndi nambala 5 pakati.

Kupaka chakudya pulasitiki ngati pulasitiki wokutira wokhalanso amathanso kukhala ndi BPA ndi phthalates ().

Mwakutero, ngati mukufuna kuphimba chakudya chanu mu microwave, gwiritsani ntchito sera, pepala, kapena chopukutira pepala.

Makontena apulasitiki omwe akanda, owonongeka, kapena atavala mopitirira muyeso, amakhala pachiwopsezo chachikulu chotulutsa mankhwala.

Mfundo yofunika

Mapulasitiki ndi zinthu zopangidwa makamaka kuchokera ku mafuta kapena mafuta, ndipo zimagwiritsidwa ntchito mosiyanasiyana.

Ngakhale kusungira zakudya zambiri, kukonzekera, ndi kugulitsa zopangidwa kuchokera ku pulasitiki, kuzisungunula kumatha kufulumizitsa kutulutsidwa kwa mankhwala owopsa monga BPA ndi phthalates.

Chifukwa chake, pokhapokha ngati mankhwala apulasitiki akuwoneka kuti ndi ma microwave otetezeka, pewani kuyiyika pama microwave, ndikusintha zida zapulasitiki zomwe zawonongeka ndi zatsopano.
