Bokosi lazakudya, monga dzina limatanthawuzira, limagwiritsidwa ntchito kuyika mabokosi a chakudya, limatha kugawidwa malinga ndi zinthu monga: bokosi lamatabwa, bokosi lamapepala, bokosi lansalu, bokosi lachikopa, bokosi lachitsulo, bokosi lamalata, etc. matabwa, mapepala ndi zinthu zina zosakaniza pamodzi. Kulongedza bokosi ntchito: kuonetsetsa chitetezo cha chakudya mu mayendedwe, kusintha kalasi ya mankhwala, etc. Cholinga cha bokosi chakudya ma CD ndi makamaka kuteteza chakudya ku chikoka cha zinthu mankhwala thupi ndi tizilombo tating'onoting'ono zinthu, kuonetsetsa kuti zikuchokera zakudya ndi chibadidwe khalidwe la chakudya sizisintha, kuti ateteze thanzi la ogula. Kuphatikiza apo, chakudya chophatikizika chimapereka zinthu zambiri zabwino zoyendera, kusungirako, kugulitsa ndikugwiritsa ntchito, kwinaku akulimbikitsa malonda. Kulongedza bwino chakudya kungathe kutalikitsa moyo wake wosunga ndi shelufu, ndi kuchepetsa kwambiri chizoloŵezi cha kuwonongeka kwa chakudya. Zomwe zimakhudza ubwino wa chakudya ndi: - kuwala; Chachiwiri ndi kutentha; Chachitatu ndi mpweya; Zinayi ndi chinyezi; Chachisanu, ma microbes. Kuchokera pakupanga chakudya, kugulitsa ndi kugwiritsa ntchito mfundo zitatu, cholinga cha bokosi lazakudya: - ndikuletsa kuwonongeka, kuonetsetsa kuti zabwino; Awiri ndi kuteteza tizilombo toyambitsa matenda ndi fumbi kuipitsa; Chachitatu, kulinganiza ndi kufulumizitsa kupanga chakudya; Chachinayi, imathandizira pamayendedwe ndi kuzungulira; Chachisanu, onjezerani mtengo wamtengo wapatali wa chakudya. Zakudya ma CD bokosi malinga ndi zikuchokera zopangira, ogaŵikana polyethylene, polypropylene, polystyrene, polyvinyl kolorayidi ndi mitundu ina, polyethylene, polypropylene ndi pulasitiki otetezeka, angagwiritsidwe ntchito muli chakudya. Mabokosi apulasitiki a thovu otayidwa ndi nthawi imodzi yokhala ndi thovu polystyrene akamwe zoziziritsa kukhosi bokosi, zopangira zazikulu ndi polystyrene ndi thovu wothandizila thobvu, polystyrene ndi styrene ma polima, kufika 65 digiri Celsius, padzakhala ena ufulu wa styrene ndi kusamuka kwa mtundu wa zinthu zoipa zotchedwa dioxins, kuvulaza thupi la munthu. Kuphatikiza apo, wowombeza ndi mtundu wazinthu zamankhwala zovulaza thupi la munthu. Mabokosi ena a zakudya omwe amaphwanya malamulo a dziko amatulutsa fungo losasangalatsa akadzazidwa ndi chakudya chotentha, chomwe ndi zinthu zapoizoni zomwe zimatulutsidwa ndi mabokosi apulasitiki otulutsa thovu. Zinthu izi zidzawononga dongosolo lapakati lamanjenje laumunthu ndikuwopseza kwambiri thanzi la anthu.
