Potasiyumu dikarboksilatini yo nyongeramusaruro ya mbere idakoresha imiti yica udukoko yemejwe n'Umuryango w'Ubumwe bw'u Burayi. Ni uruvange rwa potasiyumu dicarboxylate na aside formike binyuze mu mugozi wa hydrogen hagati y'ibinyampeke. Ikoreshwa cyane mu ngurube z'ingore n'ingurube zikura zirangije. Ibisubizo by'igerageza ryo kugaburira byagaragaje ko kongera potasiyumu dicarboxylate mu mirire y'ingurube bishobora kongera ibiro by'ingurube no kugabanya umubare w'impfu ziterwa n'ubwandu bwa bagiteri. Kongera potasiyumu dicarboxylate mu biryo by'inka bishobora no kongera umusaruro w'amata y'inka.

Muri ubu bushakashatsi, ibipimo bitandukanye byapotasiyumu dicarboxylatebyongewe mu biryo bya poroteyine nkeya za Penaeus vannamei, kugira ngo haboneke umuti utera imbere udakoresha imiti yica udukoko mu buryo bwiza kandi butangiza ibidukikije.

Ibikoresho n'uburyo

1.1 Ifunguro ry'igerageza

Ibisubizo by'igerageza ry'ibiryo n'ibisubizo by'isesengura ry'imiti bigaragara mu mbonerahamwe ya 1. Hari amatsinda atatu y'ibiryo mu igerageza, kandi ibikubiye muri potasiyumu dicarboxylate ni 0%, 0.8% na 1.5% uko bikurikirana.

1.2 Isambaza zo kugerageza

Uburemere bw'umubiri bwa mbere bwa Penaeus vannamei bwari (57.0 ± 3.3) mg) C. Igerageza ryagabanyijwemo amatsinda atatu, buri tsinda rigasubiramo gatatu.

1.3 Ibikoresho byo kugaburira

Ubuhinzi bw'amafi bwakorewe mu tuzu tw'urushundura dufite imiterere ya 0.8 mx 0.8 mx 0.8 m. Utuzu twose tw'urushundura twashyizwe mu kidendezi cy'isima gitemba (uburebure bwa metero 1.2, umurambararo wa metero 16.0).

Igerageza rya 1.4 ryo kugaburira potassium formate

Amatsinda atatu y'indyo (0%, 0.8% na 1.5% potasiyumu dicarboxylate) yashyizwe kuri buri tsinda mu buryo butunguranye nyuma yo gupima ibice 30 / agasanduku. Ingano y'ibiryo yari 15% by'uburemere bw'umubiri bwa mbere kuva ku munsi wa 1 kugeza ku munsi wa 10, 25% kuva ku munsi wa 11 kugeza ku munsi wa 30, na 35% kuva ku munsi wa 31 kugeza ku munsi wa 40. Igerageza ryamaze iminsi 40. Ubushyuhe bw'amazi ni 22.0-26.44 ℃ naho umunyu ni 15. Nyuma y'iminsi 40, uburemere bw'umubiri bwapimwe kandi bubarwa, ndetse n'uburemere.

Ibisubizo 2.2

Dukurikije igerageza ry’ubwinshi bw’amafi yo mu bwoko bwa “stocking”, ubwinshi bwiza bw’amafi yo mu bwoko bwa “stocking” bwari amafi 30 ku gisanduku. Igipimo cyo kubaho cy’itsinda ryagenzuwe cyari (92.2 ± 1.6)%, naho igipimo cyo kubaho cy’itsinda rya potassium diformate rya 0.8% cyari 100%; Ariko, igipimo cyo kubaho cya Penaeus vannamei cyaragabanutse kigera kuri (86.7 ± 5.4)%, ubwo urwego rwo kongeramo rwazamukaga kigera kuri 1.5%. Igipimo cy’ibiryo nacyo cyagaragaje icyerekezo kimwe.

Ibiganiro 3

Muri ubu bushakashatsi, kongeramo potasiyumu diformate bishobora kongera umusaruro wa buri munsi n'umubare w'ubuzima bwa Penaeus vannamei. Igitekerezo kimwe cyatanzwe ubwo hongerwagamo potasiyumu dicarboxylate mu biryo by'ingurube. Byemejwe ko kongeramo 0.8% bya potasiyumu diformate mu biryo by'isambaza bya Penaeus vannamei byagize ingaruka nziza zo gukura. Roth et al. (1996) batanze inama yo kongeramo ingurube mu biryo byiza, byari 1.8% mu biryo by'ibanze, 1.2% mu biryo byo konsa na 0.6% mu biryo byo gukura no kurangiza ingurube.

Impamvu potasiyumu dicarboxylate ishobora gutuma habaho gukura ni uko potasiyumu dicarboxylate ishobora kugera mu mara afite alkaline nke binyuze mu kugaburira igifu cy’inyamaswa mu buryo bwuzuye, hanyuma igahinduka aside formike na formate, ikagaragaza ingaruka zikomeye za bagiteri na bagiteri, bigatuma amara y’inyamaswa asa n’aho ari "adafite ubusembwa", bityo ikagaragaza ingaruka zo gukura.
