Enkambisweni yokufuya ama-shrimp, abalimi abaningi babhekana nobunzima obulandelayo: intshiseko yokondla ama-shrimp iyancipha, ukukhula kuyehla, futhi ngisho nomkhuba wokuthi "ukudla wedwa akuhlali isikhathi eside" uyenzeka.

Lokhu akugcini nje ngokuthinta imininingwane ye-shrimp, kodwa futhi kunciphisa ngqo ukusebenza kahle kokuzalanisa. Izimbangela zale nkinga ziyinkimbinkimbi futhi ziyahlukahluka, ikakhulukazi ezihlobene nekhwalithi yezithombo ze-shrimp, indawo enamanzi, ukuphathwa kwezilwane zasemanzini, impilo yamathumbu, kanye nokutheleleka ngezifo.

Izizathu eziyinhloko zokudla kancane nokukhula kwe-shrimp

1. Ukucaciswa okungalingani kwezinto ezibangela ukuthosa kwe-shrimp: Ezinye izithosa ze-shrimp ngokwazo zinobukhulu obuhlukene, futhi amazinga azo okukhula kamuva ayahlukahluka ngokwemvelo. Umthombo ongaziwa: Izithosa ze-shrimp ezivela emapulazini ezithosa angakahleleki zingase zibe nokuwohloka kwezakhi zofuzo noma zithwale amagciwane, okungaholela kalula ekumisweni kokukhula noma ngisho nasezifweni ezigabeni zakamuva.

2. Izici zekhwalithi yamanzi: Ukugcwala ngokweqile kwe-ammonia nitrogen kanye ne-nitrite emanzini, noma amanani aphezulu e-pH esikhathi eside, kungalimaza izicubu ze-gill kanye nezitho zokugaya ukudla ze-shrimp, kubangele ukusabela kokucindezeleka, futhi kuvimbele ukudla nokukhula.

3. Uma kunezinhlobo eziningi kakhulu zezilwane zemvelo kanye nezilwane ezidla izinhlanzi (njengezinhlayiya ze-branchiopods nama-copepods) echibini ziningi kakhulu, izimfanzi zizodla kakhulu lezi zinhlobo zemvelo, okuholela ekunciphiseni kokudla okwenziwe ngokwenziwa futhi kudale umbono wokuthi ukudla kuhamba kancane. Ngokuhamba kwesikhathi, ukukhula kungase kwehle ngenxa yokuntuleka kokudla okunomsoco.

4. Ukuphathwa okungalungile kanye nobuningi obukhulu bezitokisi: ukweqa umthamo wokuthwala ichibi kungabangela kalula ukusabela kokucindezeleka kanye nokuncintisana okungalingani kokudla. Izinga lamanzi angajulile: Umzimba wamanzi unomswakama obuthakathaka kanye nokuqina, kanye nokushintshashintsha okukhulu kwezinga lokushisa lamanzi kanye nokucindezeleka okuvamile kwezinkabi

Ukushintshana kwamanzi okwanele: Ukuqongelela kwemfucuza ye-metabolic emanzini kungaholela kalula ekuwohlokeni kwekhwalithi yamanzi, okuthinta ukudla nokukhula kwezinhlanzi.

Inani lokudla elingafanele: Ngokuvamile kunconywa ukondla ama-shrimp ngesilinganiso sansuku zonke esingu-6% kuya ku-8% wesisindo somzimba wawo (okungashintshwa kalula ngokuya ngokushisa kwamanzi, umoya-mpilo oncibilikisiwe, kanye nezimo zokudla). Ukondla okunganele kungaholela ekuvinjelweni kokukhula, kuyilapho ukondla ngokweqile kungangcolisa kalula i-substrate futhi kwandise umthwalo esibindini nakuma-pancreas.

5. Izici zesifo: Izifo zamagciwane (njengokutheleleka kwe-Vibrio) kanye nezifo zamagciwane (njenge-vitiligo syndrome) zingalimaza ngqo isibindi, amanyikwe, namathumbu e-shrimp, okuholela ekunciphiseni kokugaya kanye namandla okumunca, okuvame ukubonakala njengokunciphisa ukudla noma ukuyeka ukudla.
Ukulimala kwamathumbu kanye nesisu esingenalutho ku-jejunum kuyizimbangela ezivamile zokulahlekelwa ukudla kwe-shrimp kanye nokumiswa kokukhula.

Kanjanii-potassium diformateukuthuthukisa inkinga yokondla kancane kanye nokuntuleka kokukhula kwenyama kuma-shrimp

I-Potassium diformateiyilungiselelo le-organic acid elisetshenziswa kabanzi, eliqukethe ikakhulukazi i-formic acid kanyei-potassium diformateInezici zokuphepha okuluhlaza, ukuvikela amagciwane kanye namathumbu, ukukhuthaza ukukhula okuphumelelayo, futhi ayinazo izinsalela noma ukumelana nemithi, okuhlangabezana nezidingo zokufuywa kwezinhlanzi okuluhlaza.
Ngokuphathelene nezinkinga zokudla nokukhula kwezinhlanzi zaseNingizimu Melika, indlela esebenza ngayo ibonakala kakhulu kulezi zici ezilandelayo:

1. Ukuthuthukisa impilo yamathumbu.I-Potassium diformateingalawula inani le-pH yamathumbu, ivimbele ukwanda kwamagciwane ayingozi (njengamagciwane avamile abangela izifo njenge-Vibrio), futhi ikhuthaze ukwanda kwamagciwane anenzuzo njenge-lactic acid bacteria, igcine ibhalansi ye-microbiota yamathumbu futhi inciphise ngempumelelo ukwenzeka kwe-enteritis.

2. Thuthukisa umsebenzi wama-enzyme okugaya ukudla futhi ukhuthaze ukusetshenziswa kwamaprotheni ngokuthuthukisa ukungena kwamathumbu.I-Potassium diformateingathuthukisa umsebenzi wama-protease kanye namanye ama-enzyme okugaya ukudla, ikhuthaze ukuqhekeka nokumuncwa kwamaprotheni ekudleni, ngaleyo ndlela ikhulise izinga lokuguqulwa kokudla, inciphise ukusebenza kahle kokudla (isilinganiso sokudla), futhi inciphise ukungcola kwezakhamzimba.

3. Ukuthuthuka okuphawulekayo ekusebenzeni kokukhula kanye nezinga lokusinda. Izifundo zezazi zaseShayina uHe Suxu et al. (2006) zibonise ukuthi ukwengeza u-0.8%i-potassium diformateUkwenyuka kokudla kwezinhlanzi ezimhlophe zaseNingizimu Melika kungandisa isisindo esiphelele sezinhlanzi ngo-20.6%, ukukhuphuka kwesisindo nsuku zonke ngo-26%, kanye nesilinganiso sokusinda ngo-7.8%. Imiphumela yocwaningo ikhombisa ukuthi i-potassium formate ingathuthukisa ngempumelelo isimo sokudla kwezinhlanzi futhi ikhuthaze ukukhula komuntu ngamunye.

4. Ukudla okuzinzile kanye nokusabela okuncishisiwe kokucindezeleka.I-Potassium diformatekungathuthukisa indawo yamathumbu kanye nesimo sempilo iyonke yezinhlanzi, kuzisize zibhekane kangcono nezingcindezi zemvelo ezifana nokushintshashintsha kwekhwalithi yamanzi, ukucindezeleka kobuningi, kanye nokucindezeleka kwezifo, ngaleyo ndlela zilondoloze ukuziphatha okuzinzile kokudla futhi zinciphise ukuzonda ukudla okubangelwa ukucindezeleka.

Iziphakamiso

Uma abalimi behlangabezana nezimo lapho ukudla kwama-shrimp kuhamba kancane futhi kungakhulisi inyama, kufanele baqale bahlole ikhwalithi yezithombo zama-shrimp, izinkomba zekhwalithi yamanzi, ubuningi bamasheya, nokuthi ngabe zikhona yini izifo, bese belungisa uhlelo lokuphatha ngokufanele ngokusekelwe esimweni sangempela emlonyeni wechibi.

Ngesikhathi esifanayo, i-potassium formate yesayensi ingasetshenziswa ekudleni (sicela ubheke imiyalelo yomkhiqizo ukuze uthole umthamo othize, bese ulungisa ngokuguquguqukayo ngokwezincazelo ze-shrimp kanye nendawo yokuzalanisa). Ukusetshenziswa kwesikhathi eside nokunengqondo kungasiza ekugcineni impilo yamathumbu, kuthuthukise ukusetshenziswa kokudla, futhi ekugcineni kufeze umgomo "wokukhulisa i-shrimp enkulu nenhle".

Ukugcina amathumbu e-shrimp kubalulekile ukuze kudliwe kahle, kukhule inyama ngokushesha, kuthuthukiswe imininingwane, futhi kukhule inzuzo.
