Ngaba iincasa zendalo zingcono ngenene kunencasa ezenziweyo

Ukusuka kwimboniselo yemboniselo, ivumba lisetyenziselwa ukuqwalasela i-flavour yevumba elibi lezinto, umthombo walo wahlulahlulwe ngamacandelo amabini: enye "incasa yendalo", ukusuka kwizityalo, izilwanyana, izinto ezincinci zisebenzisa "indlela yomzimba" ukukhupha izinto zevumba;Enye yi "synthetic fragrance", eyenziwe ngezinye "distillate" kunye ne-asidi, i-alkali, ityuwa kunye nezinye iikhemikhali ezifunyenwe kumacandelo amaminerali afana ne-petroleum kunye namalahle ngonyango kunye nokucubungula.Kwiminyaka yakutshanje, iincasa zendalo bezifunwa kakhulu kwaye amaxabiso anyukile, kodwa ngaba iincasa zendalo zingcono ngenene kunencasa ezenziweyo?

Iziqholo zendalo zahlulwe ngokweziqholo zezilwanyana kunye neziqholo zezityalo: iziqholo zendalo zezilwanyana zizintlobo ezine: musk, civet, castoreum kunye neambergris;Isityalo esinevumba elimnandi ngumxube wendalo okhutshwe kwiintyatyambo, amagqabi, amasebe, iziqu, iziqhamo, njl., zezityalo ezinevumba elimnandi.Iziqholo ze-Synthetic zine-semi-synthetic spices kunye ne-synthetic synthetic spices: ukusetyenziswa kwecandelo lendalo emva kokusabela kweekhemikhali ukuguqula ulwakhiwo lweziqholo ezibizwa ngokuba yi-semi-synthetic spices, ukusetyenziswa kwezinto ezisisiseko zeekhemikhali ekrwada zokwenziwa ezibizwa ngokuba ziziqholo ezipheleleyo zokwenziwa.Ngokohlelo lwamaqela asebenzayo, iziqhumiso ezenziwe nge-synthetic zinokwahlulwa zibe ngamavumba e-ether (i-diphenyl ether, i-anisole, njl.), iziqhumiso ze-aldehyde-ketone (i-musketone, i-cyclopentadecanone, njl.), iziqhumiso ze-lactone (isoamyl acetate, i-amyl butyrate, njl. ), iziqhumiso zotywala (utywala obunamafutha, utywala obunevumba elimnandi, utywala be-terpenoid, njl.), njl.

Iziqholo zakwangoko zinokulungiswa kuphela ngeencasa zendalo, emva kokuvela kweencasa zokwenziwa, iziqholo zinokuphantse zilungele ukulungiselela iintlobo ngeentlobo zeencasa ukuze zihlangabezane neemfuno zazo zonke iinkalo zobomi.Kubasebenzi beshishini kunye nabathengi, eyona nto ixhalabisayo kukuzinza kunye nokhuseleko lweziqholo.Iincasa zendalo azikhuselekanga, kwaye iincasa zokwenziwa azikhuselekanga.Ukuzinza kwencasa kubonakaliswa ikakhulu kwiinkalo ezimbini: okokuqala, ukuzinza kwabo kwiphunga okanye incasa;Okwesibini, ukuzinza kwezinto ezibonakalayo kunye neekhemikhali ngokwazo okanye kwimveliso;Ukhuseleko lubhekiselele ekubeni kukho ityhefu yomlomo, ubutyhefu bolusu, ukucaphuka kolusu kunye namehlo, nokuba ukudibana kolusu kuya kuba nokwalana, nokuba kukho ityhefu ye-photosensitivity kunye ne-photosensitization yolusu.

Ngokubhekiselele kwiziqholo, iziqholo zendalo zingumxube onzima, ochatshazelwa yimiba efana nemvelaphi kunye nemozulu, engazinzanga ngokulula ekubunjweni kunye nevumba, kwaye ihlala iqulethe iindidi ezahlukeneyo.Ukubunjwa kwevumba kuyinkimbinkimbi kakhulu, kwaye kunye nenqanaba langoku lekhemistri kunye ne-biotechnology, kunzima ukufezekisa uhlalutyo oluchanekileyo ngokupheleleyo kunye nokuqonda amacandelo ayo avumba, kwaye impembelelo emzimbeni womntu akulula ukuyiqonda.Eminye yale mingcipheko ayaziwa kuthi;Ukubunjwa kweziqholo zokwenziwa kucacile, iimvavanyo ezifanelekileyo zebhayoloji zinokwenziwa, ukusetyenziswa okukhuselekileyo kunokufezekiswa, kwaye ivumba lizinzile, kwaye ivumba lemveliso eyongeziweyo linokuzinza, nto leyo esizisa lula ekusebenziseni.

Ngokuphathelele izinyibilikisi ezishiyekileyo, iziqholo ezenziweyo ziyafana neziqholo zendalo.Iincasa zendalo nazo zifuna i-solvents kwinkqubo yokukhupha.Kwinkqubo yokudibanisa, i-solvent inokulawulwa kwindawo ekhuselekileyo ngokukhetha i-solvent kunye nokususwa.

Uninzi lweencasa zendalo kunye neencasa zibiza kakhulu kuneencasa zokwenziwa kunye neencasa, kodwa oku akuhambelani ngokuthe ngqo nokhuseleko, kwaye ezinye iincasa zokwenziwa zibiza kakhulu kunencasa yendalo.Abantu bacinga ukuba indalo ingcono, ngamanye amaxesha ngenxa yokuba amavumba endalo enza abantu babe mnandi ngakumbi, kwaye ezinye izithako zomkhondo kwiincasa zendalo zinokuzisa umahluko ofihlakeleyo kumava.Ayisiyonto yendalo ilungile, i-synthetic ayilungile, ukuba nje ukusetyenziswa ngaphakathi kwendawo yemimiselo kunye nemigangatho ikhuselekile, kwaye ukuthetha ngokwesayensi, iziqholo zokwenziwa ziyakwazi ukulawulwa, zikhuselekile ngakumbi, kwinqanaba langoku, zilungele ukusetyenziswa koluntu.
