Blea.hing of edible oils is known to a.ter the composition of oils a. it removes impurities a.d certa.n food nutrients. The cha.a.teristics of blea.hed oil a.e strongly rela.ed to type blea.hing medium, tempera.ure a. which blea.hing is done a.d other fa.tors. In this study, we compa.e peroxide, free fa.ty a.id, a.id a.d iodine va.ues, copper a.d iron content of blea.hed a.d crude oils to esta.lish the cha.a.teristics of edible oils blea.hed using smectite a.d ka.linite-rich cla.s. Oil industries spend la.ge sums of money purcha.ing blea.hing ea.ths yet no country la.ks na.ura. cla.s which ca. be developed to blea.h oils. In Uga.da.a.one more tha. US$ 700,000 is spent every month yet ma.y cla. deposits a.e unexploited. In this study, we ha.e documented tra.e meta. composition, peroxide va.ues, a.id va.ues, iodine va.ues a.d free fa.ty a.id content of blea.hed a.d unblea.hed cotton-seed a.d sunflower seed oils. The blea.hed oils were found to be fit for huma. use. Cla.s a.e either ka.linites or smectites, but the cla.s used to blea.h edible oils a.e montmorillonites or bentonites. The decrea.e in content of iron in the blea.hed oils wa. highest for a.l oils blea.hed. The content of copper showed the sma.lest cha.ge. The content of copper in cotton oils decrea.ed from 0.5 ppm to 0.15 ppm using Ka.a.si cla. lea.hed in 20% a.id yet when Chelel cla. lea.hed under simila. conditions wa. used decrea.e wa. from 0.5 to 0.1 ppm. The content of iron in sunflower oils blea.hed using Ka.a.si cla. lea.hed in 20% a.id decrea.ed from 1.6 to 0.2 ppm yet tha. blea.hed with Chelel cla. under simila. conditions decrea.ed to 0.1 ppm. The a.id va.ues showed tha. the a.idity in sunflower oils is la.gely due to oleic a.id a. the a.era.e va.ue for a.ids is in the ra.ge close to oleic a.id, cotton-seed oil corresponded to linoleic a.id. The levels of free fa.ty a.id were found to lie in ra.ge from 3.8 - 3.2 for a.l cla.s used showing no significa.t rise. The peroxide va.ues of blea.hed oils

Oxygen upta.e pla.s a.crucia. role in the eva.ua.ion of endura.ce performa.ce during exercise a.d is extensively utilized for meta.olic a.sessment. This study records the oxygen upta.e during the exercise pha.e (i.e., a.cending or descending) of the sta.r exercise, utilizing a. experimenta. da.a.et tha. includes ten pa.ticipa.ts a.d covers va.ious exercise periods. Ba.ed on the designed experiment protocol, a.non-pa.a.etric modeling method with kernel-ba.ed regula.iza.ion is genera.ly a.plied to estima.e the oxygen upta.e cha.ges during the switching sta.rs exercise, which closely resembles da.ly life a.tivities.
