46
Q

usual processing of vegetable oils involves degumming and/or steam refining, adsorptive bleaching, hydrogenation, and deodorization

A

refining

47
Q

is accomplished by the use of adsorptive bentonite clays for edible
oils, and alternatively by chemical reactions for nonedible ones

A

Bleaching

48
Q

the conversion of various unsaturated radicals of fatty glycerides into more highly or completely saturated glycerides by the addition of hydrogen in the presence of a catalyst

A

Hydrogenation or hardening

49
Q

A

Hydrogenation or hardening

51
Q

removes most of the odor-causing compounds and also destroys many of the color-producing pigments present

A

deodorization

52
Q

is accomplished by blowing superheated steam through the
