Adulterate, sophisticate, load, weight and doctor mean to alter fraudulently especially for profit.
Adulterate, the usual and technical term, especially when used with reference to foodstuffs and drugs, implies either the admixture of ingredients of similar appearance to increase the bulk or of a harmful substance as a preservative or as a restorer or improver of appearance.
- adulterate maple syrup with beet-sugar syrup
- lime juice adulterated with five percent sulfuric acid, jellies with formaldehyde, peas with copper
In its extended use adulterate implies spuriousness or loss of purity; such implications come out strongly in unadulterated, which is the equivalent of pure and sheer in their hyperbolic senses.
- that book is unadulterated trash
In meaning sophisticate is essentially identical with adulterate but its use is restricted almost entirely to raw drug and essential oil trade.
- rose oil is sophisticated with geraniol
Load implies the admixture of something to add weight whether as an adulterant or in the normal course of manufacture.
- numerous adulterants have been used to load tea to increase its weight
- most kinds of paper are loaded in some way or other . . . . The process . . . was first practiced . . . to save pulp . . . but it was found that restricted quantities of loadings improved the paper
Weight is used interchangeably with load but is applied more especially to textiles.
- silk weighted with salts of tin
Doctor implies tampering sometimes by adulteration but more often by alterations or falsifications which give an illusion of genuineness, of superior quality, or of great value.
