Two locations (home and central locations) and two scales (number and box scales) were tested. One hundred and twelve subjects from low-income households measured four samples (two chocolate milks and two soups). Samples had higher scores in the home location than in the central location. In the central location consumers were more critical than in the home location test. If sensory acceptability discrimination is of interest, the central location test would be more adequate for low-income populations. Statistically both scales gave similar results; however, consumers found the number scale more familiar and easier to use.The adequate methodology to measure food acceptability among low-income population was researched.

For measuring sensory acceptability among low-income populations, we have come up with a simple number scale: consumers are instructed to score the sample from 1 to 10, this being a universal scoring system in many countries. If discrimination of sensory acceptability among samples is the objective of the test, central location would be more advisable than a home usage test.Understanding the phenomenon of income-related food preferences has received little attention in published research.
