A consumer survey preceded by a pilot study consisting of
personal interviews was conducted in order to determine
consumer attitudes towards oxygen absorbers used in food
packages. The consumer survey questionnaires were given
out with food samples (pizza with ham filling and sliced
rye bread) packed both with and without an oxygen
absorber in three Helsinki area supermarkets. Three
hundred and fifty-two satisfactory responses were
returned, resulting in a response rate of 89%. Half of
the consumers received an information leaflet about
Overall, 72% of consumers accepted the use of oxygen
absorbers and 23 % could not decide. The acceptance was
higher among those who received the information leaflet -
76% vs. 67% in the no information group (p = 0.03).
However, the information given appeared to have no effect
on negative responses - in both groups, ca. 5% of
consumers did not accept oxygen absorbers.
Consumers who held a negative attitude towards food
packaging and long shelf-lives also expressed more
negative attitudes towards oxygen absorbers
(p < 0.001). Correspondingly, consumers accepting the
use of additives favoured the absorbers (p < 0.01).
Gender, age, education or other demographic factors were
not related to the attitudes towards oxygen absorbers.
The use of absorbers was accepted well in the sample
foods (pizza 62% and rye bread 57%) used in this study,
whereas only 29 % would accept them in fresh meat.
Respondents who used pizza and sliced rye bread were
frequently more in favour of absorbers. Forty per cent of
consumers were willing to pay at least 10 pennies (FIM
0.1) more for products with an oxygen absorber.
In voluntary comments the reduction in the amount of
additives used in food products was regarded as the
absorber s major advantage, whereas their harmful
substance and the waste produced were seen as the major
disadvantages. The main concerns were that the absorbers
would break up inside the package or they would fall into
the possession of children or pets.
