Production of a video tape promoting safety knowledge of pasteurized beverages packed in hermetically sealed containers
Abstract:
This study was conducted to examine the production of a video presentation as the
media to provide knowledge about safer and healthier production of pasteurized beverages
packed in hermetically sealed containers, for small-sized enterprises in rural areas and officers
in charge of production control.
According to research and monitoring sessions by the Food and Drug Committee, the
Ministry of Public Health, most small-scale producers of pasteurized beverages packed in
hermetically sealed containers have limited knowledge of the production process, appropriate
use of temperature level and pasteurization period for the treatment of microorganisms, but
still suffer cross contamination after heat treatment. In addition, preparation of materials and
producing instruments are inappropriate; creating microorganism-contaminated products,
which push risks to consumers.
In this study, an appropriate-pattern video presentation was designed and produced to
provide knowledge to small-scale enterprises and farmwomen groups who run pasteurized
beverage businesses in 14 southern provinces of Thailand. The production of content in the
video presentation was based on a review of related literature, some information obtained from
related entrepreneurs, and data from experimental studies conducted in a pilot plant of the
Institute of Nutrition, Mahidol University, which aims to prevent and control pasteurized
product contamination. The video tape presentation was designed to convey clear and
comprehensive information on problems, appropriate prevention measures under proper
narration, and visual elements to fit the audiences. The pre-test/post-test sessions of the
presentation were conducted with 38 audience groups of entrepreneurs, group leaders, and
members of farmwomen groups in Phuket, Krabi, and Song Khla Provinces. The audiences
knowledge before and after the video presentation, including the sample groups satisfaction to
the video presentation were measured.
It was found that the audiences knowledge scores in the post-test increased a great
extent after the video tape presentation. A comparison of average scores in the pre-test and
post-test, gained from different audience groups classified by education level, age, and status
in the enterprise or farmwomen group, found that scores of both tests were different in every
audience group.
The study shows that the designed presentation was appropriate for promoting
knowledge of pasteurized beverages packed in hermetically sealed containers to small-sized
entrepreneurs and farmwomen groups, and therefore further improves safety of pasteurized
beverages packed in hermetically sealed containers, and benefits quality and healthier products
for consumers.
