Surveys
Usually, bacterial contamination cannot be recognized with naked eyes and many people may eat unsafe yogurt by mistake. We checked the current detecting methods and found that traditional methods contain many cumbersome steps and cannot be used in daily life. So shall we find an easy and handy approach to detect pathogenic bacteria in yogurt? From April 15th to 20th, 2015, we did an online survey among 640 individuals to identify whether our idea was worthy to proceed.
Our survey contained questions about the common sense regarding yogurt and yogurt spoilage. We intentionally distributed our e-questionnaire among people of different ages and backgrounds. The results for questions that have greatly impacted our project are shown below.
According to the result, yogurt is a common food and good for human health. Most people eat yogurt frequently. So it means a lot to reduce the adverse affect caused by spoiled yogurt.
More than half of the people would determine the yogurt quality by the expiration date which appears to be unreliable when yogurt is stored improperly. The appearance of spoiled yogurt may be indistinguishable from the eatable ones. So there are still hidden risks with food safety.
Yogurt is generally safe for eating within the expiration date if it is stored in cold; otherwise it may spoil prior to that date. We have searched the Internet and have found varieties of news about yogurt spoilage within shelf-life. This appeared to be a frequently happening phenomenon, but many people are not aware of it.
More than three quarters of people would eat yogurt with very close expiration dates. Moreover, according to our statistical data, 80% would still eat the yogurt just before its expiration, although they realized that yogurt may spoil before the expiration date.
The results of our investigation convinced us that developing a handy and reliable yogurt detecting approach, or “yogurt guarder” named by us, is indeed necessary. This survey do have a great impact on the initiation of our project, since the feedback informed us an urgent need of this detecting method and gave us faith to continue our project. We hope that our ideas can also inspire other teams with similar purposes in the future.
