Preservatives Tool for Vegetables and Fruits with Photocatalytic N-TiO2/chitosan
Cases of food poisoning that occur in the community of people due consuming food that contain pathogenic bacteria and other toxic substances need to be wary of us. Safe food is food that is not contaminated, it does not contain microorganisms or bacteria and harmful chemicals, have been processed in a manner that properly so that the nature and nutrients are not damaged, and do not disturb the health of people.Vegetables and fruit is a source of vitamins and minerals that necessary body to regulate processes in the body. Although the needs of it is relative small, but the function of vitamins and minerals can hardly be replaced so that the requirement for the consumption of these substances is essential. Some types of vegetables and fresh fruits consumed potentially injurious to health for vulnerable contaminated with microbes and pesticides. This study describes the synthesis of N-TiO2 / chitosan and photocatalyst mechanism in tackling the rot in vegetables and fruits. Chicory and tomatoes used in this study. Tool made cuboid and there is glass coated N-TiO2/chitosan. Based on that observations obtained, white mustard in the refrigerator is more durable than white mustard with no refrigerator and this tool, with a duration of one week storage period. While in tomatoes showed the best results with these tools that compared with a refrigertor and without a refrigerator with storage time up to 2 weeks.
