Diagnostic Ultrasound, a non-destructive approach for quality evaluation of Agro-food products

There are many approaches for food quality and safety evaluation and adulteration detection of agro-food products. These ways include destructive and non-destructive. After non-destructive tests, foods can be used and also we can apply all experiment case studies for testing but in destructive test we can test just afew samples. Ultrasound is one of non-destructive tests which can use in quality evaluation and fraud detection of agricultural, livestock and poultry products. Also from detection of foreign body in packaged and canned foods to microbial contaminant detection by ultrasound technique is available. Diagnostic ultrasound in food science is fast, low cost, portable and easy to lean. In this work, evaluation and application of diagnostic ultrasound has been classified in three parts which include: a. agricultural products b. livestock and poultry products and c. vegetable oils, juices and other drinking. At the end on paper challenge and some difficulties in ultrasound are given and some problems for solve and reduction of these challenges are given.
