Abstract:
PURPOSE: A method for identifying the mixture of meat ingredients in a food ingredient is provided to enable scientific food monitoring and to block distribution of bad foods. CONSTITUTION: A method for identifying the mixture of meat ingredients in a food ingredient comprises: a step of extracting DNA from the food ingredient; a step of performing PCR comprising first, second, third, fourth, fifth, and sixth steps using the DNA and a primer set; and a step of detecting the presence of meats including bos taurus, sus scrofa, ovis aries, capra hircus, cervus elaphus, cervus Nippon, and equus caballus.
Abstract:
PURPOSE: A method for determining the mixture of a poultry ingredient in a food using a primer set comprising a forward primer of a certain sequence and a reverse primer of a certain sequence is provided to scientifically monitor foods for prevent distribution of bad foods. CONSTITUTION: A method for determining the mixture of a poultry ingredient in a food comprises: a step of isolating DNA; a step of performing first, second, third, and fourth PCR using a primer set and the DNA as a template; and a step of detecting the poultry ingredient. The primer set is selected from the group consisting of: a primer set comprising a forward primer in sequence number 1 and a reverse primer in sequence number 2 for detecting Gallus gallus; a primer set comprising a forward primer in sequence number 3 and a reverse primer in sequence number 4 for detecting Anas platyrhynchos; a primer set comprising a forward primer in sequence number 5 and a reverse primer in sequence number 6 for detecting Meleagris gallopago; and a primer comprising a forward primer in sequence number 7 and a reverse primer in sequence number 8 for detecting Struthio camelus.
Abstract:
PURPOSE: A critical temperature indicator and a manufacturing method thereof which displays critical temperature of freezing and refrigerated food are provided to make mass production and to display a red sign. CONSTITUTION: A critical temperature indicator comprises a lower part(20), a development medium member(21), a time controller, transparent members(40,45) and an upper part. The upper side is dyed in red or the lower part is formed in the base film. The development medium member absorbs the development material. The time controller adheres to the lower part and development medium member. The transparent member is piled up on the development medium member. The transparent member comprises a first display(42) of linear type. The upper part is composed of the opaque body layer equipped with a molding part.
