FDNS 4600 1st Edition Lecture 19Outline of Past Lecture I. Why is there a problem with pasteurization?II. What nutrients are added?III. Increased Outbreaks Associated with Non-pasteurized Milk, US, 2007-2012IV. Does US have Antibiotic- free Milk supply?V. Concerns about milk?Outline of Current LectureI. Types of GMII. Common TechnologyIII. Benefits to animals that eat GM foodsIV. Benefits of GM FoodsCurrent LectureI. Types of GMa. Mutation breedingi. Main foods bananas, pears, apples, rice, yams, mint, othersii. There is no way to assess the number of genes affectediii. Therefore, there is no way to know which genes and where theses genes are. b. Transgenics (rDNA method to add a gene- GMO)i. Corn, canola, soybeans, cotton, papayaii. Only type that requires Environmental assessment.iii. Requires only one to three genes where other types change thousand + genes. This also helps make it specific.c. Consumers are generally unclear about theses terms. Assume GMO is an umbrella term.II. Common Technologya. Herbicide Toleranti. EPSPS help plants make aromatic amino acids.1. As humans, we do not have these genes.b. Insect resistanceThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.i. Kills the insects when they digest it. c. Animal hormonesi. Help the animals be more efficient in productionIII. Benefits to animals that eat GM foodsa. Phytic acid decreases the intestinal absorption by binding phosphorus.b. Phytase is extremely helpful in helping break down phytic acid.c. It also benefits the environment by decreasing the phosphorus excretion into theenvironment.IV. Benefits of GM Foodsa. Cropsi. Enhanced taste and qualityii. Reduced maturation timeiii. Increased nutrients, yields, and stress toleranceiv. Improved resistance to disease, pests, & herbicidesv. New products and growing techniques b. Animalsi. Increased productivity, hardiness, and feed efficiency, along with improved animal health and diagnostic methodsc. Environmenti. Conservation, bioprocessing, natural waste management, and “friendly" bioherbicides and bioinsecticidesd. Societyi. Africa mainly needs GM foods, so it would be assumed that they would want them. However, Europe is anti-GM foods and advises Africa not to want GM foods. ii. There is a lack of education that leads to the fear of GM foodsiii. If the public is so apposed, how is it being planted?1. It is an advantage to the
