Disadvantages of Food Irradiation:
· It reduces the content of several key nutrients such as Vitamin E (~15-30 %); Thiamin (~10-25%); Vitamin C (5-15%); Riboflavin (~7-10%); Pyridoxine (~10-20%); Vitamin B12 (~15-20%). Other nutrients are also affected however the results are less consistent.
· It creates radiolytic products with unknown short term or long term safety effects.
· Some of the organoleptic properties are affected especially for herbs, spices, essential oils.
· Formation of cholesterol oxides and fatty acid epoxidation and other oxidation products (aldehydes, esters, ketones etc.) posing safety concerns.
· Aggregation of certain proteins has been found for high protein commodities.
· The method is 90-95%% effective in killing microorganisms. The remaining 5-10% remain unaffected and may proliferate thus negating the irradiation steps. The methods can result in 95-100% effectiveness but will substantially affect the quality of the food item (taste, nutrient contents, radiolytic products,denaturing proteins, fatty acids etc.).
· Is ineffective against viruses.
no. I've heard from a bunch of sources even one who does it and thae said no.
Typically, dehydration and irradiation. The causes of most food spoilage is the growth of bacteria in the moist environment of the food. Irradiation can kill all the bacteria, so as long as the package is sealed, no bacteria can grow there. And dehydration removes most of the water from the food so that it takes up less space and weight, and stays edible for longer times.
Depending on the type of the food many methods of preservation exist: adding sugar, salting, irradiation with gammas, freezing, lyophilisation, pasteurization etc.
The chemical equation is:6 CO2 + 6 H2O = C6H12O6 + 6 H2O (by light irradiation)
Food microbiology is applied in various industries for ensuring food safety, quality control, and shelf-life extension. It is used in testing and monitoring for harmful pathogens, spoilage organisms, and probiotic bacteria. Food microbiology also helps in developing and improving food preservation methods, such as fermentation, pasteurization, and irradiation.
in some cases really bad because that might mean that you had an allergic reaction to the food and may need to be hospitalized.

He was irradiated from the UV rays after the ozone hole. This is a sentence using irradiation as a word.
Irradiation preserves food by destroying microbes just as heat does in the canning process. In both processes, the food must have been first sealed in a container e.g., a can, jar, or pouch.
One method of preservating food is by irradiation.
Food irradiation is a process that can help kill harmful bacteria and parasites in food, reducing the risk of foodborne illnesses. It can also extend the shelf life of certain foods by slowing down the ripening process and inhibiting the growth of mold and bacteria. Overall, food irradiation can contribute to improved food safety and preservation by reducing the risk of contamination and spoilage.
irradiation
Yes, it is safe in controlled conditions.
Advantages Can be used to destroy or inactivate organisms that cause spoilage and decomposition Foods that are sterilized by irradiation can be stored without refrigeration for years Offers an alternative to chemicals for use with grains, potatoes, citrus and tropical fruits, seasonings, and spices
