Technological viability and bioaccessibility of folic acid added to conventional and ready to eat meat products manufactured using e-beam irradiation treatment meat and meat products are one of the most important foods in the diet but, during the las t years, they have been related with diseases like cardiovascular, obesity, diabetes or certain types of cancer. This fact contributes to a decrease in consumption. therefore, scientists and meat industry have made efforts to innovate and bring to ma rket new meat products, according to nutritional guides. A good option could be the development of functional meat products. In this way, one of the strategies used is the incorporation of bioactive compounds (fiber, proteins, antioxidants, minerals, etc.). sometimes it is necessary to modify the manufacturing processes in order to obtain final products with the required nutritive value and sensory properties. There are other interesting ingredients, which have not been studied yet despite their importance in human health. One of them is folic acid, an essential vitamin associated with the prevention of certain diseases and which intake has been recommended by different regulatory authorities, such as the fda (food and drugs administration) and the who (word health organization). on the other hand, in our society, the type of life has changed the eating habits, making more frequent fast, prepared or semi-prepared foods, nutritive and safe, which could be consume with scarce or without culinary treatment. They are the ready to eat products (rte). Their manufacture implies a manipulation that is associated with the presence of pathogen and spoilage microorganisms, which could growth in refrigeration conditions and limit the shelf-li fe of the foods. For that reason, it is necessary to apply an additional treatment to guarantee the microbiological quality. One of the best options is the use of non-thermal technologies, such as the irradiation treatment. functional meat products cannot remain indifferent to this trend and it seems that, in a next future, they will be prepared as conventional rte products. Thus, it is important to know if this technology affects not only the general quality of the product but also the bioacc essibility of the added bioactive compound, the folic acid in this case. few works have been performed in this area. the objectives of this work have been the following: a) to determinate the technological viability of folic acid as functional ingred
