Tables 2 – 5 show these results. The microbiological analysis (fig. 2) suggested that the new packages do not affect the development of bacterial and fungal populations naturally contained in pasteurized milk, or the growth of selected pathogenic strains, artificially inoculated in milk and yogurt. It also doesn’t affect the viability of lactic acid bacteria contained in yogurt. In addition, they do not release any significant substances in milk and yogurt stored inside affecting the product. Therefore, the packages fulfill the microbiological requirements established by the product packers. Regarding to the legal requirements based on the Overall Migration, the pouches and both bottles were tested and they do fulfil the requirements, according to European Commission Regulation (EU) No 10/2011 [2]. The use of new biodegradable packaging does not affect the organoleptic properties of the evaluated dairy products. Except for unflavored low-fat yogurt, where a consumer panel revealed small differences between the new bio bottles and the reference bottles. Biodegradability and Compostability The biodegradation under controlled composting conditions was successfully demonstrated for the different developed compounds (fig. 3) and they fulfil the requirements of material characteristics, biodegradation and compost quality according to EN 13432 (2000). Pouches and caps can be concluded to be fully compostable in industrial processes and the OK compost logo and seedling logo were obtained from the certification institute 14 bioplastics MAGAZINE [04/16] Vol. 11

Blow Moulding Vinçotte (Belgium). The bottles did not show sufficient disintegration due to the necessary thickness that the bottles must maintain to fulfill the structural functionality. Economic analysis The economic study revealed that producing newbiodegradable packages for dairy products is still not competitive in price with the existing packages due to the current price of biodegradable raw materials. Market studies predict a decrease in their price because of an increase in the global demand and production. Thus, biodegradable market trends foresee a positive scenario for the BIOBOTTLE packages commercialization in 5 years time. Important is that the cost of the final product with the new biodegradable packages increases less than 10 % in the different packages developed.
