  1. 1. Cheeses with blowing defect : problematics and preventable methods

    Kandidat-uppsats, SLU/Dept. of Food Science

    Författare :Amanda Alvenäs; [2015]
    Nyckelord :blowing defect; gas defect; cheese spoilage; cheese problems; feljäsning; sprängd defekt; ostförstörelse; ostproblem;

    Sammanfattning : Blowing defect of cheeses refers to undesirable openness of the cheeses interior. It is a result of unwanted microbial metabolism. Production of hard- and semi-hard chesses require methods and/or preservatives to make sure that blowing defect is prevented. LÄS MER

    Sammanfattning : During the summer 2007 was a scrubber tested at Gruvön papper mill in Grums. The scrubber reduced NOx with 90 % in flue gas. NOx was transferred from the flue gas to a scrubber liquid as nitrate and nitrite. The scrubber liquid needs to be purified from nitrate and nitrite. LÄS MER
