  1. 1. Flow of non-starter lactic acid bacteria : from to silage to raw milk to cheese

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :John Johansson; [2022]
    Nyckelord :Non-starter lactic acid bacteria; herbage; silage; raw milk; cheese; Lactiplantibacillus plantarum; Lacticaseibacillus paracasei; Lacticaseibacillus casei;

    Sammanfattning : Modern cheese manufacturing uses a known starter culture of lactic acid bacteria (SLAB) for the fermentation of lactose to lactic acid. There is, however, often a second fermentation in cheese manufacturing by non-starter lactic acid bacteria (NSLAB). LÄS MER

  3. 2. Aroma components of long ripened cheese and their origin, variation and contribution to flavour : with focus on propionic acid

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Sandra Carlsson; [2021]
    Nyckelord :cheese ripening; aroma components; volatile compounds; metabolism of lactose; lactate and citrate; ; proteolysis; lipolysis; propionic acid bacteria; sensory evaluation;

    Sammanfattning : Flavour compounds in cheese are formed by metabolism of residual lactose, lactate and citrate, proteolysis and lipolysis through the activity of e.g., starter bacteria. Generally identified aroma components in cheese are fatty acids, esters, alcohols, ketones, lactones, aldehydes, and sulphur compounds. LÄS MER

  4. 3. Proteaser i mjölkråvara och mejeriprodukter : fördelar och nackdelar

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Louise Gustafsson; [2020]
    Nyckelord :endogena proteaser; exogena proteaser; mjölkkvalitét; mjölkproteiner;

    Sammanfattning : Enzymer i mejeriindustrin har stor betydelse under tillverkning av mejeriprodukter. Proteaser, en typ av enzym, hydrolyserar mjölkproteiner och kan bidra till positiva såväl som negativa effekter i mjölkråvara och slutprodukt. Proteaser kan ha olika verkan beroende på om de har ett endogent eller exogent ursprung. LÄS MER

  5. 4. Plasmin and plasminogen variation in bovine raw milk : impact of season, breed and milking system

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Jaafar Khaled; [2019]
    Nyckelord :Plasmin; season; breed; milking system; milk composition; plasminogen;

    Sammanfattning : Plasmin (PL) is a native proteinase in milk, which combines a complex system consisting of its zymogen called plasminogen (PG), inhibitors and activators, which activity is known to make considerable changes in the dairy products, which represent in irregulating of casein hydrolysis and poor clotting properties, that may slow the cheese ripening process and consequently increase the processing expense. The objective of this study was to investigate if on-farm factors (i. LÄS MER

  7. 5. Torklagringstemperatur för gryn- och rundpipig ost : Att finna en gemensam torklagringstemperatur för gryn- och rundpipig ost 

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Zandra Dahlqvist; [2016]
    Nyckelord :Ost; viktförlust; Präst 31 %; Präst 17 %; Herrgård 28 %; Grevé 28 %; Grevé 17 %; MilkoScan FT120; torklagringstemperatur;

    Sammanfattning : Cheese making is an old method that originally has been used as a means to preserve milk. More than hundred types of cheeses are produced around the world, varying in bacterial cultures, pressing and ripening conditions. Grevé-, Herrgård- and Prästcheese are all examples of Swedish semi-hard cheeses. LÄS MER
