  1. 11. Wastewater from a biodiesel plant: characterization of streams and suggestions for treatment options

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Linnea Andersson; [2017]
    Keywords : water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Abstract : Biodiesel is an important alternative to ordinary diesel when limiting the effects on the climate. However, the production path of biodiesel produces a wastewater with a high chemical oxygen demand (COD) and it needs to be cleaned. The aim of this study was to characterise biodiesel wastewater as well as to suggest treatment options. READ MORE

    Abstract : Försök med att driva motorer på rapsoljebaserade bränslen har varit aktuella sedan början på 1980-talet. Trots kraftigt minskad miljöbelastning i form av koldioxidutsläpp och i flera fall även möjlighet till ekonomisk vinning är användningen i lantbruket låg. READ MORE

  4. 14. The effect of rapeseed oil and palm oil supplement and milking frequency on milk yield and milk fat quality

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Sofia Lindman; [2014]
    Keywords : fat supplement; milking frequency; milk fat composition; FFA; milk fat globule;

    Abstract : Milk fat is an important feature in many different milk products and other foodstuffs and it is often crucial for the dairy plants that the milk fat is stable for different manufacturing processes. Lipolysis is the enzymatic degradation of fat and is the one of the causes for an elevated amount of free fatty acids (FFA) in milk. READ MORE

  5. 15. Effects of palmitic and stearic acids supplementation on milk yield, composition and milk lipolysis in dairy cows

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Caroline Robertsson; [2013]
    Keywords : lipid supplement; FFA; free fatty acids; milk fat globules; in vivo digestibility;

    Abstract : When facing the fact that high yielding dairy cows has an increasing energy requirements, the practice of adding lipid supplements such as concentrates rich in palm oil and/or palm oil industry by-products become more common. Palm oil containing high levels of C16:0 causes high levels of free fatty acids (FFA) which are linked to larger milk fat globules (MFG) which affect the reaction of lipolysis resulting in rancid flavour and processing problems.
