  1. 1. Suspensions of Calcium Phosphate : Interactions of milk proteins to hydroxyapatite

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Ying Chen; [2023]
    Keywords : Calcium fortification; Milk proteins interactions; Colloid chemistry; Food technology; engineering and nutrition; Agriculture and Food Sciences;

    Abstract : Capolac is a product containing hydroxyapatite (HA) from Arla Food Ingredients, to be used for calcium fortification. The adsorption of casein and whey proteins onto the Capolac was investigated, aiming to solve the sedimentation problem of this insoluble calcium phosphate. READ MORE

  3. 2. Effect of the Cooling Rate and the Surface Film Composition on the Colloidal Stability of Whey Protein Based Emulsions of Triacylglycerols

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Charlotte Schüler; [2022]
    Keywords : Emulsion technology; Fat crystallization; Emulsified triglycerides; Colloid science; Food technology; Agriculture and Food Sciences; Technology and Engineering;

    Abstract : The goal of this project was to investigate the effect and interplay of formulation and processing parameters on the colloidal stability of emulsified triacylglycerols from a product quality perspective. Different methods to quantify and monitor this effect over time were evaluated. READ MORE

  4. 3. Effects of melatonin and Single Layer Centrifugation on cryosurvival of ram semen samples

    University essay from SLU/Dept. of Clinical Sciences

    Author : Lea Enenkelová; [2021]
    Keywords : sheep reproduction; Jezersko-Solčava sheep breed; colloid centrifugation; melatonin;

    Abstract : The composition of the ram sperm membrane renders it vulnerable to injury during cryopreservation. Production of reactive oxygen species, which are by-products of metabolism, increases during freezing and thawing, causing damage to sperm membranes and acrosomes as well as affecting mitochondrial activity.

  5. 4. Quantification using SERS on a colloidal substrate

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Kasper Eliasson; [2021]
    Keywords : SERS; spectrometry; nano technology; plasmonics;

    Abstract : This thesis explores the practical usefulness of surface enhanced Raman spectroscopy on a colloidal substrate for quantification of organic analytes in a water matrix. The method evaluated is very simple and accessible as it utilizes a commercially available hand held Raman spectrometer and citrate reduced silver colloid substrate. READ MORE

  6. 5. Effect of lipid-based formulation on the solubilization patterns if poorly water-soluble drugs.

    University essay from Uppsala universitet/Institutionen för farmaci

    Author : Manjiri Gude; [2021]
    Keywords : Lipid based formulations LBFs ; poorly water-soluble drugs PWSDs ; solubility studies; coarse grained molecular dynamic simulations; solubilization; dog intestinal fluid DIF ;

    Abstract : Poorly water-soluble drugs (PWSDs), to date, require advanced formulation techniques to improve solubility and achieve the required plasma concentration to show a therapeutic effect when orally administered. Lipid-based formulations (LBFs) are an enabling strategy that is being used to improve the oral delivery of PWSDs. READ MORE
