  1. 1. A new generation ofsmart food packaging : A combination of releasing anti-microbial and generation carbon dioxide inmeat packaging

    University essay from Karlstads universitet

    Author : samar salahieh; [2023]
    Keywords : adsorption isotherms; desorption kinetics; benzoic acid; thymol; modified calcium carbonate; silica gel; carbon dioxide; food pad.; adsorptionsisotermer; desorptionskinetiken; bensoesyra; tymol; modifierat kalciumkarbonat; kisel gel; koldioxid; food pad.;

    Abstract : Abstract Food sustainability depends significantly on packaging since it helps maintainfood safe and fresh throughout its shelf life, resulting in the least amount ofwaste and the least negative environmental impact. The main objective of thisstudy is to determine the adsorbed and released amount of antimicrobial agents(benzoic acid and thymol) on modified calcium carbonate (MCC) by investigating adsorption isotherm at 25°C and desorption kinetics at both 22°C and5°C of anti-microbial to identify potential solutions to enhance the long-termsustainability of fresh products such as meat.

  3. 2. Detection of Amphetamine with Graphene Quantum Dots

    University essay from KTH/Tillämpad fysik

    Author : Carl Fredrik Åslund; [2021]
    Keywords : Graphene quantum Dots; Amphetamine; Sensor; GQD; Grafen kvantprickar; Amfetamin; Sensor; GQD;

    Abstract : Amphetamine abuse is an enduring problem in many developed nations, including Sweden. It causes lasting damage both to its users and in the form of increased strain on healthcare services. It is therefore critical that police be equipped with the tools necessary to rapidly and accurately identify any samples in order to combat this scourge. READ MORE

  4. 3. Converting Poultry Feather Waste into Bioplastics using Green Modifying Agents

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Marc Jirström; [2021]
    Keywords : polymer technology; materials science; renewable materials; Technology and Engineering;

    Abstract : Handling of problematic waste material, and the use of fossil-based and non-biodegradable plastics are two major sustainability challenges. By developing solutions that convert waste material to bioplastics, it is possible to address both these issues. READ MORE

  5. 4. Variation in Swedish bovine raw milk from 1995 to 2020 : focus on composition and properties

    University essay from SLU/Department of Molecular Sciences

    Author : Ylva Eriksson; [2020]
    Keywords : protein; fat; lactose; calcium; citrate; somatic cell count; pH;

    Abstract : The composition and properties of Swedish bovine raw milk are influenced by several factors which have varied over the last 25 years. Factors influencing milk quality include: bovine breed, stage of lactation, type of feed, and climate. READ MORE

  6. 5. Transformation of lignin into biobased thermoset

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Linnea Cederholm; [2018]
    Keywords : lignin; microwave heating; solvolysis; biobased thermoset; lignin; mikrovågsbaserad teknik; solvolys; biobaserad härdplast;

    Abstract : Combined microwave assisted extraction/degradation of technical lignin in green solvents was successfully employed to generate polyphenolic oligomers with lower Mw than the starting material. For Lignoboost, the highest liquid yield (65 %) was obtained in 20 min at 160 °C using ethanol as solvent. READ MORE
