  1. 1. Application of CO2 expanded liquids as green solvents for the extraction of antioxidants

    University essay from Lunds universitet/Kemiska institutionen

    Author : Mar Coto Acosta; [2016]
    Keywords : Carbon-dioxide expanded liquids CXLs ; Solubility; Density; Antioxidants; analytical chemistry; analytisk kemi; Chemistry;

    Abstract : Antioxidants are compounds present in plant, fruit, and vegetables, and they are known for their medicinal benefits such as anti-carcinogenic and anti-fungicidal activity. Most commonly used methods for extractions of such compounds are lengthy due to mass transfer limitations. READ MORE

  2. 2. Dissolution kinetic study of limonene in supercritical carbon dioxide by in-situ Raman spectroscopy

    University essay from Lunds universitet/Kemiska institutionen

    Author : Cristiana Buzolin; [2016]
    Keywords : limonene; Raman spectroscopy; supercritical carbon dioxide; dissolution kinetics; solubility; analytical chemistry; analytisk kemi; Chemistry;

    Abstract : Understanding the dissolution kinetics is important in the experimental determination of solubility, the efficiency of extractions, the rate of reactions and in general any heterogeneous process. Despite the extensive use of supercritical fluids, studies regarding the dissolution kinetics of compounds in supercritical carbon dioxide (scCO2) using analytical methods are limited in the literature.

  3. 3. Shaping the role of water : an investigation of participation and stringency in third-party ecolabels for coffee

    University essay from Lunds universitet/LUCSUS

    Author : Linn Snarset; [2016]
    Keywords : participation; standards; water resources; green coffee; stringency; sustainability science; Social Sciences;

    Abstract : The global food system, population growth, increased wealth, shifting diets and an overall larger demand for processed food, meat and dairy, has led to increased pressure on land, water and energy. The environmental implications of this have taken part in the establishment of international institutions which aims to regulate agriculture production methods, and thereby reduce these adverse impacts.

  5. 5. The Influence of Agroforestry on Soil Fertility in Coffee Cultivations : A Review and a Field Study on Smallholding Coffee Farms in Colombia

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Ida Ekqvist; [2015]
    Keywords : Agroforestry; coffee farming; shade coffee; soil fertility; respiration rate;

    Abstract : Coffee is, together with cacao, the crop most commonly cultivated under shade trees in order to cope with physiological stress (as drought and sun radiation) and erosion as well as to generate additional income for the farmer. However, today this agroforestry coffee management is increasingly transformed into industrial plantation with little or no shade using varieties that tolerates full sun and can be planted with higher density.
