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. Continuous leaching of phosphorus from sewage sludge ash

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

   Author : Sofie Göransson; [2022]
   Keywords : Ash leaching; Continuous stirred tank reactor; CSTR; Phosphorus recovery; Sewage sludge ash;

   Abstract : The global demand for food is increasing. Different nutrients are used to increase growth in agriculture and are thus essential for the world ́s food supply. An important and common nutrient is phosphorus. It can be mined, in the form of phosphate, from phosphate rock. READ MORE

4. 3. Prolongation of shelf life of minimally processed spinach by combining vacuum impregnation and electric field treatments

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

   Author : Sophia Leffler; [2022]
   Keywords : spinach; pulsed electric field; moderate electric field; reversible electroporation; vacuum impregnation; shelf life; metabolic activity; respiration; food engineering; Agriculture and Food Sciences;

   Abstract : A continuous growth of the world population raises the importance of preserving food resources while maintaining their nutrient value. Leafy vegetables such as spinach are a food category which decay quickly, and a large amount ends up as food waste. READ MORE

5. 4. Future diagnostic of Sepsis : Biomarker miRSeps-5 manual vs robotic extraction and optimization of miRNA detection by Two-Tailed RT-qPCR technology

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Erika Kasaras; [2022]
   Keywords : ;

   Abstract : Sepsis is a syndrome developed in response to infection when a body’s immune system cannot adequately respond to infection. To this day, sepsis holds a peak position in mortality rates worldwide. Currently, SOFA score and blood culturing as means to diagnose sepsis are standard. READ MORE

6. 5. Lipase in oat endosperm: The effect of freeze-drying and oven-drying

   University essay from Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

   Author : Ilham Hassan; [2021]
   Keywords : Lipase; oat endosperm; whole grain oat flour; water activity.;

   Abstract : The project was carried out in collaboration with Lantmännen with the aim to analyse the lipase activity in oat endosperm, non-heat-treated whole grain oat flour and heat-treated whole grain oat flour and to investigate whether lipase activity could be inactivated in oat endosperm by reducing water activity by various methods such as oven drying and freeze drying to extend oat shelf life. Lipase activity was measured by a wet extraction of the flour and an artificial substrate that gives a coloured product if lipase enzymes are active in the extract. READ MORE
