  2. 1. Heat-Induced Cell Membrane Injury of Vegetable Tissues -An applied study on potatoes

    Author : Gerardo Gonzalez-M; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; PME; active transport; Cell membrane injury; potatoes;

    Abstract : Heat processing of vegetables involves the use of temperatures above the physiological limit which affect the cellular structures of the tissue and induce a series of events at cell level that will in turn be reflected in the transport properties of the tissue. One of the most important cellular structures from the mass transport point of view is the cell membrane since it represents the physical barrier to the transport of nutrients into and out of the cell.

  4. 2. Industrially Pre-Treated Potatoes (Solanum tuberosum L.) Served in Large-Scale Food Service Systems

    Author : Klara Sjölin; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Potatoes Solanum tuberosum L. ; large-scale food service system; Industrial pre-treatment; subsurface hardening; Potatoes Solanum tuberosum L. ; subsurface hardening; industrial pre-treatment; large-scale food service systems;

    Abstract : In Swedish schools, a warm lunch is served every day. The lunch is prepared in a largescale food service system and includes steam-cooked potatoes several times per week. The potatoes are often industrially pre-treated to facilitate the handling and logistics required to cook hundreds of meals in a couple of hours. READ MORE

  5. 3. Development of Transgenic Potatoes to Attain Novel Starch Qualities

    Author : Mariette Andersson; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Livsmedelsteknik; Food and drink technology; Biokemisk teknik; Biochemical technology; StGH; starch yield; RNAi; antisense; gene silencing; ahas; potato transformation; sbe2; sbe1; gbss; amylopectin; amylose; Starch; potato;

    Abstract : Starch is a plant-derived polysaccharide with many uses in different food and non-food applications. In this thesis, the production of two novel potato starch qualities, amylopectin and high-amylose, and the modifications and the characteristics of the produced plants and starches are described.

  6. 4. Acrylamide in Potato Crisps - A Three-year Study on Swedish-grown Potatoes

    Author : Gunilla Viklund; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Potato varieties; Asparagine; Acrylamide; Potato crisps; Reducing sugars;

    Abstract : Acrylamide, a probable human carcinogen, has been found at mg/kg levels, in heat-treated carbohydrate-rich foods. Acrylamide is formed via the Maillard reaction as a result of the reaction between the amino acid asparagine and reducing sugars (glucose and fructose). READ MORE

  7. 5. Studies on the different inhibitors of the inhibitor β complex from resting potatoes

    Author : Jeevalatha Franklin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Seasonal changes of the inhibiting substances in the inhibitor B complex were studied in diethyl ether and methanol extracts of peelings from potato tubers (Solanum tuberosum L. variety Majestic), prepared during dormancy and cessation of dormancy. At each extraction time experiments were performed to determine the stage of rest in the tubers. READ MORE
