  2. 1. Acid transport through gastric mucus : A study in vivo in rats and mice

    Author : Mia Phillipson; Lena Holm; Henrik Sjövall; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; gastric acid; pH-sensitive microelectrode; mucus; mucosal blood flow; nitric oxide; intravital microscopy; laser Doppler flowmetry; Fysiologi; Physiology; Fysiologi; Physiology; fysiologi;

    Abstract : The gastric mucosa is frequently exposed to endogenously secreted hydrochloric acid of high acidity. Gastric mucosal defense mechanisms are arranged at different levels of the gastric mucosa and must work in unison to maintain its integrity. READ MORE

  7. 5. Aroma Partition and Release from Soft Drinks, Jam, and Jellied Sweets

    Author : Annika Hansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas chromatography; aroma; gel; model mouth; partition coefficient; release; citric acid; pectin; in-nose; sugar; proton-transfer reaction mass spectrometry; soft drink;

    Abstract : The research described in the present thesis was focused on the influence of food ingredients and structures on the partition and release of aroma compounds from model systems such as soft drinks, jam, and jellied sweets. The effects on aroma release were studied during both static and dynamic conditions, the latter by both model mouth and in-nose measurements. READ MORE
