Notes: Jewel sweet potatoes (SP) were prepared as flour and puree of baked and steam-cooked roots. SP replaced 0, 7, 14, and 21% of the wheat flour in a recipe for yeast-raised doughnuts. Composition of doughnuts was apparently affected by type and amount of SP. Caloric content ranged from 6.32–7.03 Kcal/g dry material. Texture and specific volume of doughnuts were affected by SP. Crumb color of doughnuts with SP was yellow-orange. Six quality attributes tested by a panel were affected by SP, but for the most part, overall quality of the doughnuts was not lowered.

Description / Table of Contents: Summary Measurements are referred taken by aRankine viscometer with wound capillary and a performance described in 1965. A special problem of thermostatisation is pointed out as a peculiar source of error. The measurements on the system methanol-methane in the neighbourhood of the condensation of methanol are not to calculate satisfactorily by theEnskog- Chapman theory. A method of empirical correction leads to good results. It is to be concluded by comparison with data from the literature that the type of the isothermal viscositycomposition curve is determined by the methane.

Notes: Zusammenfassung Es wird über Messungen mit einemRankine-Viskosimeter mit gewundener Kapillare und nach einer 1965 beschriebenen Bauart berichtet. Auf ein spezielles Temperierproblem als besondere Fehlerquelle wird hingewiesen. Die Messungen am System Methanol-Methan in der Nähe der Kondensation des Methanols lassen sich nicht zufriedenstellend nach derEnskog-Chapman-Theorie bei kleinen Teilchenzahldichten beschreiben; ein empirisches Korrekturverfahren führt zu guten Ergebnissen. Aus dem Vergleich mit Literaturdaten wird geschlossen, daß der Kurventyp der Viskositäts-Zusammensetzungs-Isothermen durch das Methan bestimmt wird.
