Rheological Behaviour, Freezing Curve, and Density of Coffee Solutions at Temperatures Close to Freezing
(International Journal of Food Properties, 2014-10-30)
The physical properties of coffee solutions were determined for temperatures close to the freezing point. Rheological behaviour, freezing curve, density, and their relationship between coffee mass fraction and Brix degrees ...
Freezing point and thermal conductivity of tropical fruit pulps: Mango and papaya
(2007-01-01)
The freezing point depression of mango and papaya pulps was measured by using a simple apparatus, consisting of two major sections: a freezing vessel and a data acquisition system. The thermal conductivity of both pulps ...

Ecophysiological strategies to daily air temperature variations in two key species in the northwestern slope of the superpáramo of the Antisana volcano
(PUCE, 2016)
Background: Tropical alpine plants experience daily freezing risk, yet little is known about the
interaction between their surroundings and thermal traits. Existent studies are based on
information taken over short periods ...
BLOCK FREEZE CONCENTRATION OF AQUEOUS COFFEE SOLUTIONSCrioconcentración en bloque de soluciones acuosas de café
(Vitae, 2012)
Freeze concentration is a technique for solutions dewatering by cooling and freezing until the formation
and separation of ice crystal of high purity. This technique avoid quality loss by thermal degradation
of concentrated ...
Some thermal properties of fresh and osmotically dehydrated Kiwifruit above and below the initial freezing temperature
(Elsevier, 2008-09)
Thermal properties of fresh and osmotically dehydrated Kiwifruit were experimentally measured. Enthalpy and heat capacity, in the range from −40 °C to 40 °C, and initial freezing temperature were determined by DSC. Density ...
Freeze casted porous ceramics
(Universidad EAFITDoctorado en IngenieríaEscuela de IngenieríaMedellín, 2020)
Scientists have explored different manufacturing methods aiming at obtaining synthetic materials with controlled porosity, among them, Freeze Casting allows a control of the pore characteristics formed within the material ...
Warmer Temperatures Affect the in situ Freezing Resistance of the Antarctic Vascular Plants
(2018)
Although positive effects on growth and reproduction of Antarctic vascular plants have been reported under warmer temperatures, it could also increase the vulnerability of these plants to freezing. Thus, we assessed in ...
Annual and perennial high‑Andes species have a contrasting freezing‑resistance mechanism to cope with summer frosts
(Springer, 2020)
In high-mountain habitats, summer frosts have negative consequences for plant fitness, therefore high-mountain plants have
developed mechanisms of avoidance and tolerance to cope with freezing temperatures. Various ...
Freezing and Thawing
(Crc Press-taylor & Francis Group, 2012)
Freezing is an important operation in food preservation, for it involves millions of
tons of food per year (Pierce 2002). During freezing, ice formation begins at a temperature Tif, characteristic to each type of foodstuff, ...
