Peruvian Union University is a Seventh-day Adventist university in Lima, Peru. It is the second largest of ten Adventist universities in South America. Its acronym is "UPeU". Founded in 1919 as Instituto Industrial in Miraflores, Lima, it was the first higher education facility started by Seventh-day Adventists in Peru. Wikipedia.

Some physicochemical and thermal properties of starch from Mirabilis jalapa L, seeds were evaluated. The starch was extracted after hulling and grinding the seeds and the flour obtained was suspended in 0.1% (m/v) NaOH solution for 12 h at 30 °C; it was then centrifuged, re-suspended, washed with deionised water and dried in an oven with circulating air at 40 °C for 12 h. The micro-images of starch granules were performed by using scanning electron (SEM) and non-contact atomic force microscopy (NC-AFM) techniques; X-ray diffraction and mid-infrared spectroscopy were both used to evaluate the relative crystallinity of the starch granules. Thermal analyses TG/DTG and DSC, were applied for the analysis of thermal behaviour of this starch and the cooking behaviour of its aqueous solution was studied by using a viscometer RVA. Thermogravimetry showed that once dehydrated, the starch was stable up to 292 °C after which two steps of decomposition occurred, which were attributed to decomposition and oxidation of organic matter, respectively. The gelatinisation temperature and enthalpy, as assessed by DSC analysis, were 82.1 °C and 5.67 J g-1, respectively. RVA analysis showed pasting temperature of 76.4 °C, with a low viscosity peak at 95 °C, low breakdown, and high tendency to retrograde during cooling. Microscopic results reveal that the starch granules had a spherical shape and 67.4% of them presented diameters smaller than 890 nm. The X-ray diffractogram showed a typical A-type pattern and a relative crystallinity of 34% with a FTIR of 1047/1022 cm-1 and a ratio of 1.38. © 2015 Elsevier B.V. All rights reserved. Source

Microencapsulation of flax oil was investigated using zein as the coating material. Central Composite Design - Face Centered was used to optimize the microencapsulation with respect to zein concentration (x1) and flax oil concentration (x2) using spray drying. Also, freeze drying was carried out at two zein:oil ratios. The quality of microcapsules was evaluated by determining encapsulation efficiency, flowing properties (Hausner ratio), and evaluating the morphology with scanning electron microscopy. The response surface model for microencapsulation efficiency showed a high coefficient of determination (R2 = 0.992) and a non-significant lack of fit (p = 0.256). The maximum microencapsulation efficiencies were 93.26 ± 0.95 and 59.63 ± 0.36% for spray drying and freeze drying, respectively. However, microcapsules prepared by spray and freeze drying had very poor handling properties based on the Hausner ratio. The bulk density decreased with an increase in zein concentration at the same flax oil concentration. The morphology of the flax oil microcapsules depended on the zein:flax oil ratio and the process used for microencapsulation. Flax oil microcapsules prepared by spray drying appeared to be composed of heterogeneous spheres of various sizes at high zein:flax oil ratios. Microcapsules prepared by freeze drying resulted in agglomerated small spheres. These microcapsules might find a niche as functional food ingredients. © 2011 Elsevier Ltd. Source
