“High pressure homogenization (HPH) is one of the most promising alternatives to traditional thermal treatment for food preservation and diversification. In order to evaluate its potential for the production of fermented milks carrying probiotic bacteria, four types of fermented milks were manufactured from HPH treated and heat treated (HT) milk with and without added probiotics. Microbiological, physicochemical and organoleptic analyses were carried out during the refrigerated period (35 d at 4 degrees C). HPH application
to milk did not modify the viability of the probiotic cultures but did increase the cell loads of the CX-6258 mouse starter cultures (ca. 1 log order) compared with traditional products. GW4869 in vivo The coagula from HPH-milk was significantly more compacted (P<0.05) (higher firmness) than that obtained with HT-milk, and it had the highest values of consistency, cohesiveness and viscosity indexes compared with fermented milks produced without HPH treatment. All the samples received high sensory analysis scores for each descriptor considered. HPH treatment of milk can potentially diversify the market for probiotic fermented milks, especially in terms of texture parameters.”
“The phase transformation and morphology of calcium phosphate prepared by the electrochemical
deposition (ECD) process through alkali treatment and calcination have been characterized using X-ray diffraction (XRD), thermogravimetry and differential thermal analyses (TG/DTA), and scanning electron microscopy (SEM). At the ECD process, when the excess OH- was produced, the reaction of 10Ca(2+)+6PO
(4) (3-) +2OH– bigger than Ca-10(PO4)(6)(OH)(2) takes 4SC-202 nmr place on the Ti-6Al-4V and the HA is deposited. The XRD results reveal that the as-deposit was mostly composed of dicalcium phosphate dehydrate (Ca2H4P2O9; DCPD) and the minor phase of hydroxyapatite (Ca-10(PO4)(6)(OH)(2); HA). After NaOH treatment, all DCPD were converted to HA. Moreover, the content of HA phase increases with ECD potential. After being calcined at 673 K and 873 K (400 A degrees C and 600 A degrees C) for 4 hours, the phase of HA maintained the major phase for an alkali-treated deposited sample. After being calcined at 1073 K (800 A degrees C) for 4 hours, some HA decomposed and caused the minor phases of beta-tricalcium phosphate (beta-Ca-3(PO4)(2); beta-TCP), calcium pyrophosphate (Ca2P2O7; CPP), and calcium oxide (CaO) formation. The beta-TCP becomes the major phase with residual HA and CaO after being calcined at 1273 K (1000 A degrees C) for 4 hours. The crack forms due to the release of absorbed water from the interior to top surface of sample.
