This research investigated the application of 915 MHz microwaves in pasteurizing pre-packaged vegetables. A specially designed 915 MHz single-mode microwave-assisted pasteurization (MAP) system was used to process carrot cuboids in brine pre-packaged in 8-oz polymer pouches. Gellan gel was formulated and selected as the model food to simulate the real foods processed by the MAP system; heating ...

An obligatory heterofermentative lactic acid bacterium, Lactobacillus wasatchii sp. nov., isolated from gassy Cheddar cheese was studied for growth, gas formation, salt tolerance, and survival against pasteurization treatments at 63°C and 72°C. Initially, Lb. wasatchii was thought to use only ribose as a sugar source and we were interested in whether it could also utilize galactose. We conducte...

The abundance of fresh drinks based on fruit juices, especially citrus juices, and minimally processed products allow consumers to ingest a wide variety of antioxidants in the diet, such as vitamin C, carotenoids, flavonoids and other phenolic compounds. Pulsed electric fields (PEF) and high hydrostatic pressure (HHP) are emerging technologies in the field of food preservation. They have the po...

Polyhemoglobin-superoxide dismutase-catalase-carbonic anhydrase (Poly-[Hb-SOD-CAT-CA]) contains all three major functions of red blood cells (RBCs) at an enhanced level. It transports oxygen, removes oxygen radicals and transports carbon dioxide. Our previous studies in a 90-min 30mm Hg Mean Arterial Pressure (MAP) sustained hemorrhagic shock rat model shows that it is more effective than blood...

Background: The xoconostle (Opuntia joconostle Web.) plant is produced mainly in the Central Highlands region of Mexico. The main aim of this research was to determine the effect of pasteurization on chemical and functional properties of xoconostle juice. Methods: Total Soluble Solids (TSS), pH, Titratable Acidity (TA), total phenolic and flavonoid content, betacyanins, betaxanthins, and red...

The stability of the antifungal activity of flaxseed (Linum usitatissimum) protein extract was evaluated in this study. Response surface methodology (RSM) using Box-Behnken factorial design was used to evaluate the effects of treatment variables, that is, temperature (50 to 90 degrees C), time (1 to 29 min), and pH (2 to 8), on the residual antifungal activity (RAA) against Penicillium chrysoge...

This research investigated the influence of 915 MHz microwave-assisted thermal pasteurization and conventional hot water (F9010=10 min) on chlorophylls, greenness (a*), ascorbic acid, growth spoilage microorganisms in green beans storage at 10, 7, 2 °C for up to 100 days. Frozen cut were processed vacuum-sealed containers flushed with N2. The suffered 28.3% 33.9% losses chlorophyll a, 9.2% 15.3...

Pasteurization is a thermal treatment applied to the milk used in human milk banks so as to provoke the thermic inactivation of pathogenic micro-organisms, with the aim of avoiding contamination of milk that will be offered to new-born infants in clinical conditions very often demanding special care. The literature has very little data available relating to the effect of pasteurization on the c...

I study the connection between the invention of new technologies and the rise and incumbency of leaders within an industry. I focus on the rise of Midwestern breweries in the US after the invention of pasteurization in the late nineteenth century. Pasteurization reduced the marginal cost of shipping beer for breweries willing to build bottling plants. Using a brewery-level dataset that I constr...
