A new mathematical model based on Michaelis Menten (MM) kinetics is developed to predict the changes in molecular weight distribution (MWD) during the enzymatic depolymerization of guar galactomannan. The model accounts for the effect of branching by considering the guar molecule as a substrate having three types of bonds with different MM kinetic parameters. The overall kinetics of the enzymat...

Biogenic sulfide production is a common problem in the oil industry, and can lead to costly hydrocarbon processing and corrosion of extraction infrastructure. The same phenomenon has recently been identified in shale gas extraction by hydraulic fracturing, and organic additives in fracturing fluid have been hypothesized to stimulate this process. Constraining the relative effects of the numerou...

Twenty-three laboratories participated in a collaborative study to compare the relative effectiveness of Rappaport-Vassiliadis (RV) medium incubated at 42 degrees C, selenite cystine (SC) broth (35 degrees C), and tetrathionate (TT) broth (35 and 43 degrees C) for recovery of Salmonella from the following foods with a low microbial load: dried egg yolk, dry active yeast, ground black pepper, gu...

The aim of this work is to understand the effects of the rheological and interfacial properties of a model food on continuous foaming operation in laminar flow conditions. The rheological properties of food model (glucose syrup) were adjusted using three polysaccharides: xanthan, LM pectin and guar. Interfacial properties were varied using two kinds of proteins: Na-caseinates and whey proteins ...

The study was designed to investigate the impact of colonic pH changes on formulated colon targeted Mesalamine matrix tablets in the treatment of inflammatory bowel disease (IBD). Mesalamine tablets were fabricated with guar gum as Polymer system. The different batches of Mesalamine tablets (GMM1GMM6) were compressed with increasing proportion of guar gum and HPMC E15 LV. The different buffer c...

introduction: morus alba, known as white mulberry, is a short-lived, fast-growing and small to medium sized mulberry tree, which grows to 10–20 meters tall. the species is native to northern china, and is widely cultivated and naturalized elsewhere. the fruit is 1–2.5 cm long in the species in the wild, it is deep purple, but in many cultivated plants it varies from white to pink, being sweet a...

ABSTRACT Acerola and jambolan are fruits with several bioactive compounds of phenolic origin a product made these two raw materials appears to be food high antioxidant nutraceutical potential. Therefore, this study aimed evaluate the foam mat drying mixed pulp acerola. Mixed formulations, containing 1.0% albumin 0.5% xanthan gum (F1), carboxymethylcellulose (F2) guar (F3), were dehydrated at 50...
