Abstract The phenolic compounds and antioxidant activity of brown rice are well known but the extent to which phenolics and antioxidant activity varies within rice (Oryza sativa) is not known. This study evaluated the natural variation of phenolic compounds in brown rice of the major cultivars currently grown in China. Free phenolics were extracted with chilled methanol, while bound phenolics were released and extracted by alkaline hydrolysis. There were significant differences in phenolic and flavonoid content between these cultivars and significant differences in bound and total phenolics be

Globally, cancer is the second leading cause of death. Different conventional approaches to treat cancer include chemotherapy or radiotherapy. However, these are usually associated with various deleterious effects and numerous disadvantages in clinical practice. In addition, there are increasing concerns about drug resistance. In the continuous search for safer and more effective treatments, plant-derived natural compounds are of major interest. Plant phenolics are secondary metabolites that have gained importance as potential anti-cancer compounds. Phenolics display a great prospective as cyt

Ferulic acid is a secondary metabolite usually found as esters in plants and dihydrocaffeic acid results from the microbial metabolism of flavonoids and of caffeic acid, both widely distributed in food. Even though ferulic acid and flavonoids have been proposed to exert several beneficial effects on health, their in vivo activities could partly result from their microbial metabolites and strongly depend on their bioavailability.

Mitigation strategies include process solutions such as wash water systems and temperature control, and chemical solutions including amine-based neutralizers and film-forming inhibitors. Despite implementing these strategies, corrosion is invariably observed in the overhead system. Conventional “non-volatile” filmers rely on f

Abstract Biomass-derived pyrolysis oils are rich in carbon and can be used as such or can be processed to produce oil compatible with crude oils to be used in production of fuel and chemicals in petroleum refineries. However, pyrolysis oils can be significantly more corrosive compared to traditional fuels. As-produced pyrolysis oils contain a significant amount of oxygen, primarily as a component of water, carboxylic acids, phenols, ketones and aldehydes. As a result of these constituents, bio oils are generally more acidic with a total acid number (TAN) that can reach levels as high as 100mgK

These challenges arise primarily from a requirement for enhanced and long-life lining performance in aggressive and acidic feedstocks used in the manufacturing processes. This paper investigates the degradative effects and mechanisms on linings imm

Abstract:

Beer is one of the most famous beverages in the world, produced using a standardized technology that includes barley malt, water, hops and brewer's yeast. However, consumers demand for innovative and authentic beer have been contributed to the development of microbreweries and the production of craft beer. In recent years, there has been an increasing focus on the production of "functional" craft beers with unique sensory properties that contain non-cereal adjuncts. A particular challenge in the development of these craft beers is the manner and timing of the addition of adjuncts in the brewin

Abstract:

The phenolic content of investigated Rosa dumalis fruit samples were studied. To obtain a more detailed phenolic profile, five solvents with different polarities (water, ethanol, 60% ethanol, methanol and acidified 80% methanol) were used for the preparation of the plant extracts. Individual phenolics were analyzed using high performance liquid chromatography (HPLC). The obtained results indicate that the investigated R. dumalis samples are rich in both phenolic acids and flavonoids. Acidified 80% methanol extracts had the highest yields followed by the 60% ethanol, water, methanol, and ethano

Abstract:

Phenolics found in various crops and by-products have antioxidant and antimicrobial activities and their consumption have been associated with health benefits. For example, a by-product of the cranberry juice industry is cranberry pomace, which is considered a rich source of anthocyanins. Research in my laboratory has focused on the use of pressurized fluids to extract these phenolic compounds to be used in various applications. Pressurized fluids, such as subcritical water, pressurized ethanol and supercritical CO2 (SC-CO2) as â€œgreenâ€ and environmentally friendly solvents, can be used for

Abstract:

Several grape varieties and red wines were found to contain large concentration of phenolic compounds which work as antioxidant in-vitro and in-vivo. Wastes from wine production contain antioxidants in large amounts, between 2-6% on dry material basis. Red wines but also white wines were found to prevent lipid peroxidation of turkey muscle tissues stored at 5oC. The antioxidant reaction of flavonoids found in red wines against lipid peroxidation were found to depend on the structure of the molecule. Red wine flavonoids containing an orthodihydroxy structure around the B ring were found highly

Abstract:

Monilinia fructicola causes brown rot blossom blight and fruit rot in stone fruits. Immature fruit are highly resistant to brown rot but can become infected. These infections typically remain superficial and quiescent until they become active upon maturation of the fruit. High levels of chlorogenic acid (CGA) and related compounds occur in the peel of immature fruit but these levels decline during ripening. CGA inhibits cutinase expression, a putative virulence factor, with little or no effect on spore germination or hyphal growth. To better understand the regulation of cutinase expression by

The objective was to screen maize lines for their ability to express resistance based on biochemical traits. Cultivars were screened for retention of the hydroxamic acid DIMBOA and the synthesis of phenols (based on anthocyanin production) as markers for resistance. Lines were selected and inoculated with fungal pathogens (Exserohilum turcicum, Puccinia sorghi, Cochliobolus heterostraphus, Colletotricum graminicola.), and the Maize Dwarf Mosaic and Johnson Grass Mosaic viruses. Lines were screened in the field and greenhouse. Results showed that lines selected for augmented phenol synthesis do

Abstract:

Our study was designed to elucidate the chemical determinants of pectin cross-linking in developing fruits of apple and peach and to evaluate the role of breakage cross-linkages in swelling, softening, and cell separation during the ripening. Peaches cell walls soften and swell considerably during the ripening, whereas apples fruit cells maintain wall firmness but cells separate during late stages of ripening. We used a "double-reduction" technique to show that levels of non-methyl esters of polyuronic acid molecules were constant during the development and ripening and decreased only in overr
