The past three decades have seen a global wine glut. So far, well-intended but wasteful and expensive market-intervention has failed to drag the wine industry out of a chronic annual oversupply of roughly 15%. Can yeast research succeed where these approaches have failed by providing a means of improving wine quality, thereby making wine more appealing to consumers? To molecular biologists Sacc...

Methods for the detection of low numbers of heat-resistant molds on fruits were studied by using cultures of Byssochlamys and a number of unidentified mold isolates. Ascospore dormancy had a marked effect on viable recoveries, and the medium in which ascospores were heated influenced activation rates. Best results were obtained when fruit homogenates were heated for 60 min at 70 C in Concord gr...

QA2 Use of Vitamins in Children with Down Syndrome Question A Down Syndrome five month old breastfed infant is given supplemental Nutrivene D and 90 cc Nutramigen formula. The Nutramigen and Nurtrivene D, a powder dissolved in white grape juice, are given via the lactation device at bedtime. The child is thriving on breast feedings and receives Early Intervention Services at the local neuromusc...

Ochratoxin A (OTA) is a mycotoxin produced by Aspergillus and Penicillium genera. It hepatotoxic, nephrotoxic carcinogenic. The growing contamination of OTA in wine grape juice great threat to human. In this study, different enzymes were screened for the detoxification juice. results indicated that seven had degradation capacity buffer, rate carboxypeptidase (CPA), lipase, pancreatin thermolysi...

I. Problem To maintain a competitive edge, the Ozark Table Grape Growers Association, Inc. (OTGGAI) is attempting to develop a strong alternative value added product in a new juice blend. This is necessary to utilize the less desirable grapes which fail to meet the fresh inspection/shipping standards. The Association has completed only its third year of operation and is composed of approximatel...

ABSTRACT: The present research presents an analytical methodology based on High Performance Liquid Chromatography (HPLC) and Principal Component Analyses (PCA) for simultaneous quantification differentiation of organic acids sugars in commercial fruit juice samples (orange, grape, apple tangerine). In addition to the development method that generated suitable validation paramters quantitative a...

Abstract This study aimed to establish if there is any evidence that soil mineralogical and/or chemical composition influence the composition and quality of wine grapes. In the initial phase of the study, soils and grapes were sampled in two riesling vineyards in South Australia. Soils were analysed for a wide range of total major and trace elements; soil cation extracts and grape juices were a...

Dr Al Kobaisi investigated the synthesis and characterisation of a series of Molecularly Imprinted Polymers (MIPs). He employed surface area determinations and other physico-chemical measurements to comprehensively explore the factors influencing their porosity, pore-size distribution and selectivity. In the course of the investigation, an MIP was developed which, when coated as a thin film on ...

Anthocyanin colors and factors which stabilize and enhance these labile pigments were studied in this thesis. Berry anthocyanin colors were successfully improved by phenolic acid and natural plant extract addition. The results obtained contribute to the understanding of the chemical behavior of anthocyanins. The color quality of black currant wine was improved by the addition of crowberry juice...
