Preparation,Separation And Amino Acid Sequence Analysis Of Corn Oligopeptides With Antialcoholism Activity, Ma Wei, Dai Jun, Chen Shangwei, Zhu Song

Food and Machinery

Corn oligopeptides(COP) were prepared via enzymatic hydrolysis of destarched corn proteins by Alcalase 2.4L. By investigated COP antialcoholism activity in vitro and in vivo, it is found that COP has highly antialcoholism activity. Meanwhile, the scavenging rate of blood alcohol concentration is positively correlated with the dose of COP. COP were separated by Sephadex G-15 gel chromatogram and RP—HPLC step by step, then fraction COPⅢ-17 was separated with highly antialcoholism activity. UPLC—Q—TOF—MS analysis showed that its amino acid sequence: P-Y-L-P-L-L-P-S.

Separation And Enrichment Of Polyphenols From Sunflower Kernel With Mcroporous Resin, Xu Dandan, Zhang Wenbin, Yang Ruijin, Zhao Wei, Hua Xiao

Food and Machinery

An efficient preparative separation and enrichment process of polyphenols from sunflower kernel extracted by acid solution has been developed in the present study. 3-O-caffeoylquinic acid (CQA), 4-O-CQA and 5-O-CQA were identified as the main polyphenols in crude extract. The adsorption capacity and desorption ratio for total polyphenols of nine macroporous resins had been evaluated and XDA-1 resin was found to be the most suitable resin for the separation of polyphenols. It was found that ultrafiltration as preliminary treatment could improve the purity of crude extract from 4% to 15%. After that, the extract was submitted to XDA-1 resin column. The …

Application Of Information Technology In Chinese Food Safety Management, Xiao Yumei, Xiao Fuqiang

Food and Machinery

The management of Chinese food safety is not optimistic right now. The mainly cause of this problem is the degree of food information in low procurement, production, circulation, and other aspects. Whether the government supervision departments or social forces are difficult to comprehensively collect and master the information related to food security. It can not form a timely and effective regulation. In the contrast, information technology is applied to the important link of the food safety management in the United States, the European Union and other developed countries or regions. The experiences of the developed countries should be taken as …

Profitability Vs. Feasibility And The Paradox Of Purchasing Farmland, Larry Van Tassell

Cornhusker Economics

A student came to my office not too long ago excited about the opportunity to purchase 80 acres of farmland close to his family抯 farm. His father offered to let him use the family machinery and equipment in exchange for labor. The student had properly worked his cost-and-return estimates for field corn and was excited that the undertaking looked like a profitable venture. So we took a look at the annual principal and interest payments that would be due over a 20-year and 30-year loan life given the price of the land and his available 25% down payment. Sadly, the …

Community Seed Banks: Origins, Evolution, And Prospects, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

As a survey of contemporary community-level seed banks, this is an excellent compilation and instructive guide. The first section provides an overview of how seed banks originated, their varied goals and activities, several contrasting forms of management, and how they organize and perform to meet these goals. An intriguing claim in the book is that the concept of “seed banks is only some three decades old,” while in fact the practice of saving, preserving, and exchanging seed within a community is probably as old as human communities themselves.

Organized seed banks often serve specific functions: preserving seeds, providing seed access …

Adding Genetically Distant Individuals To Training Populations Reduces Genomic Prediction Accuracy In Barley, Aaron Lorenz, Kevin P. Smith

Department of Agronomy and Horticulture: Faculty Publications

One of the most important factors affecting genomic prediction accuracy appears to be training population (TP) composition. The objective of this study was to evaluate the effect of genomic relationship on genomic prediction accuracy and determine if adding increasingly unrelated individuals to a TP can reduce prediction accuracy. To accomplish this, a population of barley (Hordeum vulgare L.) lines from the University of Minnesota (lines denoted as MN) and North Dakota State University (lines denoted as ND) breeding programs were used for model training. Predictions were validated using two independent sets of progenies derived from MN  MN crosses …

Switchgrass Germplasm Resources, Michael D. Casler, Kenneth P. Vogel, Melanie Harrison
