Optimization Of Enzymatic Transformation Of2-O-Α-D-Glucopyranosyl-L-Ascorbic Acid, Huang Liping, Hao Jianhua, Wang Wei, Sun Jingjing, Liu Junzhong

Food and Machinery

2-O-α-D-glucopyranosyl L-ascorbic acid(AA-2G) was transformed by marine microorganism cyclodextrin glucanotrans-ferase (CGTase) using L-ascorbic acid and β-cyclodextrin(β-CD) as substrate. The qualitative and quantitative analyses of AA-2G were undertaken by LC-MS and HPLC. On the basis of single factor experiment Plackett-Burman design was carried out to determine three main effective factors (pH, substrate concentration, enzyme concentration). Then Box-Behnken design using three factors and three levels was applied to optimize synthesis conditions of AA-2G. The results indicated that the optimum conditions were pH 9.07, enzyme concentration 90.78 U/g·β-CD, substrate concentration 56.81 g/L, the ratio of substrate 1∶1(volume ratio), reacting for 24 h, at …

Low Temperature Drying On Eating And Flavor Quality Of Infant Formula Noodle, Liu Ting, Gao Wenming, Xie Lan, Zhu Hong, Luo Chen, Yi Cuiping

Food and Machinery

Changes of water content, whiteness value, texture characteristics, cooking loss and flavor of the infant noodles dried at 25～40 ℃ for 4～7 h were studied. The results showed that with the time and drying temperature increasing, the moisture content decreased. The change of drying conditions had no significant effect on the cooking loss rate and flavor of noodles (P＞0.05), while the whiteness value of noodles was affected more obvious (P＜0.05). However the whiteness value was not affected under the drying condition of 25～30 ℃ for 5 h. The texture quality of noodles was affected by drying, and the elasticity decreases, …

Do We Need More Futures Contracts In Commodity Markets?, Fabio Mattos

Cornhusker Economics

In the last couple of months, there has been news about a new futures contract for soybeans. The Financial Times and Reuters, among others, reported that the CME Group, the world’s largest futures exchange, is considering launching a futures contract based on Brazilian soybeans. The discussion seems to have started after trade issues between the United States and China resulted in a 25 percentage-point tariff on U.S. soybeans exported to China. As Chinese buyers try to avoid the tariff by purchasing grain from other suppliers, notably Brazil, a new price dynamics between U.S. and Brazilian soybeans could be emerging. This …

Profitability Of Developing Beef Heifers On Stockpiled Winter Forages, Zachary David Mcfarlane, Chris Boyer, J. Travis Mulliniks

Journal of Applied Farm Economics

We estimate the profitability of developing heifers on one stockpiled cool-season grass and two stockpiled warm-season grasses during the winter months by comparing distributions of net present value (NPV) over an 11-year useful life. Furthermore, distributions of payback period and the break-even price for each calf over the heifer’s production life were generated for each forage species. These results are compared across forages as well as to a simulated drylot system for heifer development. Data comes from a grazing experiment in Tennessee, where heifers grazed big bluestem and Indian grass combination (BBIG), switchgrass (SW), or endophyte-infected tall fescue (TF) pastures. …

Comparison Of Space-Plant Versus Sward Plot Selection In Thickspike Wheatgrass (Elymus Lanceolatus), Joseph G. Robins, Kevin B. Jensen

Forage and Range Research Laboratory Publications

Thickspike wheatgrass (Elymus lanceolatus [Scribn. & J.G. Sm.] Gould) is an important native perennial grass species used for rangeland revegetation in North America. Plant breeding efforts relying on space‐plant evaluations have resulted in limited improvement in this species. The purpose of this study was to characterize the performance of thickspike wheatgrass half‐sib families under space‐plant and sward plot evaluations, estimate the correlation between measured traits in both evaluation settings, and determine the validity of selecting thickspike wheatgrass for rangeland revegetation in the nontarget environment space‐plant plots. The study included 50 thickspike wheatgrass half‐sib families and five commercial cultivars and experimental …

Phylogeny And Population Genetic Analyses Reveals Cryptic Speciation In The Bombus Fervidus Species Complex (Hymenoptera: Apidae), Jonathan B. Koch, Juanita Rodriguez, James P. Pitts, James P. Strange

Ecology Center Publications

Bumble bees (Bombus Latrielle) are significant pollinators of flowering plants due to their large body size, abundant setae, and generalist foraging strategies. However, shared setal coloration patterns among closely and distantly related bumble bee species makes identification notoriously difficult. The advent of molecular genetic techniques has increased our understanding of bumble bee evolution and taxonomy, and enables effective conservation policy and management. Individuals belonging to the North American Bombus fervidus species-complex (SC) are homogenous in body structure but exhibit significant body color phenotype variation across their geographic distribution. Given the uncertainty of the genealogical boundaries within the SC, some …

The National Resources and Conservation Service (NRCS) has developed the Mississippi River Basin Initiative which includes Arkansas as one of 13 states that is participating in this initiative. To date, Arkansas is known as the number one producer of the nation’s rice, bait fish, sport fish, and feeder fish, number two in broiler production, number three in catfish and number six …

The Local Food System Vitality Index: A Pilot Analysis To Demonstrate A Process For Measuring System Performance And Development, Jairus J. Rossi, Timothy A. Woods, Alison F. Davis

Agricultural Economics Faculty Publications

Identifying successful development priorities for local food systems (LFSs) is a challenge for pro­ducers, LFS advocates, Extension agents, and policymakers. Consumer perceptions and prefer­ences regarding what constitutes an active, healthy, and vibrant LFS often differ within and between diverse communities. Producers, development entities, and others would benefit from rapid assessment processes that provide detailed information on consumer preferences and potential market opportunities within their LFS.

In this paper, we introduce the analytic possi­bilities of our Local Food System Vitality Index (LFSVI). Using data collected from a pilot survey in Lexington, Kentucky, we rapidly assess the per­formance of 20 different components …

Utilizing Municipal Compost And Equine Stall Waste As Potential Economic Alternatives In An In-Ground Pot-In-Pot Production System, Ashley Robert, Alyx Shultz

Posters-at-the-Capitol

For Western Kentucky farmers, one viable income source could be a pot-in-pot nursery production. One of the highest costs of production in this system was the planting media that the plants were grown in. Economical alternatives to high-priced, non-renewable peat-based mixes were important to consider. Unique to this region, were two renewable soil amendments that may help farmers to widen their profit margin in a pot-in-pot system. This research looked at the economic viability of locally sourced horse stall waste and municipal compost as soil amendments to a traditional bark and peat based mix. Initial cost projections were favorable for …
