[Liliana Florez-Palacios, Doctoral Student – Department of Crops, Soil and Environmental Sciences, University of Arkansas Division of Agriculture, standing in lab] .My name is Liliana Florez and I am a Ph.D. student at the University of Arkansas’ soybean breeding and genetics program.

Basically what I do is to investigate and study the sugar content in soybean seeds [Liliana studies the sugar content of Arkansas soybean seeds]. We are looking for soybean lines with high sucrose content and low stachyose content [Looking for seeds with high sucrose and low stachyose].

Sucrose content has to do with the taste of the foods and we want lines with the lowest stachyose content because the sugar is not digestible by monogastic animals. [High sucrose means a better tasting soybean]. When consumed in produces a lot of problems. Digestive problems such as flatulence and diarrhea. That’s why we are looking for those lines. [Finding low stachyose content is important because the stachyose sugar causes digestive problems in monogastic animals (animals with one stomach). Example of these animals are cats, pigs, horses, dogs, rabbits, and humans].

[Liliana shows a HPLC system. High Performance Liquid Chromatography System in the lav]. This is the HPLC system. High Performance Liquid Chromatography System and we use it to do sugar analysis. [Video shows a computer screen showing graphs and tables of what is found in the sample]. Basically what we do here is perform sugar extraction. And once we have the samples, we load them in the auto sampler. From the auto sampler they are going to be injected into the column and then we can identify the different peaks and each peak represents a different sugar. For example we have glucose, fructose, sucrose, which is one of the main ones we are looking at, then raffinose and stachyose.  So sucrose and stachyose are the ones that I’m studying.
