Embodiment 1

[0070] The avenal alkaloid levels of the resulting soluble oat flour were measured using reverse phase HPLC. Briefly, dehulled grains were extracted, dried and resuspended into aliquots. Aliquots were analyzed by HPLC with a C-18 column using a diode array spectrophotometer detector with detection at 340 nm. Peaks were quantified by comparison to a standard curve of authentic avena avenum alkaloids. The results of this test are illustrated in Figure 1A and Figure 1B middle. It was also found that the soluble oat flour prepared according to the methods described herein had a higher avenantrine content than oat flour processed by extrusion (without enzymes) alone.

[0071] specifically, Figure 1A Depicts avena alkaloids 2c, avena alkaloids 2p, avena alkaloids 2f and total avenum alkaloids (2c+2p+2f )level. As used herein, "SoluOat 100" or "SoluOat 100 flour" (whether singular or plural) shall refer to 99.5% whole oat flour and 0.5% mixed tocopherols made according to the p...

Embodiment 2

[0088] SoluOat Flour and Whole Oat Flour are manufactured in a conventional roller mill to produce an average particle size of 150 microns. Apply SoluOat powder to various types of food and beverages. The applications include instant powder applications, dry ingredients in baking and yogurt processing, and ready-to-drink (RTD) beverage applications. A grainy texture was observed in some finished applications containing SoluOat. The particle size of the SoluOat powder is believed to be primarily responsible for the grainy texture observed. "SoluOat", "SoluOat flour", "SoluOat90" or "regular SoluOat" (whether singular or plural) as used herein shall mean 90% whole oat flour, 5% sugar, 4.5 % maltodextrin and 0.5% mixed tocopherols.

[0089] The ground SoluOat powder was micronized using a FluidEnergy Micro-Jet Series 8 mill (jet mill) fitted with a bag at the discharge to collect the ground (micronized) powder. A Brabender volumetric screw feeder with a 1" diameter helical sc...

Embodiment 3

[0112] Samples for RVA / viscosity testing were prepared by milling the samples to pass through a 60 mesh screen. A 3.44 gram sample was measured on a dry weight basis and transferred to a sample pan. Deionized water was added to the sample to bring the total weight to 29 grams.

Abstract

Producing soluble oat flour with an increased level of avenanthramides by using enzymes to precondition whole oat flour prior to extrusion.

Description

[0001] References to related applications [0002] This application claims priority to U.S. Serial No. 13 / 784,255 filed March 4, 2013, the entire contents of which are expressly incorporated herein by reference. field of invention [0003] The present invention generally relates to whole oat flour having a soluble component (hereinafter "soluble oat flour"). More specifically, the present invention relates to a method of making soluble oat flour with increased avenanthramide content. Background of the invention [0004] Due to its health benefits, oatmeal has been a staple of the human diet for many years. For example, various studies have shown that daily oatmeal consumption can help lower blood cholesterol, reduce the risk of heart disease, promote healthy blood flow, and maintain healthy blood pressure levels. Additionally, oatmeal has a high content of complex carbohydrates and fiber, which contribute to slow digestion and stable blood sugar levels. [0005] Oat alkal...
