The contents of pyruvate in the sample were determined according to the methods of Lin et al. (1995 ). Protein was removed from the samples by TCA precipitation, and in the resulting sample, pyruvate reacted with 2,4-nitrophenylhydrazine. The product turned red in the presence of an alkali solution, and the intensity of the color change was measured by a spectrophotometer. A standard curve for calibration was obtained using sodium pyruvate as a reagent with a gradient of concentrations of pyruvic acid. Absorbance values were obtained to generate a standard curve to calculate the pyruvate concentration.
For glutathione (GSH), roots were ground in liquid nitrogen and homogenized in 1 mL 5% (w/v) m-phosphoric acid containing 1 mM diethylene triamine pentaacetic acid (DTPA) and 6.7% (w/v) sulfosalicylic acid. Root extracts were centrifuged at 12,000 × g for 15 min at 4°C. GSH contents were determined according to the methods of Kortt and Liu (1973 (link)) and Ellman (1959 (link)) with some modifications.
The ascorbic acid (AsA) content was determined according to Egea et al. (2007 (link)) with slight modifications. Ginseng roots were ground in an ice bath with 10 mL 5% metaphosphoric acid stored at 4°C, and then the final mix was homogenized by vortex. The final solution was maintained on the ice bath, in darkness, for 30 min and then centrifuged at 20,000 × g for 25 min at 4°C. Ascorbate was spectrophotometrically detected by measuring absorbance at 254 nm with a UV detector. For quantification of the compound, a calibration curve in the range of 10–100 mg kg−1 was prepared from standard ascorbic acid. Results were expressed as mg 100 g−1 FW.
Root extracts were centrifuged at 12,000 × g for 15 min at 4°C. The extraction and determination of ginsenosides was performed following the method of Yu et al. (2002 (link)).

Diet Cookies
Flour (50.0%), margarine (30.0%) fructose (10.0%), maltitol (8.0%), whole milk (1.0%), salt (0.2%), baking powder (0.15%), vanillin (0.1%) and different glucosyl Stevia compositions (0.03%) were kneaded well in dough-mixing machine. The obtained dough was molded and baked in oven at 200° C. for 15 minutes. Glucosyl Stevia compositions were by represented by Samples 1a, 2a, and 3, obtained according to EXAMPLES 3, 4, and 5, respectively; with Sample 4 being a commercial β-amylase treated product (containing only mono- and di-α-1,4-glucosyl-derivatives of steviol glycosides).
The sensory properties were evaluated by 20 panelists. The best results were obtained in samples prepared by high purity short-chain glucosyl Stevia compositions (containing four or less α-1,4-glucosyl residues) derivatives (Samples 1a and 2a). The panelists noted rounded and complete flavor profile and mouthfeel in cookies prepared with Samples 1a and 2a.

The Bli03644, abrB1, yvzC and abh genes were inactivated by insertion of antibiotic marker in a Bra7 strain producing a heterologous α-amylase (i.e., the heterologous P. curdlanolyticus α-amylase disclosed in PCT Publication No. WO2014/164834), wherein the heterologous α-amylase production was determined in the four single knock-out strains (ΔBLi03644, ΔabrB1, ΔyvzC and Δabh) and compared to the parental (control) strain as described in Example 2. For example, as presented in

Rhizopus oryzae (RO) lipase displayed far greater activity toward DHA and ARA triglycerides than porcine pancreatin (Zenpep®), which contains a mixture of pancreatic lipases, proteases, and amylases. 1.4 mL of infant formula was mixed with 100 uL of lipase (either pancreatin or RO lipase) and 100 uL each of triglycerides of DHA and ARA. Reactions were incubated at 37° C. for 15 minutes. Samples were taken at time points 0, 1, 2, 4, 6, 8, 10, and 15 minutes and analyzed by RP-HPLC for DHA and ARA. DHA (
