A fermented millet flour called “Ibyer” traditionally available in Nigeria is increasingly being enhanced with ginger powder, of which its quality characteristics to our best knowledge appears not yet reported. To supplement existing information, therefore, the microbiological (which involved bacteria and fungi counts), pasting (which involved peak viscosity, trough, breakdown, final viscosity, set back, peak time, and pasting temperature), proximate (which involved moisture, ash, crude fat, fiber, protein, as well as carbohydrates), and sensory (which involved appearance, aroma, mouth-feel, consistency, taste, and overall acceptability) properties of fermented millet “ibyer” beverage enhanced with ginger powder were investigated. The major experimental stages included assembly of millet flour and ginger powder, preparation of blend formulation, making of “ibyer” beverage blends, and laboratory analysis. The blend involved fermented millet flour (FMF) decreasing, and ginger powder (GP) increasing, by proportions. Results showed noticeable microbiological, pasting, proximate, and sensory differences between blend samples and control. Compared to control, the blend samples obtained reduced bacterial and fungal counts, with increased peak, trough, final, set back viscosities, peak time, and pasting temperature, as well as moisture, ash, crude fat, crude fiber, and crude protein contents, but yet, with decreased sensory appearance, aroma, mouthfeel, taste, and overall acceptability.

Discernible Difference

Optical/infrared observations of RV Tauri stars obtained at SAAO have allowed the natures of the dust shells around stars with infrared excess to be investigated. The data suggest that dust formation occurs sporadically and that some stars have multiple shells. There is no photometrically discernible difference between carbon- and oxygen-rich stars or their dust shells. There is some evidence that stars with higher metallicity have more dust.

AbstractRecent advances in high-angular resolution instruments (VLT and VLTI, ALMA) have enabled us to delve deep into the circumstellar envelopes of AGB stars from the optical to the sub-mm wavelengths, thus allowing us to study in detail the gas and dust formation zones (e.g., their geometry, chemistry and kinematics). This work focuses on four (4) C-rich AGB stars observed with a high-angular resolution technique in the near-infrared: a multi-wavelength tomographic study of the dusty layers of the circumstellar envelopes of these C-rich stars, i.e. the variations in the morphology and temperature distribution.

Product quality control is a prerequisite for ensuring safety, effectiveness, and stability. However, because of the different strain species and fermentation processes, there was a significant difference in quality. As a result, they should be clearly distinguished in clinical use. Among them, the fermentation process is critical to achieving consistent product quality. This study aims to introduce near-infrared spectroscopy analysis technology into the production process of fermented Cordyceps powder, including strain culture, strain passage, strain fermentation, strain filtration, strain drying, strain pulverizing, and strain mixing. First, high performance liquid chromatography (HPLC) was used to measure the total nucleosides content in the production process of 30 batches of fermented Cordyceps powder, including uracil, uridine, adenine, guanosine, adenosine, and the process stability and interbatch consistency were analyzed with traditional Chinese medicine (TCM) fingerprinting, followed by the near-infrared spectroscopy (NIRS) combined with partial least squares regression (PLSR) to establish a quantitative analysis model of total nucleosides for online process monitoring of fermented Cordyceps powder preparation products. The model parameters indicate that the established model with good robustness and high measurement precision. It further clarifies that the model can be used for online process monitoring of fermented Cordyceps powder preparation products.
