In silico approaches, as well as the BIOPEP database, PeptideRanker database, Peptide Calculator database (Pepcalc), ToxinPred database, and AllerTop database, were employed to evaluate the potential of glycinin and conglycinin derived peptides as a potential source of bioactive peptides. These major protein precursors have been found as protein in okara as a soybean by-product. Furthermore, primary structure, biological potential, and physicochemical, sensory, and allergenic characteristics of the theoretically released antioxidant peptides were predicted in this research. Glycinin and α subunits of β-conglycinin were selected as potential precursors of bioactive peptides based on in silico analysis. The most notable among these are antioxidant peptides. First, the potential of protein precursors for releasing bioactive peptides was evaluated by determining the frequency of occu...

The effect of different egg white concentrations (3, 6, and 9%) and whipping time (2 min and 5 min) on the foam properties of pasta sauce, including foam density, foam expansion, foam viscosity, water activity, morphological and drying behaviour, were investigated. The foamed sauce was dried in a batch-type thin-layer dryer at constant conditions (temperature of 60 °C). Six thin-layer drying models were employed to determine the drying kinetics of the pasta sauce. The results showed that an increase in the egg white concentration and a decrease in the whipping time produced a foamed sauce with low foam density and viscosity and high foam expansion. The Wang and Singh model was the best model to describe the drying behaviour of foamed sauce. According to Fick's second law model, the effective moisture diffusivity of the pasta sauce ranged from 4.

The development of a rapid analytical method to detect calcium oxalate in Amorphophallus flour is required. This research was intended to evaluate the use of some analytical methods (FTIR, SEM-EDS, XRD, XRF, and titration methods) in calcium oxalate detection in Amorphophallus muelleri flour prepared from different treatments (soaking in water (W), solution of sodium bisulfite 1000 ppm (B), solution of sodium chloride salt 3% (S), solution of sodium bisulfite 1000 ppm and sodium chloride salt 3% (BS)). Results showed that the presence of oxalate in Amorphophallus flour can be detected in the FTIR spectra from the C=O group at a wavenumber of 1610 cm-1. SEM images confirmed that calcium oxalate in Amorphophallus flour existed as raphide crystals in which their quantity can be estimated by the EDS feature of SEM. The presence of calcium oxalate crystals in Amorphophallus flour can be differentiated from other salts present in the flour by XRD. XRF can be used as a rapid analytical tool to detect the presence of calcium oxalate in Amorphophallus flour. The potassium permanganate titration technique can be used as a reference method for other rapid analytical methods in detecting calcium oxalate in Amorphophallus flour.

The consumption of gluten-free products rises annually and, therefore, there is potential in the development of gluten-free products. Most of the non-gluten pasta products (NGP) contain a low amount of protein. In this study, NGP prepared from modified cassava flour (mocaf) (40%), rice flour (35%), and maize flour (25%), was supplemented with tempeh flour as a source of protein. In this research, NGP was prepared by extrusion. The cooked dough was extruded using a single screw extruder (screw diameter, 60 mm, locally manufactured by the Research Centre for Appropriate Technology-Indonesian Institute of Sciences, Subang, West Java Indonesia). The procedure of making NGP involved mixing all ingredients, steaming, extrusion, tempering, drying, and packaging. The effect of tempeh flour supplementation (0%, 2.5%, 5%, 7.5%, 10%, 12.5%, and 15% (w/w)) on the properties of NGP product was evalua...

Among methods available to prepare CWSS, heating starch in ethanol can be considered to be the simplest one. The unique features of CWSS are depending on its starch origin and degree of conversion; therefore, its application should be specific depending on the feature of CWSS. This review summarizes methods to produce CWSS, advantage of producing CWSS by heating starch in ethanol method, the most important features of CWSS that influence its applicability, and exploration on CWSS applications. We expect that this review will be beneficial for food industries that utilize modified starch as ingredient in their products as well as researchers who seek potential applications of CWSS.

Adulteration of online-marketed powdered pepper product by tapioca flour was investigated by employing the FTIR technique. Powdered pepper products sold in five online market of Indonesia were surveyed then the FTIR spectra of some pepper products representing different pepper product categories were examined. By using the linear correlation between the concentration of powdered pepper and the normalized absorbance intensity of FTIR then the relative purity of powdered pepper products was determined. Result showed that out of 15 pepper products, 3 powdered pepper products (sample C, D and M) were confirmed being added by other ingredients, however, they cannot be classified being adulterated since their label says that they contain ingredients other than pepper. One product (sample K) in the category of powdered pepper products having brand and their label says that it is made of ground pepper was suspected being adulterated in which its relative purity was 67.3%. Based on this result, FTIR can be used as a fast and reliable analytical method to detect adulteration of powdered pepper product by tapioca flour.

The effect of heating temperatures (60 °C, 80 °C, and 100 °C) on the structural and pasting properties of pre-gelatinized adlay flour was studied. Moreover, the sensory acceptability of instant porridge prepared from this flour was investigated. Results showed that the shapes of starch granules of pre-gelatinized adlay flour started to disappear at a temperature of 80 °C. However, the crystallinity of the flour gelatinized at 60 °C was higher than that of flours gelatinized at other temperatures. The treatment increased water absorption, water solubility, and swelling power of pre-gelatinized adlay flour. It changed the pasting properties of pre-gelatinized adlay flour and decreased the lightness of pre-gelatinized adlay flour. Overall, the panelists preferred the instant porridge made from pre-gelatinized adlay flour prepared from 100 °C

The impact of heating temperatures of 60, 80, and 100 °C (coded as ICF-60, ICF-80, and ICF-100) on the properties of instant cassava flour (ICF), including colour, morphological, and thermal properties, water absorption, and solubility indexes and pasting behaviour, were investigated. Results showed that ICF produced at higher temperatures exhibited lower lightness, higher redness, and yellowness values. ICF-60 and ICF-80 still displayed the granular forms and birefringence properties of native starches, while granules of ICF-100 were broken and partially lost their birefringence properties. Results of X-ray diffraction (XRD) technique and differential scanning calorimetry (DSC) analysis suggested that the amylopectin double helixes of crystalline regions within the structure of ICF orientated to more perfect conformation before they were disrupted at the highest heating temper...
