Sweet Potato Flour

The research was aimed to obtain moisture sorption curve , moisture sorption isotherm models and obtain determine the water content monoleyer of fermented sweet potato flour with red yeast rice.The moisture sorption isotherm model used are GAB (Guggenheim Anderson deBoer), BET (Brunauer Emmet Teller) and Caurie.Meanwhile, the test of modelling accuray by MRD (Mean Relative Deviation). The results showed that the water sorption isotherm curve of sweet potato flour fermented with red yeast rice Sigmoid shaped the approach of type II. The precise mathematical models are models of GAB (Guggenheim Anderson deBoer) with a value of MRD at a temperature of 30 °C, 35 °C, 40 °C respectively at 4.41%, to 2.50%, 3.37%. Moisture content of the monolayer at temperature of 30 °C, 35 °C and 40 °C in GAB model was 7.34%, 6.57%, 16.09%, BET model was 2.09%, 1.05%, 4.26%, and Caurie model was 1.41%, 1.36%, 1.42%.DOI: http://dx.doi.org/10.15408/jkv.v0i0.4814

In this research, a novel polysaccharide-based bionanocomposite film was prepared via dispersion casting method. Nano-silicon dioxide (SiO2-N) was incorporated into soluble soybean polysaccharide (SSPS) at different concentrations (i.e., 0%, 1%, 3%, and 5% w/w dried SSPS). Mechanical (tensile strength, elongation at break, and Young’s modulus), physical (moisture content, water solubility, and moisture uptake), and barrier properties of bionanocomposite films were evaluated. Incorporation of 5% SiO2-N to SSPS matrix decreased water vapor permeability (WVP) from 7.96×10−11 to 4.75×10−11 g m−1 s−1 Pa−1 and oxygen permeability from 215 to 96 cm3 µm m−2 day−1 atm−1. Heat seal strength and mechanical properties of SSPS films were improved. Moisture sorption isotherm of SSPS films supported by SiO2-N was shifted to lower moisture content, and monolayer moisture content of the films decreased significantly (p<0.05). In summary, SiO2-N is a potential filler in SSPS-based films for packaging materials.

Moisture Sorption Isotherm

The perishable herb ginger (Zingiber officinale) possesses natural aroma and different biologically active components which are beneficial for our health. This can be dried for preservation in pick season for shelf-life increment. This study studied the analysis of the chemical composition, moisture sorption isotherm, dehydration kinetics of ginger for preservation. Air drying was carried out using a cabinet dryer at different temperatures and thickness. According to the sorption isotherm study, monolayer moisture content (MMC) is higher as per Guggenheim-Anderson-DeBoer (GAB) equation compared to the Brunauer-Emmett-Teller (BET) equation. Drying rate increased with the increase in temperature at constant thickness while the adverse result was found with the increase in thickness at a constant temperature. Then, powder-based drinks were prepared by using five different percentages of ginger. The preferences of consumers were measured by statistical analysis of the scores obtained from the response of organoleptic taste panel. The sample containing 1.84% ginger powder was considered the best in overall acceptability
