New infertility therapy effects of polysaccharides from Althaea officinalis leaf with emphasis on characterization, antioxidant and anti-pathogenic activity.

Characterization, antioxidant, anti-pathogenic and infertility therapy effects of polysaccharides from Althaea officinalis (marshmallow) leaf (AOLPS) were investigated. AOLPS was fractionated using ion-exchange chromatography, affording fractions of AOLPS-1, AOLPS-2, AOLPS-3 and AOLPS-4. The fractions were mainly composed of d-galactopyranose (α-(1 → 4)-glycosidic bond) with the average molecular weight of 1220 2240, 998 and 2670 Da, respectively which means it was a pectin-like polysaccharide.

Optimization of oxidative stability, color and sensory properties of uncured (nitrite-free) Asian hot dogs (Jigo) using response surface methodology (RSM).

This work investigated the effect of natural antioxidants (ascorbic acid (AA), α-tocopherol (TOC) and orange dietary fibre (ODF)) on oxidative stability, color and sensory properties in uncured hot dogs during chilled storage (3 ± 1 °C 4 weeks). A box-behnken design was employed for analysis of the responses (TBARS, peroxide value, pH, colour, taste and aroma) to obtain optimal conditions. Sausages containing TOC (20 mg/kg) and AA (0.

Optimum extraction of polysaccharides from motherwort leaf and its antioxidant and antimicrobial activities.

Box-Behnken design was employed to optimize the extraction conditions for polysaccharides from the leaves of motherwort (Leonurus cardiaca L.). Three independent variables including extraction temperature (60-100 °C), extraction time (60-120 min), and the ratio of water to raw material (20-60) were investigated.

Extraction, antioxidant and antilisterial activities of polysaccharides from the flower of viper's bugloss.

The objective of the present research was to investigate the effect of microwave-assisted extraction (MAE) conditions on the extraction yield, antioxidant properties and antilisterial activities of the polysaccharides from the flowers of viper's bugloss (Echium vulgare L.). The four extraction variables, time (40-100min), microwave power (200-800W), temperature (30-70°C), and the ratio of water to raw material (10-70), were optimized using response surface methodology.

Optimization of polysaccharides from Zagros oak leaf using RSM: antioxidant and antimicrobial activities.

Ultrasonic assisted-extraction technique was applied to extract the polysaccharide from Zagros oak (Quercus brantii Lindl). The effects of four independent factors (ultrasonic power (X1: 150-300 W), extraction temperature (X2: 50-90°C), extraction time (X3: 30-90 min), and the ratio of water to raw material (X4: 15-45)) on the extraction yield of polysaccharide from the leaves of Q. brantii Lindl (QBLP) were optimized using response surface methodology.

Influence of beet sugar, calcium lactate, and Staphylococcus xylosus (with nitrate reductase activity) on the chemical, microbiological, and sensorial properties of Persian uncured frankfurters.

Unlabelled: This study investigated the effects of beet sugar (BS), calcium lactate (CL), and Staphylococcus xylosus (SX) on the general characteristics of uncured frankfurters. Minimum residual nitrite was observed in samples with a high level of BS and S. xylosus (8log(10) l0 viable cfu/g) after 2 mo.
