1. Physical and sensory characteristics of salty cereal bar with different binding agents
Abstract The purpose of this study was to evaluate different binding agents for the preparation of salty cereal bars and to characterize them regarding their physical and sensory parameters. Four formulations of cereal bars were developed using collagen, guar gum, xanthan gum and psyllium as binders, which were evaluated for instrumental color and texture. T

2. Gluten-free pasta: development of a new formulation based on rice and lupine bean flour (Lupinus Mutabilis) using a mixture-process design
Abstract Gluten-free pasta was developed by substituting rice flour (RF) with lupin flour (LF). The factors tested were the substitution of RF by LF (10g/100g -30g/100g), egg (8g/100g -30g/100g) and guar gum (0.15g/100g -1g/100g) using a mixture-process design. Seven response variables were measured. Luminosity, ash content, protein content, chrome, hue, wei

4. Improvement of quality and shelf-life of Sübye, a traditional beverage of Turkey
Abstract Sübye, a traditional beverage of Turkey, is produced from melon seeds, sugar, and water. The standard production protocol for Sübye beverage includes mixing minced rehydrated melon seed mass with sugar to obtain Sübye paste in the ratio of 1:1.125 (w/w), respectively, and mixing 25% of the paste with water. The total moisture, sugar, fat, protein

5. Stabilization of guava nectar with hydrocolloids and pectinases
Abstract The aim of this study was to stabilize guava nectar using hydrocolloids and/or enzymes, and evaluate the stability and the bioactive compounds content during storage. In general, there was a decrease in pH and an increase in titratable acidity and soluble solids of the nectars. During storage, it was observed that nectars with pectinase showed decr

6. Detection, purification and characterization of a lectin from freshwater green algae Spirogyra spp.
ABSTRACT Freshwater algae are rich sources of structurally biologically active metabolites, such as fatty acids, steroids, carotenoids and polysaccharides. Among these metabolites, lectins stand out. Lectins are proteins or glycoproteins of non-immune origin which bind to carbohydrates or glycoconjugates, without changing ligand structure. Many studies have

7. INCORPORATION AND RELEASE KINETICS OF ALPHA-BISABOLOL FROM PCL AND CHITOSAN/GUAR GUM MEMBRANES
Abstract Alpha-bisabolol, an anti-inflammatory and antioxidant compound extracted from candeia trees (Eremanthus erythropappus), was incorporated into hydrophobic polycaprolactone (PCL) and hydrophilic chitosan/guar gum (Ch-G) membranes aiming at the production of bioactive wound dressings. The incorporation efficiency achieved a maximum of ca. 18% (1 gram o

8. Influence of animal fat substitution by vegetal fat on Mortadella-type products formulated with different hydrocolloids
Meat has played a crucial role in human evolution and is an important component of a healthy and well-balanced diet on account of its nutritional properties, its high biological value as a source of protein, and the vitamins and minerals it supplies. We studied the effects of animal fat reduction and substitution by hydrogenated vegetal fat, sodium alginate

10. Low Density Polyethylene (LDPE) blends based on Poly(3-Hydroxi-Butyrate) (PHB) and Guar Gum (GG) biodegradable polymers
LDPE blends based on PHB and GG biodegradable polymers were prepared by melt mixing in a twin screw extruder. The mechanical properties of the materials were evaluated. Preliminary information about the biodegradation behavior of the specimens was obtained by visual observation of samples removed from the simulated soil in 90 days. The results indicated that

12. Preparation, characterization and properties of films obtained from cross-linked guar gum
In this study the viability of using guar gum to form films was investigated along with the effectiveness of the cross-linking process employing 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC) as the cross-linking agent. In addition, the cross-linked films were evaluated considering the water absorption, thermal stability and mechanical pr
