Binding effect of proline-rich-proteins (PRPs) on in vitro antimicrobial activity of the flavonoids BJM
Ansari,Jawaad Ahmed; Naz,Shahina; Tarar,Omer Mukhtar; Siddiqi,Rahmanullah; Haider,Muhammad Samee; Jamil,Khalid.
The interaction of the cyanidin, pelargonidin, catechin, myrecetin and kaempferol with casein and gelatin, as proline rich proteins (PRPs), was studied. The binding constants calculated for both flavonoid-casein and flavonoid-gelatin were fairly large (105–107 M−1) indicating strong interaction. Due to higher proline content in gelatin, the binding constants of flavonoid-gelatin (2.5 × 105–6.2 × 107M−1) were found to be higher than flavonoid-casein (1.2 × 105–5.0 × 107 M−1). All the flavonoids showed significant antibacterial activity against the tested strains. Significant loss in activity was observed due to the complexation with PRPs confirming that binding effectively reduced the concentration of the free flavonoids to be available for antibacterial...

Characterization of a Gelatin/Chitosan/Hyaluronan scaffold-polymer Electron. J. Biotechnol.
Enrione,Javier; Osorio,Fernando; López,Daniel; Weinstein-Oppenheimer,Caroline; Fuentes,Miguel A; Ceriani,Ricardo; Brown,Donald I; Albornoz,Fernando; Sánchez,Elizabeth; Villalobos,Patricio; Somoza,Rodrigo A; Young,Manuel E; Acevedo,Cristian A.
Gelatin, chitosan and hyaluronic acid are natural components used to prepare polymeric scaffold in tissue engineering. The physical properties of these materials confer an appropriate microenvironment for cells, which can be used as a regeneration system for skin and cartilage. In this work, we prepared and characterized a Gelatin/Chitosan/Hyaluronan lyophilized-polymer. Physical properties of lyophilized-polymer changed slightly with moisture, but when polymer was totally hydrated the elasticity changed significantly. Thermophysical characterisation indicated that temperatures higher than 30ºC could modify irreversibly the polymeric matrix probably due to protein denaturation. Besides, we used the polymer as scaffold to prepare a biosynthetic-skin,...

Silva,Thaiane Marques da; Barin,Juliano Smanioto; Lopes,Eduardo Jacob; Cichoski,Alexandre José; Flores,Erico Marlon de Moraes; Silva,Cristiane de Bona da; Menezes,Cristiano Ragagnin de.
ABSTRACT: Technique of complex coacervation was used to produce microcapsules of Lactobacillus acidophilus La-5 encapsulated in gelatin and gum arabic which were then freeze-drying. Microcapsules were characterized using scanning electron and optical microscopy, and resistance of probiotics was evaluated during release into a simulated gastrointestinal tract and storage at different temperatures. The complex coacervation process produced microcapsules with a high encapsulation efficiency (77.60% and 87.53%), ranging from 127.14-227.05 μm with uniform distribution. Microencapsulation was an efficient approach to achieve significant protection of probiotics against simulated gastrointestinal conditions compared with free cells. Encapsulation also improved...

Effect of hydrocolloids on the physicochemical characteristics of yellow mombin structured fruit Ciênc. Tecnol. Aliment.
Lins,Ana Carolina de Almeida; Cavalcanti,Diana Teresa de Barros; Azoubel,Patrícia Moreira; Mélo,Enayde de Almeida; Maciel,Maria Inês Sucupira.
The technology for the production of restructured fruit with high contents of fruit pulp using hydrocolloids as binding agents has not been fully developed. This study evaluated the effect of mixtures of sodium alginate, low methoxy pectin, and gelatin on the characteristics of yellow mombin (Spondias mombin L.) fruit gels. The results of the central composite design showed that the models obtained, except for those of water activity and soluble solids, were predictive. Gelatin was the most important factor affecting firmness, pH, and the color parameters of the structured fruit pulp.

Topçu,I.; Çivi,M.; Öztürk,T.; Keleş,G.T.; Çoban,S.; Yentür,E.A.; Okçu,G..
The effects of Ringer lactate, 6% hydroxyethyl starch (HES) (130/0.4) or 4% succinylated gelatin solutions on perioperative coagulability were measured by thromboelastography (TEG). Seventy-five patients (ASA I-III) who were to undergo major orthopedic procedures performed under epidural anesthesia were included in the study. Patients were randomly divided into three groups of 25 each for the administration of maintenance fluids: group RL (Ringer lactate), group HES (6% HES 130/0.4), and group JEL (4% gelofusine solution). Blood samples were obtained during the perioperative period before epidural anesthesia (t1, baseline), at the end of the surgery (t2), and 24 h after the operation (t3). TEG data, reaction time (R), coagulation time (K), angle value (α),...

Impact of stabilizers on the rheological properties of ice creams Ciênc. Tecnol. Aliment.
MILLIATTI,Mariana Carniell; LANNES,Suzana Caetano da Silva.
Abstract The effect of the food hydrocolloids Guar gum, Locust bean gum (LBG) and Gelatin, as well as their mixtures (even carrageenan was used in all formulations – 0.035%), was studied on the rheological characteristics of ice cream formulations. A frequency sweep test, at low temperature (-8 °C), was performed to evaluate the elastic (G’) and viscous (G”) modulus. The ice cream produced using Gelatin and blend of Gelatin and LBG (0.09 and 0.18%) presented higher values of G’, which is an indicative of the presence of ice crystals and greater rigidity. The thermo-oscillatory rheometry was used to correlate the rheological properties and the characteristic of the ice creams (creaminess, sensory, melting). A temperature sweep test, from -10 to 5 °C was...

Restructuring Passiflora cincinnata fruit pulp: influence of hydrocolloids Ciênc. Tecnol. Aliment.
Azoubel,Patrícia Moreira; Araújo,Ana Júlia de Brito; Oliveira,Silvana Belém de; Amorim,Mariana da Rocha.
This study evaluated the effect of mixtures of alginate, low methoxy pectin and gelatin on characteristics of P. cincinnata fruit gels, containing pulp with high soluble solids content (50 °Brix). The results of a central composite design showed that the models obtained, except for water activity and pH, were predictive. Gelatin was an important factor affecting firmness and colour parameters since higher concentrations of this hydrocolloid, combined with alginate concentrations greater than 1.3% and pectin quantity up to 1.26%, could be used to obtain clear yellow products with firmness greater that 1.2 kg.

The preservation effect and mechanism of gelatin on golden pompano (Trachinotus blochii) fillets during cold storage Ciênc. Tecnol. Aliment.
WEI,Peiyu; CAO,Jun; SHEN,Xuanri; LI,Chuan.
Abstract The effect of different concentrations of gelatin (0%, 2.5%, and 5%) and vacuum packaged on the preservation of golden pompano (Trachinotus blochii) fillets stored at 4 °C was studied over 14 days. The results suggested that both the gelatin groups (2.5% and 5%) showed a reduction in deterioration of colour, drip loss and texture compared to the control group (0%). In addition, the gelatin coating caused a slower reduction in the freshness indexes of the fish, such as total volatile base nitrogen (TVB-N), thiobarbituric acid reactive substances (TBARS), total viable counts and pH. During a certain storage period, the gelatin notably prevented the deterioration of the golden pompano fillet at 4 °C. The 5% gelatin group showed the best effect on...

Variation of Hydroxyapatite Content in Soft Gelatin Affects Mesenchymal Stem Cell Differentiation BABT
Kantawong,Fahsai; Tanum,Junijira; Wattanutchariya,Wassanai; Sooksaen,Pat.
Gelatin is a common material used in tissue engineering and hydroxyapatite (HA) has a composition and structure similar to natural bone mineral. HA is also used to increase the adhesion ability of scaffolds. The physical and mechanical properties of gelatin, together with the chemical properties of HA, can affect cell differentiation. The main purpose of this study is to investigate the gene expression of human mesenchymal stem cells (HMSCs) upon culturing on gelatin composite with HA. Low amounts of HA were introduced into the gelatin in order to modulate properties of gelatin. Three types of hydrogel were fabricated by glutaraldehyde crosslinking before lyophilization to produce the porous 3D structure: (1) pure gelatin, (2) 0.5 mg/ml HA in gelatin, and...
