Hydrodynamically Balanced systems have wide development as they have achieved the parameters of modern drug delivery system, it is a type of system which owes very tremendous and curative benefits for the delivery of oral controlled release dosage forms and have wide properties in many aspects such as its main role is to maintain the effective concentration in the system for longer period of time. To reduce the gastric mucosal irritation due to the presence of synthetic polymers, being a natural polymer incorporation of Plantago ovate (Psyllium Husk) could ease out the mucosal irritation in the gastric region. Due to its properties such as a rate-controlling polymer possessing a very good quality of swelling and good gelling nature, and also incorporated as a matrix-forming agent basically in the modified release formulation. Locust bean gum can be used as sustained-release carriers and release modifiers for the delivery of drugs. It is a neutral plant galactomannan extracted from the seeds (kernels) of the carob tree Ceratonia siliqua L fabaceae. Nowadays it is focussing polymer and a lot of researchers are focussing on exploring the potential in topical drug delivery, colonic drug delivery, oral sustained drug delivery, ocular drug delivery, buccal drug delivery.

OBJECTIVE: the present work proposed to extract Locust Bean Gum (LBG) from Algerian carob fruits, evaluate physicochemical and rheological properties (solubility). It aimed also to develop different formulations of strawberry jams with a mixture of LBG and pectin in order to obtain a product with a high sensory acceptance. METHODS: the physicochemical characteristics of LBG were assessed. The impact of temperature on solubility was also studied. The physical and the sensory profile and acceptance of five Jams were evaluated. RESULTS: composition results revealed that LBG presented a high level of carbohydrate but low concentrations of fat and ash. The LBG was partially cold-water-soluble (∼62% at 25°C) and needed heating to reach a higher solubility value (∼89% at 80 °C). Overall, the sensorial acceptances decreased in jams J3 which was formulated with 100% pectin and commercial one (J5). The external preference map explained that most consumers were located to the right side of the map providing evidence that most samples appreciated were J4 and J2 (rate of 80–100%). CONCLUSION: In this investigation, the LBG was used successfully in the strawberry jam’s formulation.

Полисахариды являются многофункциональными пищевыми ингредиентами, применяемыми в различных типах пищевых продуктов. Особый интерес вызывает изучение роли полисахаридов в качестве потенциальных про- или антиоксидантов в составе пищевых эмульсий. Основным недостатком традиционных способов оценки развития окислительных процессов в эмульсиях является необходимость предварительной экстракции жировой фазы, что может сопровождаться искажением реальных значений показателей окисления. В данной работе влияние полисахаридов на окислительную стабильность эмульсий изучено при помощи реактора окислительной устойчивости Oxitest, который позволяет проводить прямое измерение потребления кислорода в процессе окисления липидов, тем самым исключая необходимость экстракции и повышая достоверность полученных данных. Проведен сравнительный анализ 6 различных полисахаридов (альгинат натрия, i-каррагинан, камедь рожкового дерева, пектин амидированный, пектин высокоэтерифицированный, картофельный крахмал) в составе пищевых эмульсий. Методами ИК-Фурье спектроскопии и дифференциально-сканирующей калориметрии охарактеризованы состав и свойства исходных полисахаридов. Изучена вязкость 0,5%-ных растворов полисахаридов при помощи метода ротационной вискозиметрии. В результате проведенного анализа полисахаридов выявлены и охарактеризованы основные отличия в колебательных спектрах поглощения функциональных групп. Методом дифференциально-сканирующей калориметрии определены энтальпии теплового эффекта отделения влаги и начала термической деградации полисахаридов. Проведен многомерный статистический анализ полученных данных, выявивший основные закономерности между структурой и свойствами полисахаридов в составе эмульсий. Наибольшую окислительную стабильность проявили эмульсии на основе камеди рожкового дерева и амидированного пектина. Polysaccharides are multifunctional food ingredients used in various types of food products. The role of polysaccharides as potential pro- or antioxidants in food emulsions is of particular interest is. The main drawback of traditional methods for assessing the development of oxidative processes in emulsions is the need for preliminary extraction of the fat phase, which may be accompanied by a distortion of the real values of oxidation indices. In this work, the effect of polysaccharides on the oxidative stability of emulsions was studied using the Oxitest oxidative stability reactor, which allows the direct measurement of oxygen consumption during lipid oxidation, thereby eliminating the need for extraction and increasing the reliability of the obtained data. Comparative analysis of 6 different polysaccharides (sodium alginate, i-carrageenan, locust bean gum, amidated pectin, highly esterified pectin, potato starch) in food emulsions was performed. The composition and properties of the initial polysaccharides were characterized by FTIR spectroscopy and differential scanning calorimetry methods. The viscosity of 0.5% solutions of polysaccharides was studied using the rotary viscometry method. The analysis of polysaccharides revealed and characterized the main differences in the vibrational absorption spectra of functional groups. The enthalpies of the thermal effect of moisture separation and the beginning of thermal degradation of polysaccharides were determined by differential scanning calorimetry. A multivariate statistical analysis of the obtained data revealed the main relations between the structure and properties of polysaccharides in emulsions. Emulsions based on locust bean gum and amidized pectin exhibited the highest oxidative stability.

Objective: The main aim of the present research was to develop an oral fast dissolving polymeric film (FDF) with good mechanical properties, faster disintegration and dissolution when placed on the tongue.Methods: Eletriptan hydrobromide is prescribed for the treatment of mild to a moderate migraine. The polymers selected for preparing films were Pullulan, Maltodextrin (MDX), Acacia, Sodium alginate (SA), Locust bean gum (LBG), Guar gum (GG), Xanthan gum (XG), Polyvinyl alcohol (PVA), Polyvinyl pyrrolidine (PVP), Hydroxyl propyl methyl cellulose (HPMC) E5, and HPMC E15. Twelve sets of films FN1–FN12 were prepared by solvent casting method with Pullulan and combination of Acacia, MDX, SA, LBG, GG, XG, PVA, PVP, HPMC E5 and HPMC E15. Five sets of films FS1–FS5 were prepared using synthetic polymers like PVA, PVP, HPMC E5 and HPMC E15.Results: From all the prepared polymer formulations, FN2, FN8, and FS3 were selected based on disintegration time, and drug release and amongst this three FN2 was optimised based on its disintegration time (D. T). The percent drug release of the optimised film was compared with the percent release of the pure drug.Conclusion: The optimised formulation had a D. T of 16 s and a percent drug release of 97.5% in 10 min in pH 6.8 phosphate buffer and 100.6% drug release in 10 min in 0.1N HCl.
