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.

The consumption of edible products strongly recommends the regular hygiene of oral cavity. Various dental products of allopathic and herbal origin are used as dentifrices. The dentifrices are considered safe and effective in terms of cleansing effect of oral cavity and antimicrobial effect against microbes causing bad smell and diseases such as gingivitis, pyorrhea etc. These characteristics of preparations are basically related to physicochemical properties of ingredients present in their composition and some how on directions of their use. In the present study, the marketed allopathic dentifrices coded as Brand I and II and herbal tooth powders coded as Brand III and IV were selected to analyze the impact of physicochemical properties of incorporated ingredients on their cleansing efficiency. The physicochemical characteristics studied were pH, bulk volume, tapped volume, tapped density, bulk density, true density, porosity, flowability, compressibility, compactability, cohesiveness, dispersability, Carr’s index, Hausner’s ratio, water soluble content, alcohol soluble content, foaming index, particle rearrangement behaviour and particle rearrangement constant. The antimicrobial effect of these powders was studied against Staphylococcus sorbinus, Staphylococcus salivarius and Lactobacillus acidophilus. It was observed that some of the physicochemical properties of all powders were different from each other. Marked antimicrobial effect of tooth powders was observed against pathogens. In all preparations, remarkable foaming index was analyzed that was generally considered responsible for cleansing effect.

The study was carried out with the aim of developing gluten free cookies using rice-chickpea composite flour. Guar and locust bean gum were added to formulations at two test concentrations (0.5 and 1.0%). To study the impact of these hydrocolloids, pasting and rheometry of dough formulations was carried out. The cookies produced were subjected to colour, spread ratio, hardness and antioxidant analysis. Protein (7.56 g/100g), fat (1.78 g/100g), ash (1.25 g/100g) and carbohydrate (80.41 g/100g) content of composite flour varied significantly (p ≤ 0.05) from both rice and chickpea. Higher viscosity, viscoelasticity and antioxidant profile was shown by dough formulations with added gums. Control cookies prepared without gums showed the L*, a* and b* values of 54.62, 3.81 and 35.97, respectively. With the addition of guar and locust bean gum, colour of the cookies became lighter. Spread ratio and hardness of cookies with added gums was higher.

The present study was carried out to develop oral controlled release matrix tablets and three layer matrix tablets of highly water soluble diltiazem HCl using natural polymers Xanthan gum (XG), locust bean gum (LBG) and a mixture XG: LBG in 1:1 ratio as matrix forming agent, and anionic Sodium Carboxyl Methyl Cellulose as release retardant layer on the matrix core, Di calcium Phosphate (DCP) and Micro crystalline Cellulose (MCC) as fillers. Matrix core tablets were prepared with by granulation technique.The characterization of physical mixture of drug and excipeints was performed by infra red spectroscopy. The finding of the study indicated that the matrix tablets prolonged the release, but predominantly in a first order fashion, layering with SCMC granules on the matrix core, provided linear drug release with zero order kinetics. The influence of layers on matrix core and release rate was described by the peppas equation, model independent approach, Mean dissolution time (MDT) and dissolution efficiency (D.E 8%). The addition of SCMC layers on the matrix core could notably influence the dissolution behavior and mechanism of drug release. Increasing the quantity of layers caused decreased values of k and increased n value, in a linear relationship. MDT for matrix tablet (S6)  and three layer matrix tablets (S6L3) was found to be 5.16h and 11.97h, D.E 8% was 76.23% and 66.21% respectively.  These indicated that the release of drug is slower from the three layer matrix tablets. Type of fillers has a limited effect on the drug release mechanism from matrix tablets. Stability studies revealed that the formulation was stable at 45°±2°C and 75±5%RH. Hence natural polymer as matrix core and anionic polymer SCMC as retardant layer in the form of three layer matrix tablets provided the zero order release of highly water soluble Diltiazem HCl.

The widespread distribution of persistent organic pollutants (POPs) in landfill leachate is problematic due to their acute toxicity, carcinogenicity and genotoxicity effects, which could be detrimental to public health and ecological systems. The objective of this study was to evaluate the effective removal of POPs – namely, p-tert-Butylphenol and Pyridine, 3-(1-methyl-2-pyrrolidinyl)-, (S)- – from landfill leachate using locust bean gum (LBG), and in comparison with commonly used alum. The response surface methodology coupled with a Box–Behnken design was employed to optimize the operating factors for optimal POPs removal. A quadratic polynomial model was fitted into the data with the R2 values of 0.97 and 0.96 for the removal of p-tert-Butylphenol and Pyridine, 3-(1-methyl-2-pyrrolidinyl), (S)-, respectively. The physicochemical characteristics of the flocs produced by LBG and alum were evaluated with Fourier Transform Infrared (FTIR) spectroscopy and Scanning Electron Microscopy (SEM). The infrared spectra of LBG-treated floc were identical with LBG powder, but there was some variation in the peaks of the functional groups, signifying the chemical interactions between flocculants and pollutant particles resulting from POPs removal. The results showed that p-tert-Butylphenol and Pyridine, 3-(1-methyl-2-pyrrolidinyl)-, (S)- obtained 96% and 100% removal using 500 mg/L of LBG at pH 4. pH have a significant effect on POPs removal in leachate. It is estimated that treating one million gallons of leachate using alum (at 1 g/L dosage) would cost US$39, and using LBG (at 500 mg/L dosage) would cost US$2. LBG is eco-friendly, biodegradable and non-toxic and, hence, strongly recommended as an alternative to inorganic coagulants for the treatment of POPs in landfill leachate.

The article discusses methodological problems behind increasing the efficient transformation of law in a developed information society and assessing their impact on the processes of socioeconomic development of the state and society. Methods and technologies of analysis and management of the development of complex socioeconomic systems are considered. To solve methodological and practical problems of increasing the efficiency of legislative regulation in the context of digitalization, it is proposed to use the scenario analysis methodology, which provides an opportunity for intellectual support and assessment of the quality of preparation and implementation of decisions in the field of legislative activity. The approach proposed for solving the problems under consideration is based on advanced scenario analysis and modeling of the development processes of situations in the political-legal, sociopolitical, socioeconomind innovation-technological spheres. This will allow us to work out alternative options for the development of the law enforcement situation, for which, in general, information is incomplete and there is a high level of uncertainty in its development. The authors have formulated promising directions for future theoretical and applied research within the framework of the development of the methodology of scenario analysis of social and economic reality, as regulated by the rules of law.

In recent years, in addition to the basic tenets of teaching and research, commercialization and innovation have become core priorities in higher education (Friedman & Silberman, 2003; Etzkowitz, 2003; Rasmussen et al., 2006). Universities have the right ingredients to be natural technology transfer incubators with a high influx of innovators and the capability to create new ventures and have high potential to generate a high level of economic development. Commercialization allows the results of innovative research to be utilized through transformation into marketable products or ‘technology transfer’. Since the 1980s, Canadian universities have begun dedicating resources and effort to discover how to best harness the innovation arising out of university-based research for knowledge transfer and revenue generation through commercialization. This thesis focuses on specific university inputs that influence the volume of technology transferred to industry through various commercialization channels and the impact each factor may have considering the institution size. Through data verified primarily from the Association of University Technology Managers’ (AUTM) annual surveys of Canadian and American universities from 2011 to 2015, this study analyzes the effect of administrative characteristics on technology transfer at a university. While the results of the study do not provide much conclusive guidance on the reasons behind growth in university-industry technology transfer, they do suggest that there is some greater effect in large universities that leads to more technology transfer activity than in smaller universities.

Background: The galactomannans are water-soluble carbohydrates widely used in the food, pharmaceutical, biomedical, cosmetic, textile and paper industries. Recently, a need for an alternative industrial source of galactomannans has arisen; one possible source is Honey locust (Gleditsia triacanthos), which is abundant in Algeria. Objective: The main objective of this study was to determine the physicochemical and rheological properties of Water-Soluble Galactomannan (WSG) purified from the seeds of Algerian Honey locust (Gleditsia triacanthos L.). Methods: The galactomannan was purified from the seeds of Gleditsia triacanthos and was structurally characterized by chromatographic (HPAEC, HPSEC-RID-MALLS) and spectroscopic (FT-IR, 1H, 13C NMR) methods. Results: The Honey locust seed contains a high level of WSG (yield, 10%), and the molecular weight of its WSG was approximately 871.9 kDa. A highly viscous solution was obtained and had an intrinsic viscosity [η] of 7.14-7.25 dL/g and an optical activity [α]D of +38.7°. Chromatographic and spectroscopic analyses indicated the presence of β-D-mannopyranose and α-D-galactopyranose in the heteropolysaccharide at a molar ratio of 2.86:1. The linear backbone of its macromolecule has a central core composed of 4-linked β-mannose units, with branches of galactose, linked to the carbohydrate core through α(1-6) linkage. Conclusion: These results lead to the conclusion that galactomannan presents the desirable physicochemical characteristics suitable for applications in the pharmaceutical, cosmetic and food industries.
