A study was carried out to produce chocolates from coconut variants viz, coconut oil, coconut cream and coconut milk as a substitute for cocoa butter. The chocolate prepared with 40% cocoa butter was taken as control. Cocoa butter substituted at the levels of 10%, 20% and 30 % by coconut oil, coconut cream and coconut milk respectively were optimized based on the consumer acceptance. The fatty acid profile of the developed chocolate novelties were analysed using GC-MS and the lauric acid content was elevated to 1.92 %, 1.04 % and 1.17% in coconut oil, coconut cream and coconut milk chocolates respectively from 0.02 % in control. The thermal behavior of the developed chocolate novelties were analyzed by using Differential Scanning Calorimetry which exhibited harmonious distinct endothermic transitions between 28oC and 53oC. The developed chocolate novelties exhibited stable melting ranges in comparison with control.

A study was carried out to produce chocolates from coconut variants viz, coconut oil, coconut cream and coconut milk as a substitute for cocoa butter. The chocolate prepared with 40% cocoa butter was taken as control. The preliminary trials were conducted with different composition of ingredients for the optimization of the level of substitution of coconut variants. Cocoa butter substituted at the levels of 10 %, 20 % and 30 % by coconut oil, coconut cream and coconut milk respectively were optimized based on the consumer acceptance. The raw materials used in the fabrication of chocolate were subjected to analysed for Peroxide value (PV), Acid Value (AV) and Free Fatty Acid (FFA) content and were found to have desirable oxidative stability.

Objective: The main objective of the present work was to prepare and evaluate creams of celecoxib inclusions which are nonsteroidal anti-inflammatory drug to treat psoriatic arthritis. Methods: Celecoxib inclusions were prepared using β-cyclodextrin to increase the solubility. These inclusions were incorporated in creams. Cocoa butter, triethanolamine, stearic acid, methylparaben, gum acacia, and coconut oil were used in cream preparation. Fourier transform infrared and differential scanning calorimetry studies were carried out for pure celecoxib and inclusions. Viscosity, pH, homogeneity, and type of emulsion under dye test were evaluation parameters done for creams. Results: All the results obtained were within the limits and confirmed increased solubility of celecoxib inclusions. Conclusion: From the results obtained, increase in solubility of celecoxib drug was confirmed by forming inclusions using β-CD as polymer.

Aim: The work’s aim was the preparation and characterization of a hydrogel based on gelatin and glycerine, useful for site-specific release of benzydamine, an anti-inflammatory drug, able to attenuate the inflammatory process typical of the vaginal infection. Objective: The obtained hydrogel has been characterized by Electronic Scanning Microscopy (SEM) and Differential Scanning Calorimetry (DSC). In addition, due to the precursor properties, the hydrogel exhibits a relevant mucoadhesive activity. Methods: The swelling degree was evaluated at two different pHs and at defined time intervals. In particular, phosphate buffers were used at pH 6.6, in order to mimic the typical conditions of infectious diseases at the vaginal level, particularly for HIV-seropositive pregnant women, and pH 4.6, to simulate the physiological environment. Results: The obtained results revealed that the hydrogel swells up well at both pHs. Conclusion: Release studies conducted at both pathological and physiological pHs have shown that benzydamine is released at the level of the vaginal mucosa in a slow and gradual manner. These data support the hypothesis of the hydrogel use for the site-specific release of benzydamine in the vaginal mucosa.

The possibilities of applications of vibrational spectroscopy techniques (Raman spectroscopy) in the analysis and characterization of polymers are more and more used and accurate. In this paper, our purpose is to characterize Low Density Poly(Ethylene) (LDPE) grades by Raman spectroscopy and in particular with CH2 Raman vibration modes. With temperature measurements, we determine different amorphous and crystalline Raman assignments. From these results and on the basis of the evolution of CH2 bending Raman vibration modes, we develop a phenomenological model in correlation with Differential Scanning Calorimetry and in particular with crystalline lamella thickness determination.
