Study on the Determination of the Optimum Parameters for the Inversion Reaction
نویسنده
چکیده
This study aims to determine the optimum parameters for the invert sugar obtaining, using the acid hydrolysis at t oC. The inversion reaction has been applied to 3 samples of sugar solution of different concentration (P1: SU = 70%, P2: SU = 75%, P3: SU = 80%). For obtaining the invert sugar syrup, different inversion temperatures have been used (t1 = 80oC, t2 = 90oC, t3 = 100oC). The inversion has been done in the presence of the citric acid (c = 0.5 g citric acid / 100 ml solution). The invert sugar is used as a total or partial substitute of the glucose syrup in the confectionery manufacture. Added in the sucrose syrup, it contributes to increase the dry matter/substances content and prevents the binding molecules of sucrose together, so it has the role of anti-crystallization. Based on this study, we have determined the optimum parameters for the invert sugar obtaining, depending on the content in reducing substances of the samples after the inversion operation. As a conclusion, we have got the following results: The inversion process carried out with maximum efficiency for the following samples: sample P1 with a reducing matters content of 40.64% at the temperature of 80oC; sample P2 with a reducing matters content of 45.2% at the temperature of 90oC; sample P3 with a reducing matters content of 76.40% at the temperature of 100oC.

Objective(s): Nanoemulsions are a kind of emulsions that can be transparent, translucent (size range 50-200 nm) or “milky” (up to 500 nm). Nanoemulsions are adequatly effective for transfer of active component through skin which facilitate the entrance of the active component . The transparent nature of the system and lack of the thickener and fluidity are among advantages of nanoemulsion. Mate...

Introduction: The limited spatial resolution of the gamma camera hinders the absolute quantification of planar images of small structures. The imaged structures are affected by partial volume effects (PVEs), which can spread activity and lead to underestimation of the regional distribution. The use of optimum planar parameters reduces the impact of the limited spatial resolution of the gamma c...
