“…Lysine content is of particular importance because of its reactivity with the genipin, the natural crosslinking agent used in this study (Butler et al 2003;Nickerson et al 2006a, b;Maji and Hussain 2009). Lysine contents for the CPI, FPI, LPI and SPI products were found to be~6.3 %,~6.0 %,~6.8 % and~5.7 % respectively.…”

The physicochemical and emulsifying properties of legume protein isolates prepared from chickpea (CPI), faba bean (FPI), lentil (LPI) and soy (SPI) were investigated in the presence and absence of genipin. Solubility was highest for CPI (~94 %), followed by LPI (~90 %), FPI (~85 %) and SPI (~50 %). Surface characteristics revealed similar zeta potentials (~−47 mV) for CPI, LPI and FPI, but lower for SPI (~− 44 mV). Contrastingly, surface hydrophobicity was greatest for CPI (~137 arbitrary units, AU), followed by SPI/LPI (~70 AU) and FPI (~24 AU). A significant (from 16.73 tõ 8.42 mN/m) reduction in interfacial tension was observed in canola oil-water mixtures in the presence of non-crosslinked legume protein isolates. The extent of legume protein isolategenipin crosslinking was found to be similar for all isolates. Overall, creaming stability increased in the presence of genipin, with maximum stability observed for SPI (65 %), followed by FPI (61 %), LPI (56 %) and finally CPI (50 %).

“…The entrapment efficiency (%EE) was determined as per the methodology reported by Maji et al (14). An accurately weighed (10 mg) microspheres fabricated in different conditions (Table I) were added in a conical flask containing 10 ml of ethanol/phosphate buffer (1:9v/v) solution and continuously stirred at 700 rpm for 1 h. To avoid the oil evaporation due to high temperature and stirring, the flask was assembled on ice bath.…”

Encapsulation of Mentha Oil in Chitosan Polymer Matrix Alleviates Skin Irritation

et al. 2015

Abstract. Mentha spicata L. var. viridis oil (MVO) is a potent antifungal agent, but its application in the topical treatment is limited due to its irritancy and volatility. It was aimed to develop more efficient, chitosan-incrusted MVO microspheres with reduced volatility and lesser irritancy and to dispense it in the form of ointment. Simple coacervation technique was employed to microencapsulate MVO in chitosan matrix. Morphological properties and polymer cross-linking were characterized by scanning electron microscopy and differential scanning calorimetry, respectively. Optimization was carried out on the basis of entrapment efficiency (EE) using response surface methodology. Well-designed microspheres having smooth surface and spherical shape were observed. EE (81.20%) of optimum batch (R21) was found at 1.62%w/v of cross-linker, 5.4:5 of MVO to chitosan ratio and at 1000 rpm. R21 showed 69.38±1.29% in vitro MVO release in 12 h and 96.92% retention of MVO in microspheres even after 8 week. Ointments of PEG 4000 and PEG 400 comprising MVO (F1) and R21 (F2) were developed separately. F2 showed comparatively broader zone of growth inhibition (13.33±1.76-18.67±0.88 mm) and less irritancy (PII 0.5833, irritation barely perceptible) than that of F1. F2 was able to avoid the direct contact of mild irritant MVO with the skin and to reduce its rapid volatility. Controlled release of MVO helped in lengthening the duration of availability of MVO in agar media and hence improved its therapeutic efficacy. In conclusion, a stable and non-irritant formulation with improved therapeutic potential was developed.

“…The encapsulation efficiency (%), oil content (%) and oil loading (%) are generally calculated by using the calibration curve and the following formulae (Maji et al, 2007). In all the studied complexes, the oil loading (%), oil content (%), encapsulation efficiency (%) and release rate of oil were dependent on various factors like amount of oil, concentration of polymer, type and concentration of crosslinker.…”
