Emerging new technologies have attracted considerable interest for extraction of bioactive compounds from medicinal plants. Carbamate ionic liquids have shown great solubility towards organic compounds; they are considered as green solvents for extraction of bioactive compounds. In this study, N, N-dipropyl ammonium N′, N′-dipropylcarbamate (DPCARB) and N, N-diethyl ammonium N′, N′-diethycarbamate (DECARB) were synthesized using solid carbon dioxide and a secondary amine which were dipropyl amine and diethyl amine, respectively. The synthesized carbamate ionic liquids were used for the extraction of curcumin from turmeric. Curcumin extraction yield was investigated at different extraction temperatures (15, 25, 35, 45 °C) and times (1, 3, 6 and 8 h). Results showed that the maximum curcumin extraction yields were 3.86 and 3.18%, obtained using the synthesized DPCARB and DECARB at 25 °C and 3 h, respectively. Also, the purity of the extracted curcumin using DPCARB was 85%, as determined by HPLC analysis. Results showed that the carbamate ionic liquids resulted in high extraction yield at room temperature and relatively short extraction time. The high purity of the extracted curcumin verifies the high selectivity of carbamate ionic liquids toward curcumin compared to other organic compounds available in the turmeric structure.

In this research Dunalliela sp.M1 isolate was cultivated in open pound bio reactor. This isolate was harvested by electrocoagulation method from culture medium. The harvested biomass was dried and desalinated. Lipid extraction process was carried out by soxhelt method and the effect of extraction time (20- 40min), solvent type (Hexane or mixture of hexane-Isopropanol 3:2) and ultrasonic pre-treatment factors on amount of extracted lipid was evaluated. Test results showed that in soxhelt method the hexane and isopropanol solvents (3:2 ratio),during 40 minutes and by applying of ultrasonic pretreatment had the maximum lipid extraction (16.64%). According to statistics analysis increasing of extraction time had significant effect (p<0.05) on amount of microalgae lipid extraction. But increasing of extraction time with pure hexane, has not any effect on amount of extracted lipid.By applying ultrasonic pre-treatment, extracted oil using hexane and isopropanol (3:2) increased by 4%. Fatty acid profile of extracted oil from this strain of microalgae showed that 59 % was saturated fatty acid which palmitic acid (36.62%) and stearic acid (19.02%) form the main portion of the composition.

Electrohydrodynamic atomization has recently been introduced as a safe method for encapsulation of sensitive bioactive compounds. In this regard, the parameters affecting the size and morphology of particles, owing to their key role in the protection and controlled release of bioactive compounds, are of paramount importance. In this study the influence of whey protein concentrate (WPC), gum Arabic and skim milk concentration as well as the operating voltage on the size and morphology of electrosprayed particles was investigated and the experimental data were then used for simulation of the process using two feed-forward artificial neural networks: multilayer perceptron and radial basis function networks. These models along with different threshold functions were employed to predict the viscosity, surface tension, electrical conductivity of polymers solutions, and the size of particles. The results showed that multilayer perceptron network comprising a set of 5 inputs and a single hidden layer containing 4 neurons with hyperbolic tangent activation function which was trained by Levenberg-Marquardt (LM) learning algorithm at 1000 epochs predicted the desired outputs more accurately than the radial basis function network. The determination coefficients (R2) for particles size, viscosity, surface tension, and electrical conductivity of polymers solutions were found to be 0.958, 0.9991, 0.996 and 0.967, respectively. Examination of the sensitivity analysis diagram of the predicted values by multilayer perceptron neural network versus experimental data revealed random scattering of points in the close proximity of the regression line with a high determination coefficient which clearly verifies the high accuracy of the model in predicting the outputs. It should be noted that size of particles as well as viscosity and electrical conductivity of solutions significantly increased with the rise of polymers concentration (p < 0.05). The findings of this study may be of useful to predict the impact of the above-mentioned parameters on the physical properties of polymer solutions and the fabricated particles in order to select the most appropriate wall materiel based on the purpose of encapsulation of bioactive compounds.

The aim of this research was optimizing of the chlorophyll extraction by ultrasound method. A Central Composite Design with 6 repeats at the central point was employed to optimize the effect of the ultrasound power (10-100%), solvent to solid ratio (5-10 ml/g), temperature (30-70 °C ) and time (2-10 min) on the total chlorophyll and a* value. Results of optimization showed that a quadratic model with R2=0.922 was significant. The solvent to solid ratio was the most important parameter which positively affected the yield, although increasing the temperature of extraction significantly reduced the yield. Enhancing the ultrasound power considerably increased the yield of chlorophyll. The maximum yield of chlorophyll was obtained under power of 100%, temperature of 30.2 °C, time of 9.83 min and solvent to solid ratio of 9.99 (ml/g) which was 680.5 mg/100 g d.m. The comparison of conventional and ultrasound methods showed that the yield of chlorophyll extracted by conventional method (460.5 mg/100 g d.m.) was significantly lower than the amount (680.5 mg/100 g d.m.) extracted by ultrasound method. Therefore, the ultrasound method is an efficient method for extraction of chlorophyll.

Nanocrystalline cellulose (NCC) reinforced fish myofibrillar protein (FMP)-based nanocomposite film was prepared by solution casting. The NCC content in the matrix was varied from 2, 4 and 6% ((w/w) % dry matrix). It was found that the nanocomposite reinforced with 6 wt% NCC content exhibits the highest tensile strength which was increased by 49% compared to the control. The formation of percolated networks of cellulose nanocrystals within protein matrix resulted in improving the mechanical properties of nanocomposites. Incorporation of NCC also significantly improved water vapor permeability (WVP) of the nanocomposite showing a 33% decrease due to 6 wt% NCC loading. The moisture sorption and water solubility studies revealed that the addition of cellulose nanocrystals reduced the moisture affinity of FMP, which is very favorable for edible packaging applications. Molecular interactions between FMP and NCC were supported by Fourier Transform Infrared Spectroscopy. Investigation of DSC factors (Tg, Tc, Tm) shown that thermal stability of FMP-based nanocomposite films was improved after incorporation of NCC.

Nowadays, concern about egg quality is growing steadily. Freshness makes a major contribution to the quality of egg and egg products. In this regard, in order to achieve both high efficiency and high productivity, eggs’ quality assessment is necessary to enhance safety and quality assurance. Therefore, the aim of this study was to design and fabricate a system to determine the internal quality of eggs using of machine vision. For this purpose, 210 eggs for 30 days were storted at room temperature and humidity in a completely randomized design and some quality parameters of eggs were measured (e.g. total weight of egg, yolk, albumen and eggshell weight, strength and thickness of the eggshell, Haugh unit as destructive parameters and air cell area, and area index (D) as non-destructive parameters). According to statistical analysis total weight of egg, strength and thickness of the shell, yolk and shell weight and yolk color as egg quality parameters were not affected by the storage time (p>0.05). But, the air cell area and the parameter D as non-destructive parameters, was increased significantly at the level of 5%. The results showed Haugh unit was decreased from 9.28 to 2.04 as storage time increased (p<0.05). Classification accuracy using non-destructive data with Parzen method was calculated 84.17%. This shows the ability of the proposed system to classify fresh eggs from unfreash ones with high accuracy.

Nisin is a bacteriocin that loses its activity due to binding to the protein, fat and other in the food systems. By preparing a film based on the biopolymer can improve its performance. The objective of this research was to investigate the antimicrobial activity and quantity diffusion of different concentrations of nisin (100, 200 and 300 mg) from 4 percent corn zein film in phosphate buffer and evaluation of antimicrobial activity and quantity diffusion of nisin from different concentrations of corn zein films (2, 4, 6, 8 and 10) in the phosphate buffer. The antimicrobial activity of nisin diffusion from corn zein films was performed with evaluation of growth inhibition of Micrococcus luteus in culture media and its quantity was evaluated with high-performance liquid chromatography method. In the final stage modeling of nisin release kinetics performed via empirical Weibull model. According to results the antimicrobial activity of nisin was confirmed by formation of growth inhibition halo in agar. Quantity diffusion of nisin from 4 percent corn zein film significantly increased with increasing concentration of nisin. With increasing the concentrations of corn zein from 4 to 10% (W/V) the nisin diffusion from corn zein film 10%, four times decreased which related to increase kink in film and slower release of nisin. Kinetic modeling diffusion from films showed similar behavior Fick with excellent prediction (R2 >0.95). Therefore by using the corn zein edible coating containing nicin antimicrobial composition can increase the shelf life and quality of food.
