Natural pigments have raised a growing interest due to their extensive range of colors, innocuous and beneficial health effects. In this paper, the extraction process and stability of strawberry red pigment were studied. An orthogonal test [L16(4)4] was applied to get the best extraction conditions. Results showed that the optimum conditions were that the extraction temperature was 65C, the solid-liquid ratio was 1:5 (g/mL), the ratio of 1.5mol/L hydrochloride to 97.5% ethanol was 3:17 (mL/mL), and the extraction time was 4.5 hours. The effects of heat treatment, oxidant, sugar and preservatives on the stability of strawberry red pigment were also discussed. The stability of strawberry red pigment was found to be affected by high temperature, hydrogen peroxide, and potassium sorbate. This study is expected to provide a basis for further research, development, and utilization of strawberry red pigment.

Turmeric has a bioactive compound namely curcuminoid. It has many pharmacology effects such as anticancer, antidiabetic, antioxidant, hypolipidemic, anti-inflammatory, antimicrobial, antifertility, anti-venom, anti-coagulant, anti-HIV hepatoprotective, nephroprotective, and anticoagulant properties. To increase the economic value of turmeric, it is necessary to develop a hydrothermal extraction process of turmeric’s active compound. The advantages of hydrothermal extraction were inexpensive, abundant availability, high purity, non-toxic, and easy to handle. This research aims to study the effect of operating conditions : temperature (130-150oC), time (10-40 minutes) and solid:liquid ratio (1:10 and 1:12) on the bioactive compounds of turmeric extracted from hydrothermal extraction process. Generally, high extraction yield was obtained at higher extraction temperature (140 and 150oC). Under these conditions, with a lower solid : liquid ratio (1:10), high concentration of curcumin is produced. Further, a higher solid : liquid ratio will likely produce the opposite result, except when it operates at low extraction temperature. The high temperature of the pressurized liquid water can reduce the viscosity and surface tension of water so it will increase the diffusion rates and absorption. The higher the solid:liquid ratio, the greater the different concentration between interior and exterior cell, which promote the high efficiency of diffusion process.

Taxus mairei is an important source for industrial extraction of taxol in China. However, the standard and steps of extraction are currently not uniform, which seriously affects the taxol yield. In the present study, the influence of four factors (methanol concentration, solid-liquid ratio, ultrasonic extraction temperature, and ultrasonic extraction time) on the taxol yield was successively explored in T. mairei. A response surface methodology (RSM) was used to optimize the extraction process based on the single-factor experiments above. The optimal conditions were as follows: methanol concentration was 90%, solid-liquid ratio was 1:15 (g/mL), ultrasonic extraction temperature was 40 °C and ultrasonic extraction time was 60 min. Moreover, the twigs and needles from T. mairei with different tree ages were treated by the optimum extraction process, which further revealed temporal and spatial distribution of taxol in the reproducible tissues. Interestingly, the taxol content was relatively higher in needles of T. ‘Jinxishan’ (a cultivar from T. mairei with yellow aril, FY), but was less in FY twigs. The accumulation of taxol in twigs and leaves of females (with red aril, FR) was significantly higher than that of males (M); however, the content showed a decreasing trend with the increasing tree ages. Therefore, it is suitable to increase the proportion of female trees especially the FY leaves as raw materials for the industrial production of taxol from T. mairei, and the tree ages should be better controlled at 3–7 years.

Using Box-Behnken center composite design of three variables with three levels, the optimal extraction process for carotenoids from tamarillo fruits were determined by response surface methodology. The optimal extraction process was obtained as followed: solid-liquid ratio of 1:19.02(g/mL), extraction temperature of 44°C, and extraction time of 33.68 min. Under these conditions, the extraction of carotenoids content was 5.755[mg/100, similar to the theoretical prediction of 5.885[mg/100. This study confirms the efficiency of RSM as a simple and effective method and the great potential of tamarillo fruits as a health food and a resource of carotenoids.

Continuous Countercurrent Extraction

In this work, a backmixing-diffusion model was developed for continuous countercurrent extraction process. Various parameters/factors influenced the extraction were investigated for juice extraction. Important parameters/factors studied were solid to liquid ratio, solid retention time, extraction temperature, external resistance to mass transfer, size and shape of solid materials and degree of backmixing for solid and liquid phase. For juice extraction from pineapple, apple and pear, it was found that the backmixing-diffusion concept can be used through the whole range of operation time. The model could predict the concentration profile well for both unsteady state period and steady state one. The simulation was successful for juice extraction process.

Abstract Effective diffusion coefficient (D-value) is an important parameter for the extraction process. In this study, a cylindrical model to estimate the D-value of betanin extraction from red beet roots was developed. The influence of extraction temperature, pH, cylindrical thickness and type of acids on the D-value was also investigated. The optimal parameters of betanin extraction were 30°C, pH 4.0 adjusted with sulfurous acid or acetic acid. D-values under the above conditions were 18.95×10−11 m2/s and 17.87×10−11 m2/s, respectively. The result showed that D-value elevated with the increase of cylindrical thickness, which was consistent with earlier conclusion from spherical model. The modeling may be useful for the investigation into extraction process and practical application.

AbstractTea, from the old ages to the day, is widely consumed both for enjoyment and health care due to its positive effects. The consumption of these products is increasing day by day as a result of the clear presentation of the fact that tea contains high amount of antioxidant substances (such as phenolic compounds), which is important in prevention and treatment of diseases. Tea beverage is a very important source of polyphenols. In this study, phenolic content and antioxidant capacity of different tea species were calculated by modeling with experimental design method. In the experimental part, polyphenol content was determined using the Folin-Ciocalteu method. The total amount of phenolic substance content was examined by Box-Behnken design and response surface method on black tea, green tea and white tea on different extraction temperature, extraction time and solid / liquid ratio. Solid / liquid ratio was found to be the most important parameter in terms of polyphenol content extraction from different tea samples. The highest polyphenol amount (411.762 mg gallic acid / mL) was found in green tea. To the best of our knowledge, this is the first data presenting comparatively study the effect of extraction condition on amounts of phenolic compounds from different tea samples.
