This study focuses on the effects of extrusion processing on tannin reduction and oil loss in flaxseed (Linum usitatissimum L.) meal. The ranges of processing variables selected using central composite design were: barrel exit temperature (BET) of 76.3–143.6C; screw speed (SS) of 59.6–160.5 rpm and feed rate (FR) of 26.4–93.6 kg/h. The experimental values of tannin reduction and oil loss obtained were from 42.9 to 77.2% and from 1.5 to 7.6%, respectively. Optimal operating conditions were established: BET (137.9C), SS (156.8 rpm) and FR (26.4 kg/h) for maximum (77.2%) reduction of tannins and minimum (3.7%) oil loss. Response variables were mainly dependent on BET, whereas significant reduction of tannins and oil loss was achieved in studied BET and SS combination of process parameters (P ≤ 0.05). The results of this study demonstrated that significant reduction of tannins with minimum oil loss in flaxseed meal can be achieved commercially using an extruder. Practical Applications The extrusion technology has been explored to reduce the toxic compounds in different oilseed meals and oil extraction for production of functional foods. However, the production of extruded oilseed meals with high content of lipids (>16%) is limited as the oil percolation creates problem to preserve extrudates and maintain the hygienic condition of extruder plant. This study suggested that there is an immense possibility to use single‐screw extrusion cooking for reduction of tannin content with minimum oil percolation during production of extruded flaxseed meal for commercial food or feed purposes.

“…The R 2 adj (adjusted determination coefficient), which is the correlation measure for testing the goodness-of-fit of the regression equation [26], was 0.9789, which indicated that only 2.11% of the total variations were not explained by the model. Meanwhile, a relatively lower value of coefficient of variation (CV = 1.10) showed better precision and reliability of the experiments carried out [27,28]. …”

In this work, pressurized liquid extraction (PLE) of three acetophenones (4-hydroxyacetophenone, baishouwubenzophenone, and 2,4-dihydroxyacetophenone) from Cynanchum bungei (ACB) were investigated. The optimal conditions for extraction of ACB were obtained using a Box-Behnken design, consisting of 17 experimental points, as follows: Ethanol (100%) as the extraction solvent at a temperature of 120 °C and an extraction pressure of 1500 psi, using one extraction cycle with a static extraction time of 17 min. The extracted samples were analyzed by high-performance liquid chromatography using an UV detector. Under this optimal condition, the experimental values agreed with the predicted values by analysis of variance. The ACB extraction yield with optimal PLE was higher than that obtained by soxhlet extraction and heat-reflux extraction methods. The results suggest that the PLE method provides a good alternative for acetophenone extraction.

“…It has been reported that RSM can be used to optimize complex processes used to extract compounds from plants. [222324252627] To our knowledge, there are no reports on the use of RSM to optimize extraction conditions for quercetin, rutin, and kaempferol in buckwheat. In this study, we have focused on establishing a rapid and convenient method for extracting and quantifying three of the flavonoids (quercetin, rutin, and kaempferol) present in F. tataricum .…”

Background:Buckwheat (Fagopyrum spp., Polygonaceae) is a widely planted food crop. Flavonoids, including quercetin, rutin, and kaempferol, are the main bioactive components in tartary buckwheat (Fagopyrum tataricum (L.) Gaertn). From the nutriological and pharmacological perspectives, flavonoids have great value in controlling blood glucose and blood pressure levels, and they also have antioxidant properties.Objective:To optimize the conditions for extraction of quercetin, rutin, and kaempferol from F. tataricum.Materials and Methods:A combination of ultrasound-assisted extraction (UAE) and response surface methodology (RSM) was used for flavonoid extraction and yield assessment. The RSM was based on a three-level, three-variable Box-Behnken design.Results:Flavonoids were optimally extracted from F. tataricum by using 72% methanol, at 60°C, for 21 minutes. Under these conditions, the obtained extraction yield of the total flavonoids was 3.94%.Conclusion:The results indicated that the UAE method was effective for extraction of flavonoids from tartary buckwheat.
