“…The p-value indicates the interaction strength between each independent variable [25]. These results clearly show that the linear coefficients (A, B, C), the quadratic term coefficients (A 2 , B 2 ), and an interactive term coefficients (AB) are significant at small p values (p< 0.05).…”

An ultrasound-assisted extraction (UAE) method was developed for the extraction of Fe (III) from wet-process phosphoric acid with di (2-ethylhexyl) phosphoric acid (D2EHPA). The influences of UAE parameters, including ultrasonic power, extraction time, concentration of D2EHPA and extraction temperature, were systematically studied. The response surface methodology, a statistical technique, was used to obtain the optimal conditions and evaluate the significance of variables affecting the extraction efficiency of the UAE. It was found that ultrasound could markedly improve the extraction rate of Fe (III) with D2EHPA, the largest improvement is up to 7 times compared with the traditional solvent extraction method. However, the extraction equilibrium of the extraction system was not affected by ultrasound. It is believed that the cavitation effect of ultrasound, along with the increased interfacial surface area, contribute to the enhancement of the extraction rate.

Recently, intensive processing of marine resources has attracted considerable attention. In order to further utilize the byproducts of aquatic shellfish (Pinctada martensii meat) with high value, this study proposes a method of extracting zinc and taurine from P. martensii meat. Zinc was first extracted from P. martensii meat with an ultrasonic crusher, and then taurine was further extracted by ultrasonic-assisted water extraction from the remaining shellfish. After optimization, the biological zinc extraction rate reached 8.63%, and the taurine extraction rate reached 0.71%. Meanwhile, the parameters for cation exchange separation and taurine purification were optimized, in which the injection volume, pH value, and elution rate were set to 8.0 mL, 4.5, and 3.0 mL/min, respectively. Ultimately, the purity the extracted taurine reached 98.16%. This study provides a novel method for the extraction of biological zinc and taurine by deep processing of shellfish meat.

“…The absorption peaks of amides A, B, I, II, and III are the main features for determining the characteristics of collagen (Li, Liu, Gao, & Chen, ). It has been reported that the absorption peaks of amides A, B, I, II, and III appear at approximately 3,400, 3,000, 1700–1600, 1600–1500, and 1300–1200 cm −1 , respectively (Wang et al, ; Zhu et al, ). The FT‐IR absorption spectrum of collagen extracted from yak rumen smooth muscle is found at 3,293.18, 3,068.18, 1654.94, 1,540.58, and 1,236.58 cm −1 , which is consistent with the collagen characteristic.…”

This study reports an effective method using enzymatic methods to extract collagen from yak rumen smooth muscle. The enzymatic extraction methods were optimized by response surface methodology. Additionally, the properties of the extracted collagen were analyzed by Fourier transform infrared (FT‐IR) spectroscopy and mass spectrometry (MS). The results showed that the optimal conditions were as follows: the pepsin addition was 0.95%, the enzymatic hydrolysis time was 21 hr, and the solid‐to‐solvent ratio was 1:11. Under these conditions, the collagen extraction rate could reach 3.62/100 g. The results of FT‐IR revealed that the amide A, amide B, amide I, amide II, and amide III bands of the collagen appeared at 3,293.18, 3,068.18, 1654.94, 1,540.58, and 1,236.58 cm−1, respectively. The MS identified seven types of collagen, which were type I, type III, type IV, type V, type VI, type VIII, and type XII. The results demonstrated that the enzymatic method can extract collagen from yak rumen smooth muscle with a considerably high yield and can preserve the intact structure of the collagen.
