This study investigates an efficient method to extract collagen from the skins of sea bass. The ultrasonic treatment (20 kHz with amplitude of 20–80 %) was applied to fish skin for 24 h after the addition of 0.01, 0.05, and 0.1 M acetic acid (1:200 sample/acetic acid, w/v). As a result, the rate (Ki) of the collagen yield increased depending on the amount of acid added, the duration of ultrasonic...
In this study we investigated the effects of ultrasonic wave treatment on the extraction yield of acid-soluble collagen from sea bass skins. Two extraction methods were compared: a 24 h acid treatment using 0.5 M acetic acid (1:200 sample/acid, w/v) and an extraction using ultrasonic treatment after the addition of a 0.5 M acetic acid solution. The results indicated that the extraction yield of collagen...
