Effects of Drying Methods on the Chemical Composition of the Sea Cucumber Holothuria forskali

Abstract

The effects of artisanal and controlled oven drying methods on the biochemical composition of the body wall of the sea cucumber, Holothuria forskali were investigated. Five combinations of temperature (°C) and relative humidity (%) levels were tested (50°C, 20%, 60°C, 25%; 60°C, 15%, 60°C, 20% and 70°C, 20%). The results demonstrate that the treatment (60°C and 20%) yields an improvement of the nutritional quality of the initial product. Improvements were particularly noted in terms of the amount of total proteins and the polyunsaturated fatty acids level in the dry body wall of H. forskali.

The effect of different drying methods on chemical composition, fatty acid, and amino acid profiles of sea cucumber (Holothuria tubulosa Gmelin, 1791)

“…It was determined that amount of protein in raw sea cucumbers was 10.33% and amount of protein in dried samples with different drying methods was 56.12%–62.70%. Similar to the results we have obtained, Telahigue, Hajji, Imen, and Sahbi ( reported that the drying process increased protein content in dried samples compared to raw samples. The highest protein content was detected in FD samples.…”

The changes in chemical composition of Holothuria tubulosa (Gmelin, 1788) with ambient‐drying and oven‐drying methods

“…Telahigue et al. () indicated improvements in the total protein level in the body wall of H. forskali dried at different temperatures and humidity levels. Compared to each other, an increase in the protein contents was observed to be dependent on a decrease in the moisture content in these studies.…”

“…Telahigue et al. () indicated improvements in the PUFA level in the body wall of H. forskali dried at different temperatures and humidity levels. Bechtel et al.…”

“…Chang-Lee, Price and Lampila (1989) reported the protein content to be 61.70% in dried sea cucumbers. Telahigue et al (2014) indicated improvements in the total protein level in the body wall of H. forskali dried at different temperatures and humidity levels.…”

“…Many studies on holothuria have been carried out in other countries (Bechtel, Oliveira, Demir & Smiley, 2013;Chong, Pindi, Chye, Shaarani & Lee,2015;Duan, Zhang, Mujumdar & Wang, 2010;Omran, 2013;Pereira, Valentão, Teixeira & Andrade, 2013;Sicuro et al, 2012;Telahigue, Hajji, Imen, Sahbi & El Cafsi, 2014;Wen, Hu & Fan, 2010;Xu, Xu, Zhang, Peng & Yang, 2016), but there have been very few in Turkey (Aydın, 2016;Aydın, Sevgili, Tufan, Emre & Köse, 2011;Bilgin & İzci, 2016;Çaklı, Cadun, Kışla & Dinçer, 2004;Özer, Mol & Varlık, 2004).…”
