Drying and extraction of astaxanthin from pink shrimp waste (Farfantepenaeus subtilis): the applicability of spouted beds

Abstract

On this study, the spouted bed drying technique was used to obtain powder from shrimp wastes, with high quality for subsequent extraction of astaxanthin using vegetable oil, as alternative to organic solvents. Shrimp waste paste was dried in three inlet air temperatures (70, 80 and 90 °C), and air velocity used in the experiments was 100% over minimum spouting velocity. The minimum spouting, the velocities were 1.23, 1.33 and 1.39 m/s, for temperatures of 90, 100 and 110 °C respectively. The powder obtained in this work shows properties comparable to of the commercial products, indicating that the spouted bed is an alternative technique to obtain powdered products with quality good, at low cost and suitable for subsequent extraction of astaxanthin. The extractions of astaxanthin from shrimp waste were performed using palm olein at three different temperatures (50, 60, and 70 °C). At these conditions, maximum extraction of astaxanthin was 29.814µg/g of dried waste. The extraction kinetics were modeled using a simplified mass transfer kinetic model which showed a good agreement (0.9685<r 2 <0.9912), between the experimental and calculated data.

A comparative study on astaxanthin recovery from shrimp wastes using lactic fermentation and green solvents:an applied model on minced Tilapia

“…Lactic fermentation also solubilizes vesicles of the shrimp exoskeleton that are composed of calcium salts and contain large amounts of astaxanthin (Arancibia et al, 2014). An important issue in the recovery of astaxanthin from shrimp shells is the initial water content (Silva et al, 2018). Thus, the superiority of the recovering yield from solid-state cultures over submerged ones as shown in Table 1 could be attributed to the extraction efficiency, not to the fermentation process itself.…”

Ultrasonic-Assisted Extraction of Astaxanthin from Shrimp By-Products Using Vegetable Oils

“…Shrimp ( Penaeus longirostris ) by-products (head, shell, and tail) were obtained from a local fish market (Myrina, Lemnos), washed with distilled water, and then dried using a food dryer (24 h at 70 °C) as previously reported [ 45 ]. Dry shrimp by-product samples were processed for one minute in a laboratory grinder IKA A 10 basic (IKA Works, Wilmington, DE, USA) in order to produce a sample of fine powder.…”
