Organoleptic, physical and chemical tests of formulated feed for Panulirus homarus, enriched with spinach extract

Spinach extract contains moulting hormone (phytoecdysteroid) which functions as a skin moulting hormone and regulates physiological functions, such as: growth, metamorphosis and reproduction in arthropods. The purpose of this study was to evaluate the quality of formulated feed for Panulirus homarus enriched with spinach extract based on organoleptic, physical and chemical tests. Five treatments with different doses of spinach extract (0; 0.4; 0.5; 0.6 and 0.7 mg) were used in this study. The parameters observed were organoleptic, physical and chemical. Data analysis used the Kruskal Wallis test for organoleptic parameters, the ANOVA test for physical parameters and the descriptive test for chemical parameters. Kruskal Wallis's analysis showed that spinach extract had a significant effect on the aroma of the test feed (P0.05). The one-way ANOVA results showed that adding spinach extract to the artificial feed had a significant effect on breaking speed, solids disperse, hardness level, sinking speed, attractiveness and deliciousness (P
