Development of a 3D scanning method to discriminate blocks of Octopus minor with surplus water gain

Abstract 3D scanning method was developed to differentiate Octopus minor blocks which had surplus water to increase weight of O. minor. Effects of soaking time (0.5, 1 and 3 h) and apparent density of O. minor were determined using the number of O. minor in a block (4, 5, 6, and 7). A 0.5, 1, and 3 h soaking time increased O. minor weight by 11.85, 16.02, and 24.53%, respectively. Apparent density of non-weight gained O. minor blocks was significantly higher than those of 3 h soaked samples (p
