The invention relates to a method for determining the organoleptic quality of a protein-rich microalgal biomass composition, comprising the determination of the content of 11 volatile organic compounds, wherein the 11 volatile organic compounds are pentanal, hexanal, 1-octen-3-ol, 2-pentylfuran, octanal, 3,5-octadien-2-ol (or 3-octen-2-one), 3,5-octadien-2-one, nonanal, 2-no-nenal, (E,E)-2,4-nonadienal and hexanoic acid.

A method for measuring the thermal stability of succinic acid includes the following steps: 1) preparing a succinic acid crystal powder having less than 1% residual water content; 2) placing 10 g of the crystal powder in an oven at 220&#xb0; C. for 2 hours; 3) pulverizing and sieving the crystal powder processed in this way, such that the particle size distribution thereof is between 0 and 10%, and preferably between 4 and 6% for particles larger than 500 &#x3bc;m in size, between 20 and 40%, and preferably between 25 and 35% for particles between 200 and 500 &#x3bc;m in size, between 50 and 75% and preferably between 55 and 70% for particles smaller than 200 &#x3bc;m in size; and 4) measuring the color, in a spectrocolorimeter, of the pulverized and sieved powder and determining the average value of the yellow (index 'b').
