and/or a microwave treatment. ### Claim 13 (depends on 11) The process according to claim 11, wherein the transformation comprises, after dehydration, grinding of said larvae in order to obtain said beetle powder. ### Claim 14 (depends on 2) The process according to claim 2, wherein the transformation is carried out on beetles in the larval or nymphal phase. ### Claim 15 (depends on 2) The process according to claim 2, wherein the transformation is carried out on larvae fractions obtained from chemical or mechanical extraction techniques. ### Claim 16 (depends on 2) The process according to claim 2, wherein the transformed larvae have a thickness of between 1 and 100 millimeters, preferably between 5 and 15 millimeters, preferably after grinding. ### Claim 17 (depends on 1) The process according to claim 1, wherein the ultraviolet radiation emitted by said at least one light source toward the beetle larvae during the light treatment is: UVB radiation and consists of electromagnetic radiation having a wavelength of between 280 nm and 320 nm; and/or UVA radiation and consists of electromagnetic radiation having a wavelength of between 320 nm and 400 nm. ### Claim 18 (depends on 1) The process according to claim 1, wherein, in the light treatment, the at least one light source is positioned at a specific distance from the beetle larvae between 1 and 100 centimeters, preferably between 5 and 20 centimeters. ### Claim 19 (depends on 1) The process according to claim 1, wherein said at least one light source has a radiation power of between 13 and 125 Watts, preferably between 20 and 50 Watts. ### Claim 20 (depends on 2) The process according to claim 2, wherein, during the light treatment, said at least one light source emits ultraviolet radiation toward the transformed beetle larvae in treatment ranges of between 10 minutes and 24 hours continuously or cumulatively over a period of 24 hours. ### Claim 21 (depends on 2) The process according to claim 2, wherein, during all or some of the light treatment, the transformed beetle larvae are kept in an environment having a substantially constant temperature of between 20 and 30° C., preferably between 26 and 28° C. ### Claim 22 (depends on 2) The process according to claim 2, wherein, during all or some of the light treatment, the transformed beetle larvae are kept in an environment having a substantially constant hygrometry of between 30 and 70% relative humidity, preferably between 30 and 40%. ### Claim 23 (depends on 1) The process according to claim 1, wherein the beetles are selected from the following species: Tenebrio Molitor, Alphitobius Diaperinus. ### Claim 24 (depends on 1) The process according to claim 1, further comprising, before the UV light treatment, a larvae pressing step in order to extract an oily fraction of said larvae. ### Claim 25 (canceled) ### Claim 26 (canceled) ### Claim 27 (canceled)
