AI Technical Summary

Technical Problem

Existing technologies lack systematic breeding and harvesting processes for obtaining black soldier fly oil with high palmitic acid content, resulting in a reliance on palm oil as the primary source of palmitic acid, with a lack of sustainable alternative raw materials.

Method used

By controlling the hatching, rearing conditions, and harvesting time of black soldier flies, and combining Soxhlet extraction to extract lipids from black soldier fly larvae, high palmitic acid black soldier fly oil was prepared. Agricultural processing by-products such as wheat bran and cassava residue were used as feed, and the lipids were extracted after being crushed.

Benefits of technology

The preparation of black soldier fly oil with high palmitic acid content of 45%~47% has been achieved, providing an environmentally friendly and sustainable alternative raw material suitable for cosmetics and industrial oils, reducing raw material costs and realizing the resource utilization of agricultural waste.

Abstract

This invention relates to the field of insect resource utilization and agricultural waste treatment technology, specifically to a high-palmitic acid black soldier fly oil, its preparation method, and its applications. The preparation method of high-palmitic acid black soldier fly oil includes the following steps: black soldier fly eggs are hatched and reared in a hatching substrate to obtain larvae; the larvae are inoculated into a culture feed and then harvested to obtain black soldier fly larvae; the black soldier fly larvae are cleaned, have internal residues removed, dried, and pulverized, and then subjected to lipid extraction to obtain high-palmitic acid black soldier fly oil. The harvesting time is 5-7 days. This invention obtains black soldier fly oil with a palmitic acid content of up to 45%-47% by rearing black soldier flies, providing a sustainable alternative raw material for palmitic acid derived from insect biotransformation, with significant environmental advantages. The key parameters of this invention are clearly defined, the operation is simple, and the proportion of palmitic acid in the obtained product is stable, making it suitable for industrial-scale production.
