This invention proposes a bioecological process for utilizing waste from sugary drinks by producing highly nutritious proteins from single-celled organisms, as well as other molecules of various interest, while significantly reducing the pollutant load of this waste. The process involves the upstream separation of the returned products, which are highly concentrated in sugars. The first step involves preparing the musts for fermentation by degassing and adjusting the sugars to 20 g / L and the pH to 5. An enrichment matrix is ​​used for musts made from carbonated beverage waste. The culture is carried out in batch or semi-continuous mode at a temperature of 30 ± 2°C with an agitation speed of approximately 150 rpm and oxygenation to promote oxidative metabolism. The incorporation of nectars and juices into the fermentation musts of carbonated beverages at a rate of ≥ 50% ensures a significant improvement in biomass yields. The process guarantees almost complete depletion of the sugars initially present in the musts (≥ 95%), producing biomass with a protein content exceeding 50% on a dry matter basis, which can be used in animal feed, aquaculture, or cosmetics.

This invention discloses a cold-induced gelled nutrient protein jelly made from Antarctic krill and its preparation method, belonging to the field of nutritional food processing technology. The method includes: preparing a high internal phase emulsion containing Antarctic krill oil; obtaining Antarctic krill protein from cooked Antarctic krill meat through alkali extraction and centrifugation; mixing the high internal phase emulsion and Antarctic krill protein at a mass ratio of 20:80 to 30:70, adding 0.2 to 0.4 wt% κ-carrageenan, adjusting the pH to 7 to 8, and cold-inducing gel formation at 0 to 10°C; then subjecting the mixture to ultra-high pressure treatment at 300 to 500 MPa for 10 to 30 minutes to obtain the nutrient protein jelly. The resulting product possesses the nutritional composition of Antarctic krill protein, whey protein, and Antarctic krill oil, with adjustable texture, and is suitable for the preparation of nutritional gel foods.
