The present invention relates to a method for producing biofuel from a stream comprising an unsaturated oil derived from a biosourced raw material and / or waste, characterised in that a mercaptan of the following general formula (I) is added upstream or at the inlet of the preheating device: X-R1-Y (I) wherein: - R1 is a linear or branched (C1-C30) alkylene; - X is selected from a hydrogen atom, HO-, HOOC- or HS-(CH2)n-C(O)-O-, n being an integer between 1 and 8; - Y is an -SH group or a hydrogen atom; and wherein, if Y is a hydrogen atom, X is an -O-C(O)-(CH2)n-SH group. The mercaptan may also be combined with another sulphur compound, in particular dimethyl disulphide.

This invention specifically relates to a nano-adjusting agent for enhancing oil recovery and its preparation method. The adjusting agent of this invention consists of 0.1%–2.0% amphiphilic polymer, 0.1%–0.8% surfactant system, 0.5%–1.0% nanofiller, and 0.5%–3.0% retarder. The hydrophilic polymers are polyacrylamide, polyacrylic acid, and their copolymers, and the lipophilic polymer polystyrene; the surfactant system is a compound system consisting of a nonionic surfactant (fatty alcohol polyoxyethylene ether, EO number 12) and an anionic surfactant (sodium dodecylbenzenesulfonate); the nanofiller is amino-modified silica nanoparticles; and the retarder is polyether polyol and sorbitol. The results of the examples show that the adjusting agent has a high adsorption capacity on hydrophilic surfaces and a low adsorption capacity on lipophilic surfaces; it also has a high adsorption capacity on unsaturated oil core surfaces and a low adsorption capacity on saturated oil core surfaces, all indicating excellent selective adsorption properties.

This invention belongs to the field of feed technology and provides a fermented feed for increasing the Omega-3 content of broilers and its preparation method. The invention uses soybean protein isolate and maltodextrin to prepare a covalently conjugated wall material to encapsulate the Omega-3 oil phase into microcapsules via Maillard reaction. A dual-protection design, involving low-temperature mixing of this microcapsule with a fermentation matrix, achieves controllable particle size (median particle size 12-27 μm), long-term oxidative stability with a surface oil content of 0.8-1.8 wt% and a peroxide value of 0.5-3.5 meq / kg, as well as resistance to abrasion under mixed storage and transportation machinery and effective release performance during digestion. This invention solves the technical contradictions of existing unsaturated oil microcapsule systems in high-solids processing, high oil-carrying stability, and application coupling performance, and has significant application value in increasing the Omega-3 content of broiler muscle and improving the nutritional quality of poultry meat.
