รายงานวิจัยฉบับสมบูรณ์การศึกษาการใช้ประโยชน์จากโปรตีนไอโซเลตจากปลาข้างเหลือง (Selaroides leptolepis) ในไส้กรอกหมูลดไขมันและทดแทนไขมันด้วยน้ำมันถั่วเหลือ

In this work, the effects of partial replacement of porcine fat with soybean oil (SBO) on characteristics of sausages were firstly studied. The pre-emulsified SBO was prepared employing fish protein isolate, soy protein.งานวิจัยศึกษาผลของการทดแทนไขมันหมูบางส่วนด้วยน้ำมันถั่วเหลือง ที่มีผลต่อลักษณะของผลิตภัณฑ์ไส้กร้อก โดยการเติม SBO ในรูปที่ผ่านการเตรียมเป็นอิมัลชัน ด้วยการใช้โปรตีนไอโซเลตจากปลาข้างเหลือ

Controlled production of eco-friendly emulsions using direct and premix membrane emulsification

This paper was accepted for publication in the journal Chemical Engineering Research and Design and the definitive published version is available at http://dx.doi.org/10.1016/j.cherd.2015.04.009 .Eco-friendly O/W emulsions were produced by membrane emulsification using nickel membrane consisting of hexagonal arrays of cylindrical pores of 10 or 20 μm diameter and 200 μm spacing. The dispersed phase was a mixture of N,N-dimethyldecanamide (AMD-10TM) and d-limonene containing 0–35 wt% AMD-10TM in the dispersed phase and the continuous aqueous phase was 3 wt% polyoxyethylene glycerol fatty acid ester (Levenol® C-201). In direct membrane emulsification, the droplet-to-pore size ratio was 1.5–4.6 and the most uniform droplets were obtained with pure d-limonene at a stirrer speed of 620 rpm, corresponding to the peak shear stress on the membrane surface of 7 Pa. In premix membrane emulsification, the median droplet diameter decreased with increasing the transmembrane flux and was smaller than the pore size at the flux above 2000 L m−2 h−1. The droplet size was 6 μm after two passes through the membrane with a pore diameter of either 10 or 20 μm. The viscosity of emulsions with 30 wt% was not influenced by the shear rate but an emulsion with a dispersed phase content of 40 wt% showed shear thinning behaviour and viscoelastic properties. The produced emulsions can be used as environmentally friendly matrices for incorporation of agrochemical actives
