Embodiment 1
[0018] Dissolve 2g of monoglyceride, 4g of lecithin and 1g of Tuwin-60 in 875g of demineralized water at a temperature of 50-70°C, and add 84g of octenyl succinic esterified starch HI-CAP100 and 126g in sequence while stirring Maltodextrin, dissolves evenly to form a wall material aqueous solution;
[0019] Add 140g of walnut oil to the above-mentioned wall material aqueous solution, and keep the temperature of the feed liquid at 50-70°C, pass through a colloid mill, and homogenize under high pressure for 2-3 times under a pressure of 35-40MPa;
[0020] Then, a centrifugal spray dryer is used to carry out spray drying at an air inlet temperature of 180-190°C and an outlet air temperature of 80-90°C to obtain a powdered walnut oil product. The microencapsulation efficiency of the walnut oil powder is 99.82%.
Embodiment 2
[0022] Prepare powdered walnut oil in the same manner as in Example 1, the difference being that used monoglyceride, lecithin, 1g soil temperature-60, demineralized water, octenyl succinic esterified starch HI-CAP100, maltodextrin and The weight of walnut oil is respectively 1g, 2g, 0.5g, 500g, 50g, 75g and 75g. The microencapsulation efficiency of the obtained powdered walnut oil was 95.52%.
Embodiment 3
[0024] Prepare powdered walnut oil in the same manner as in Example 1, the difference being that used monoglyceride, lecithin, 1g soil temperature-60, demineralized water, octenyl succinic esterified starch HI-CAP100, maltodextrin and The weight of walnut oil is respectively 3g, 6g, 9g, 1100g, 73g, 183g, 183g. The microencapsulation efficiency of the obtained powdered walnut oil was 90.28%.

Abstract
The present invention discloses a method for preparing powder walnut oil with high embedding rate. Said method includes the following steps: (1), after the monoglyceride, lecithine and Tween-60 as emulsifying agent are dissolved in water, successively adding octylene succinic acid esterified starch HI-CAP100 and maltodextrin as wall material to obtain wall material aqueous solution for stand-by; (2), adding walnut oil into the above-mentioned wall material aqueous solution, shearing and homogenizing to make the walnut oil be uniformly dispersed in the wall material aqueous solution; under the action of emulsifying agent forming O/W (oil-in-water) type emulsion with good emulsification stability; and (3), utilizing drying process to remove water content from emulsion, making wall material be formed into film, then the walnut oil can be uniformly embedded by all material film so as to obtain the invented powder walnut oil with high embedding rate.
Description
technical field [0001] The invention relates to the field of food processing, in particular to a method for preparing embedded powdered walnut oil. Background technique [0002] Liquid oils, such as walnut oil, soybean oil, etc., are easy to oxidize and deteriorate when exposed to the air, so the storage time is short, generally about 6 months. In addition, liquid oil is insoluble in water, and it is often used to prepare milk powder, so it is inconvenient to use. Therefore, it is usually necessary to embed liquid oil to make powdered liquid microcapsule oil, which not only isolates the air, but also protects the unsaturated fatty acids in the oil, effectively prolongs the storage time, and improves the stability of the oil during use. convenience. [0003] Walnut oil is a very high-grade and precious nutritional oil. Its saturated fatty acids mainly include palmitic acid and stearic acid (the total amount is less than 10%), and the unsaturated fatty acids mainly include o...
