Problems solved by technology
Since phytosterol esters are oily substances, they are difficult to dissolve in water-soluble substances, and it is difficult to add them evenly in food. Moreover, when exposed to the air, their peroxide value is easy to increase, resulting in oxidative rancidity.
These factors have contributed to the limitations in the utilization of phytosterol esters

Embodiment 1
[0036] Partially skimmed milk: based on 100 parts by weight.
[0037] Concrete preparation method comprises the following steps:
[0038] (1) After passing the inspection, the fresh, antibiotic-free raw milk is partially degreased through a milk fat separator, so that the fat content in the final raw milk is 1.4%;
[0039] (2) Pasteurize for 30 minutes at 63°C;
[0040] (3) Cool the milk in step (2) to 32° C., add 0.011 parts by weight of commercial quark starter, and ferment for 120 minutes;
[0041] (4) During the fermentation process, when the pH value of the milk reaches 6.0, add 0.01 parts by weight of calcium chloride, adjust the calcium chloride to a 10% solution with distilled water before adding, add after heating and natural cooling;
[0042] (5) Add 0.01 parts by weight of rennet solution, and adjust the rennet into a 2% solution with 1% saline before adding. Incubate at about 30°C for 25 minutes and then add to the milk. After adding rennet, let it stand for 40...

The invention relates to the field of dairy product processing, in particular to low-fat quark cheese containing phytosterol ester microcapsules and a preparation method thereof. The phytosterol ester utilized in the invention is not only a novel cholesterol-lowering health food, but also has a certain effect on the texture of low-fat quark cheese. In the present invention, maltodextrin and gum arabic are used as embedding wall materials with a ratio of 1:1, and the phytosterol esters are microencapsulated by spray drying with an air inlet temperature of 190°C and an air outlet temperature of 85°C, and the phytosterol esters are encapsulated in milk Add before pasteurization and after clot-cut whey is drained. The present invention will obtain a quark cheese with cholesterol-lowering functional properties, and the texture and taste are easy to be accepted by consumers. At the same time, the present invention microencapsulates phytosterol esters to make it in a powder state, which will greatly broaden its The scope of use makes it effectively utilized in the food field. In addition, quark cheese has a high yield rate, short maturation period, fast production capital turnover, and good economic benefits for manufacturers, which are very conducive to production and promotion in my country.
Description
technical field [0001] The invention relates to a production method of quark cheese containing phytosterol ester microcapsules, and belongs to the technical field of dairy product processing. Background technique [0002] At present, epidemiological studies have confirmed that the higher the concentration of total cholesterol and low-density lipoprotein cholesterol in the blood, the higher the risk of suffering from coronary heart disease and coronary heart disease, and elevated blood lipids are also the main risk factors for cardiovascular and cerebrovascular diseases . Clinical prevention experiments have pointed out that the degree of increase in blood lipid concentration is directly related to the increase in the incidence of cardiovascular and cerebrovascular diseases. Therefore, reducing human cholesterol is an urgent problem to be solved at present, and people are paying more and more attention to personal dietary structure, and various long-term drug treatments will...
