Description
Technical Field
The invention relates to liquid milk, in particular to liquid milk for pregnant women, which is directly sterilized by steam injection, and a preparation method thereof. Belongs to the technical field of dairy products.
Background
The healthy nutritional diet not only plays a role in promoting the growth and development of fetuses, but also is beneficial to the health of pregnant women. The gestation period is not the simple addition of the normal physiological metabolism of the pregnant woman and the development process of the fetus, but the comprehensive adjustment process of the physiological function of the pregnant woman. Pregnant women, in addition to maintaining their own basal metabolism and needs for life and labor, also have special nutritional needs because they are burdened with the need for fetal growth and development, placental nutrition and maternal tissue proliferation. Good diets not only reduce the risk of complications such as infection, anemia and pregnancy poisoning in the mother, but also reduce the likelihood of premature delivery, underweight, stillbirth, brain damage and stunted development in the infant. Furthermore, accumulation of nutrients from the beginning of pregnancy is also very necessary in preparation for consumption of physical strength and nutrients during childbirth, such as exertion, bleeding, postpartum lactation, and childbirth. At present, the types of milk substitutes for pregnant women in the market of China are limited, most of milk powders need to be mixed with water, and the nutritional ingredients are not comprehensive, so that the production of reasonable milk substitutes suitable for the pregnant women is urgent. In particular to pregnant woman liquid milk which is convenient to drink.
Disclosure of Invention
The invention aims to provide the liquid milk which has comprehensive nutrient components and is convenient to drink and suitable for pregnant women.
990Kg of milk (or reconstituted milk), 1.5 to 5Kg of emulsion stabilizer, 0.8 to 600 g of vitamin complex, 120 to 340g of complex mineral, 5 to 15Kg of prebiotics and 0.15 to 1Kg of algae DHA oil. The liquid milk has more reasonable nutrient components so as to meet the requirements of pregnant women in special physiological periods. Compared with fresh milk and common milk powder, the product has the advantages of scientific nutrition proportion, fragrant and strong flavor and convenient eating.
The milk can be selected from fresh milk, or whole milk powder or other milk products (skimmed milk powder, whey protein concentrate, buttermilk powder, etc.) can be combined to form reconstituted milk, which can provide the nutrients of the fresh milk in the invention.

Trial experiment for pregnant woman
100 pregnant woman volunteers are selected to drink pregnant woman milk powder and pregnant woman milk during the period of 2006-2008 for 2 months. The pregnant woman volunteers are healthy, the blood pressure is normal, no anemia exists, no serious family genetic disease history exists, and no bad life habits such as alcoholism, smoking and the like exist. The annual income of the family is 5-8 ten thousand yuan. The pregnant woman drinks 500ml of pregnant woman milk every day, and the amount of the pregnant woman milk powder is converted into the volume of the liquid product.
The development conditions of the fetus at the early, middle and late stages of pregnancy in the mother are determined, and the influence of the pregnant woman milk powder and the pregnant woman milk on the growth and development of the fetus is evaluated.
In the early stage of pregnancy, the small fetal sac can be seen through B-ultrasonic at 5 weeks, and the shape of the fetal sac is clear and is circular or elliptical. After 10 weeks of pregnancy, the fetal sac begins to disappear through B-ultrasound, the crescent-shaped placenta is visible, and the fetus is active in amniotic fluid. The pregnant women and fetuses drinking the pregnant woman milk powder and the pregnant woman milk have normal conditions.
The double apical diameters of the fetal head are the distance between the apical bones at the two sides of the fetal head, and are indexes for measuring the development and size of the fetus; is also the main index of whether the fetus can pass through the birth canal. In addition, the fetal abdominal circumference and the length of the femur (femur length) are selected as main observation indexes to carry out dynamic continuous observation and evaluate the growth and development conditions of the fetus.
The fetal head double apical diameter, abdominal circumference and femoral length in the middle and later stages of pregnancy are measured under the condition of drinking different dairy products, and the results are shown in table 1.
TABLE 1 fetal head, double apical diameter, abdominal circumference, and femoral length in the middle and late stages of pregnancy
Unit: cm
As can be seen from the results in Table 1, there was no significant difference in the growth and development of the fetus when the pregnant women took the milk powder and the milk. The data in table 1 are all within the reference index for normal fetal growth. It is proved that the health of the pregnant woman and the fetus is ensured by drinking the pregnant woman milk.
Pregnant woman who drinks the milk powder and milk concentrates mind in a quiet room, and lies on the side, the pregnant woman can make several fetal movements for 3 times in the morning, in the middle and at night. Each time 1 hour and the number of fetal movements is recorded in the table, and the sum of the number of 3 fetal movements is multiplied by the total number of fetal movements of 4 hours to 12 hours. Tests show that the number of fetal movements is more than 30 on average. And falls within the normal range.
After 28 weeks of gestation, listen 2-3 times a day, each for 1-2 minutes. The health condition of the expectant mothers drinking the milk powder and the milk of the pregnant women is normal. Under the non-sleep condition of the fetus, the normal frequency of the fetal heart is in the range of 120-160 times/minute.
Compared with the pregnant woman milk powder, the pregnant woman milk overcomes the difference of water adding proportion when the formula powder is artificially fed, and ensures the reasonable content of the nutrient components; the disadvantages of non-uniformity and coarse particles in brewing are also avoided. The research shows that the pregnant woman milk has balanced nutrition, mellow taste and easy absorption, can meet the nutritional requirements of pregnant women and the normal growth and development of fetuses. And is convenient for drinking.
