Abstract
Description
Technical Field
[0001] The invention relates to the technical field of food, in particular to a zero-additive fresh-squeezed corn juice beverage and a preparation method thereof. Background Art
[0002] Among all staple foods, including those made from white flour and rice, corn has the highest nutritional value and health benefits. In particular, its vitamin content is 5-10 times that of rice and wheat. Corn also contains 7 "anti-aging agents": calcium, glutathione, vitamin A, magnesium, selenium, vitamin E and fatty acids.
[0003] However, in the traditional corn juice beverage production process, in order to improve the taste of the beverage, extend the shelf life or improve production efficiency, some food additives are usually added, such as stabilizers (sodium carboxymethyl cellulose, xanthan gum, pectin, etc.), sweeteners, preservatives, etc. Although these additives can meet the production needs to a certain extent, they also bring several problems:
[0004] (1) Consumers have doubts about the safety of food additives and worry that long-term intake will have adverse effects on their health.
[0005] (2) In the absence of additives, the shelf life of some beverages at room temperature is short, which greatly reduces the consumer's purchasing experience and the storage capacity of shopping malls. Summary of the invention

[0007] In order to solve the above problems, the technical solution of the present invention is a zero-additive freshly squeezed corn juice beverage, which is composed of the following materials in parts by weight:
[0008] Fresh corn kernels: 30-40 servings;
[0009] White sugar: 5-7 parts;
[0010] 55-65 parts of drinking water.
[0011] Furthermore, the fresh corn kernels are of the sweet corn category.
[0012] A method for preparing a zero-additive freshly squeezed corn juice beverage comprises the following steps:
[0013] S1, passing the quick-frozen sweet corn through a screw conveyor at a uniform speed into a colloid mill for three consecutive beatings, wherein hot water at a certain temperature is added to the sweet corn kernels in a proper proportion during the first beating, and the mixture is ground until there are no particles and then collected;
[0014] S2, heating the corn syrup to a certain temperature and keeping the temperature constant for a certain period of time, and then putting it into a blending tank;
[0015] S3, adding sugar water and corn syrup into the mixing tank, mixing evenly, setting the volume to a predetermined liquid level, and stirring for a period of time;
[0016] S4, after the liquid is preheated and degassed, it is homogenized in a homogenizer, and after a certain pressure is set, it is sterilized by a UHT system, a certain sterilization temperature is set, and the sterilization time is 15 seconds. The flow rate of the liquid after sterilization is controlled within a certain range, and the outlet temperature is controlled within a certain range;
[0017] S5. The liquid after UHT sterilization enters the aseptic tank, and then is aseptically cold filled, and the filling requirements are strictly controlled.
[0018] Furthermore, in step S2, the heating temperature of the corn steep liquor is 85° C. to 90° C., and the constant temperature time is 25 to 40 minutes.
[0019] Furthermore, in step S4, the pressure setting range is 22-25 MPa, the sterilization temperature setting range is 139±1°C, the liquid flow rate is controlled to 12 tons / hour, and the outlet temperature is controlled to 13-25°C.
[0020] Furthermore, after UHT sterilization and aseptic cold filling, the sweet corn juice can be stored at room temperature for up to 9 months without affecting the quality.
[0021] Furthermore, the temperature of the hot water during the first refining in step S1 is greater than or equal to 80° C., and the ratio of the hot water to the sweet corn kernels is 0.5-0.8:1.
[0022] Furthermore, the stirring time in step S3 is 10-15 minutes.
[0023] Furthermore, the filling requirements are torque and air tightness, the torque is controlled between 1.8-2.9Nm, and the air tightness test condition is 0.4Mpa pressure for 1 minute.
[0024] The advantages of the present invention compared with the prior art are:
[0025] 1. The present invention provides a zero-additive freshly squeezed corn juice beverage and a preparation method thereof, wherein the sweet corn kernels are finely ground three times in a colloid mill, and then pre-gelatinized, and then subjected to high shearing action of a high-pressure homogenizer, so that the sweet corn juice has a delicate taste and a uniform texture, and no stabilizer needs to be added;
[0026] 2. The present invention provides a zero-additive fresh-squeezed corn juice beverage and a preparation method thereof. The sweet corn juice is subjected to UHT (ultra-high temperature instantaneous sterilization) and aseptic cold filling, which can maximize the retention of its nutrients and can have a shelf life of up to 9 months at room temperature.

[0056] For specific use, refer to Figures 1 to 5 As shown,
[0057] 1. Raw material preparation
[0058] 1. Choose freshly picked sweet corn kernels, 35 parts by weight (can be adjusted between 30 and 40 parts according to actual production), to ensure that the corn kernels are full, free of pests and diseases, and have high sweetness.
[0059] 2. Choose high-quality white sugar, 6 parts by weight (can be adjusted between 5 and 7 parts according to taste requirements) to adjust the sweetness of the corn juice.
[0060] 3. Use purified water that meets drinking water standards, 60 parts by weight (can be adjusted between 55 and 65 parts according to actual conditions) to ensure the purity and safety of the product.
[0061] 2. Production process
[0062] S1. Feed the quick-frozen sweet corn kernels into the colloid mill at a uniform speed through a screw conveyor, and perform three consecutive beating operations. When grinding for the first time, add hot water with a temperature not lower than 80°C, and control the ratio of hot water to sweet corn kernels at 0.6:1 (the range can be adjusted to 0.5-0.8:1) to ensure that the corn kernels are fully softened and ground to a particle-free state. Collect the corn pulp after the first grinding for later use.
[0063] S2. The corn syrup obtained in step S1 is heated to 88° C. (ranging from 85° C. to 90° C.), and maintained at this temperature for 30 minutes (ranging from 25 to 40 minutes) to promote the release and homogenization of the nutrients in the corn.
[0064] S3, in a mixing tank, the corn syrup treated in step S2 is mixed with pre-dissolved sugar water (white sugar and water are mixed in proportion), and evenly mixed by a stirrer until a predetermined liquid level is reached. The stirring time is set to 12 minutes (the range can be adjusted to 10-15 minutes) to ensure that the sugar water and corn syrup are fully integrated.
[0065] S4. After preheating the prepared liquid to the appropriate temperature, send it to the homogenizer for homogenization. Set the pressure to 24Mpa (adjustable to 22-25Mpa) to improve the taste of the product. Then, the liquid is sterilized by the UHT (ultra-high temperature instantaneous sterilization) system. Set the sterilization temperature to 139℃±1℃ and the sterilization time to 15 seconds to ensure the microbial safety of the product. After sterilization, control the liquid flow rate to 12 tons / hour and the outlet temperature to 20℃ (adjustable to 13-25℃) to avoid overheating of the product and affect its quality.
[0066] S5. The UHT sterilized liquid enters the aseptic tank directly, followed by aseptic cold filling. During the filling process, the torque is strictly controlled at 2.3Nm (the range can be adjusted between 1.8-2.9Nm), and the air tightness test is carried out. The test condition is 0.4Mpa pressure for 1 minute to ensure good product sealing.
