Problems solved by technology

The few deep-processed products still use the traditional and relatively backward technology, such as water extraction and alcohol precipitation or alcohol extraction and water precipitation. Even if ultrasonic and microwave enhanced extraction is used, it needs to be concentrated under reduced pressure, dried, and sterilized under subsequent heating conditions. The extraction rate is low, the loss of active ingredients and heat-sensitive substances is large, the waste of resources is large, and it is difficult to realize its health care and pharmacological effects

Embodiment 1

[0071] 1. Clean fresh sweet potato tender stems, leaves and tubers (removing weeds, yellow leaves and old stems, etc.) with drinking water, put them in stainless steel mesh baskets, drain free water, and then use a vegetable cutter Cut into about 0.5-1cm 3 small pieces or blocks.

[0072] 2. Put the small pieces or small pieces obtained in step 1 into a beater for beating, and then send them into a colloid mill for further grinding, and centrifuge to remove slag in a high-speed centrifuge at a speed of 3000rpm for 20 minutes. The slag and step 1 The removed old vine leaves are processed into livestock feed, and the clear liquid enters the subsequent process.

[0073] 3. Add β-cyclodextrin in the clear liquid obtained in step 2, and its consumption is 0.4‰ of the weight of sweet potato vine leaves and tubers described in step 1, and input in the container of ultra-high pressure equipment, carry out ultra-high pressure extraction and kill Bacteria, the specific operating condi...

Embodiment 2

[0081] 1. Clean fresh sweet potato tender stems, leaves and roots (removing weeds, yellow leaves and old stems, etc.) with drinking water, put them in stainless steel mesh baskets, drain free water, and then use a vegetable cutter Cut into about 0.5-1cm 3 small pieces or blocks.

[0082] 2. Put the step 1 into the beater for beating, then send it to the colloid mill, further grind it, and remove the slag by centrifuging at a speed of 3500rpm for 25 minutes. The slag and the old stems and leaves removed in step 1 are used to process livestock feed , the supernatant enters the follow-up process.

[0083] 3. Add β-cyclodextrin to the clear liquid of step 2, and its consumption is 0.5‰ of the weight of sweet potato vine leaves and tubers described in step 1, and input it into the container of ultra-high pressure equipment for ultra-high pressure extraction and sterilization , the specific operating conditions are: at 45°C, 300Mpa, for 25 minutes.

[0084] 4. The supernatant aft...

Abstract

The invention relates to a method for preparing functional nourishment by using deep-processed sweet potatoes. The method comprises the following steps of (1) smashing canes, leaves and tuberous roots of sweet potatoes to pulp and separating the pulp to obtain clear liquid and dregs; (2) adding molecular complexing agents to the clear liquid which is obtained from the step (1) and performing ultrahigh pressure cell-breaking extraction and sterilization on the clear liquid; (3) performing membrane separation and low-temperature drying on the clear liquid which is obtained by extraction and sterilization from the step (2) so that the water content of the material reaches 5 to 10 in percentage by weight; and (4) smashing the material which is obtained by drying from the step (3) to obtain dry powder of sweet potato extracts which can pass through a sieve with meshes of 40 to 80 and preparing the dry power to formulation which is acceptable in nourishment processing according to the conventional method. By the method for preparing the functional nourishment by using the deep-processed sweet potatoes, the whole process can be completed at low temperatures, the specific processes of molecular complexing, ultrahigh pressure cell-breaking extraction and sterilization, membrane separation concentration and low-temperature drying are fully utilized, a new deep-processing technology of the sweet potatoes is formed, and the technology is remarkably improved as a whole.

Description

technical field [0001] The invention relates to the field of agricultural product processing, in particular to a technology for obtaining functional nutritional products through deep processing of sweet potatoes. Background technique [0002] Sweet potato (Ipomoea batatas L.) is an annual or perennial plant of the Convolvuaceae family, native to Latin America, also known as sweet potato, sweet potato, sweet potato, sweet potato, red yam, sweet potato scorpion, fanru, soil melon, golden potato, Zhushu and so on. It is cultivated in a wide area, with high yield and strong adaptability. It is an important food crop in my country, and it also has high medicinal value. Its pharmacological effects have been clearly recorded in the "Compendium of Materia Medica" in the Ming Dynasty to the "Dictionary of Chinese Medicine": " Tonify deficiency and exhaustion, strengthen energy, strengthen spleen and stomach, strengthen kidney yin", "nature is mild and non-toxic, strengthen spleen and...
