Description

Technical Field

[0001] The invention belongs to the technical field of health food development, and particularly relates to a method for preparing fresh Dendrobium officinale pulp. Background Art

[0002] Dendrobium officinale is an orchidaceous herb and a traditional precious Chinese herbal medicine. It was first recorded in the "Shennong Herbal Classic" and is known as the first of the "Nine Immortal Herbs of China". It is highly safe and has antioxidant, anti-tumor, blood pressure lowering, blood sugar lowering, anti-inflammatory, skin care and hair growth promotion effects. It is widely used in health products, food and cosmetics. The main active ingredient of Dendrobium is polysaccharide, and the stem of Dendrobium is generally used as medicine. Chinese patent document CN103300450A discloses a method for preparing Dendrobium officinale pulp, which mainly involves baking the Dendrobium officinale until dry and then crushing it, adding water to pulp multiple times, filtering and combining the filtrate multiple times, and also requiring enzymolysis, and the preparation steps are complicated. The traditional processing method of Dendrobium officinale is to make fresh strips of Dendrobium officinale into pods, which have the effects of not being easy to mold, insect infestation and easy to preserve. After processing, the mucus components of Dendrobium are solidified and stabilized, and the effective ingredients are not easy to decompose. However, the traditional pod production process is complicated and the labor cost is high. If the method is not used properly, it is more likely to produce "dead grass" and lose raw materials. In previous studies, it was found that using hot air to dry Dendrobium officinale will cause the Dendrobium itself to respire and consume its own sugar during the drying process, and the polysaccharide retention rate is low. Summary of the invention

[0003] The object of the present invention is to provide a method for preparing fresh Dendrobium officinale pulp. By mixing and pulping fresh stems of Dendrobium officinale with a specific extract, and then filtering, Dendrobium officinale pulp with a high content of effective ingredients can be prepared. The preparation method provided by the present invention is simple, and the prepared Dendrobium officinale pulp can be used as a health food, which helps to resist oxidation and maintain a healthy blood sugar level.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0011] Preferably, the content of amino acids in the extract is 5-10 g / L, and the mass ratio of amino acids to citric acid is 1:0.7-1.

[0012] Preferably, the amino acid is lysine.

[0013] The use of alkaline lysine can further improve the extraction rate of active ingredients in Dendrobium officinale.

[0014] Preferably, the gelatinization temperature is 80-90° C. and the time is 40-60 min.

[0015] The second technical solution of the present invention is to provide a Dendrobium officinale puree prepared according to the above method for preparing Dendrobium officinale puree while it is fresh.

[0016] The third technical solution of the present invention is to provide a method for preparing a Dendrobium officinale puree product, comprising the following steps:

[0017] The Dendrobium officinale puree is sequentially subjected to degassing, homogenization, sterilization, canning, inner packaging sterilization and outer packaging to obtain a Dendrobium officinale puree product.

[0018] The fourth technical solution of the present invention: provides a Dendrobium officinale puree product prepared according to the above-mentioned preparation method of the Dendrobium officinale puree product.

[0019] The beneficial technical effects of the present invention are as follows:

[0020] The present invention uses an aqueous solution containing amino acids and citric acid as an extracting solution, and uses fresh stems of Dendrobium officinale to prepare Dendrobium officinale pulp, thereby increasing the yield of effective ingredients in Dendrobium officinale, and no preservatives or stabilizers are added during the process. The ingredients are natural and pure, and the pulp has good antioxidant properties, stable properties, and a sweet taste. Through further processing to form a Dendrobium officinale pulp product, consumers can directly drink the Dendrobium officinale pulp product, which can more fully absorb the nutritional essence of Dendrobium officinale compared to using dry Dendrobium or maple buckets to stew soup or make tea; compared to directly chewing fresh Dendrobium strips, directly drinking Dendrobium officinale pulp is a more convenient way to obtain it, there is no seasonality, and it also avoids the trouble of spitting out the residue after chewing.

[0025] The present invention provides a method for preparing a mature Dendrobium officinale puree product, the steps of which are as follows:

[0026] 1. Use annual stems of Dendrobium candidum as raw materials. Before crushing the raw materials, pick the stems of Dendrobium candidum, cut off the moldy sections, yellowed parts and residual pedicels, soak and wash them with clean water, and introduce ozone for more than half an hour to degrade harmful substances and preserve fresh stems;

[0027] The harvesting time of Dendrobium officinale stems is from early March to mid-April every year. Do not water the stems for at least three days before harvesting. After removing the leaves, dry them in the shade for 7 to 20 days and then put them into a fresh-keeping warehouse. The temperature setting range is 3℃ to 8℃. The Dendrobium officinale stems harvested under this condition can obtain the raw materials with the best viscosity and can be stored until early March of the following year.

[0028] 2. Crushing: Use multiple groups of sharp rotating blade crushers to crush the fresh Dendrobium strips, and repeat several times to make Dendrobium debris with a particle size of less than 5 mm.

[0029] 3. Grinding with water: Use a single-circulation stainless steel colloid mill, first add 5 to 10 times the mass of the Dendrobium debris with warm extract (40 to 60°C, the extract is an aqueous solution containing amino acids and citric acid), turn on the colloid mill, add the Dendrobium debris to the colloid mill several times and keep breaking it up, the duration is about 1 to 5 minutes, the temperature of the hopper pulp rises to 80°C to 90°C, maintains for 40 to 60 minutes, so that the Dendrobium candidum is completely gelatinized, and then discharged into the receiving tank for temporary storage.

[0030] 4. Centrifugal filtration: Use a rotor pump or a concentrated pulp pump to suck the raw pulp from the receiving tank into the flat centrifuge. The density of the filter bag should be above 100 mesh. The centrifugal time is generally 5 to 10 minutes. Depending on the filtering situation, decide whether to add material again or replace the filter bag. The filtrate is the raw pulp of Dendrobium officinale.

[0031] 5. Stirring and blending: Add or not add food additives to the filtered puree as needed, and stir continuously for more than 5 minutes.

[0032] 6. Degassing: The prepared raw pulp is passed through a degasser to remove air from the raw pulp.

[0033] 7. Homogenization: The degassed raw pulp is sucked into the homogenizer, and the raw pulp is homogenized at a pressure of more than 10Mpa according to its own machine parameters.

[0034] 8. Ultra-high temperature instantaneous sterilization: According to the needs (the timing starts from the crushing, and no operation is required if the raw pulp production and sterilization are completed within 8 hours), the homogenized raw pulp is sterilized at ultra-high temperature instantaneously at 135°C for 6 to 10 seconds, and then temporarily stored in a sterile tank for later use.

[0035] 9. Filling: Use filling equipment of different specifications to fill the raw pulp according to the needs.

[0036] 10. Use a sterilizer to sterilize the filled raw pulp at 121°C. Set the sterilization time for raw pulp packaging within 100 grams to 20 minutes to 25 minutes, for packaging within 100 grams to 150 grams to 26 minutes to 30 minutes, and for packaging above 150 grams to more than 30 minutes.

[0037] 11. Outer package the sterilized inner packaging as needed to obtain the Dendrobium officinale puree product.

[0038] In order to prove that the extract used in the production process of the present invention affects the yield of effective components in the Dendrobium officinale puree, the following experiment was conducted.

[0039] The L-aspartic acid, L-serine, L-lysine and citric acid used in the examples and comparative examples of the present invention are all commercially available raw materials.

[0040] The stems of Dendrobium officinale used in the embodiments of the present invention and the comparative examples are from the same batch of Dendrobium officinale harvested in early March. The stems are annual stems produced in Yunnan. After harvesting, they are sorted and the moldy sections, yellowed parts and residual pedicels are cut off.
