Description

[0001] The present application is a divisional application of the application filed on August 9, 2023, with the application number 202310999115.5, and the invention name of a seaweed dietary fiber rice and its preparation method. TECHNICAL FIELD

[0002] The present application relates to a kind of seaweed dietary fiber rice and its preparation method, belong to food processing technical field. BACKGROUND

[0003] Dietary fiber is a polysaccharide substance, which cannot be digested and absorbed by the gastrointestinal tract, nor can it produce energy. Therefore, it was once considered a "non-nutritive substance" and long-term did not get enough attention. However, with the in-depth development of nutrition and related life sciences, people gradually discovered that dietary fiber has quite important physiological functions, and it is recognized by modern medicine and nutrition as the "seventh nutrient" alongside the traditional six categories of nutrients: water, minerals, vitamins, proteins, fats and carbohydrates.

[0004] In the process of producing hydrocolloids such as carrageenan and agar from marine red algae such as Gracilaria and Eucheuma, the seaweed is subjected to impurity removal, pretreatment, water boiling, and filtration. The obtained clear liquid is refined carrageenan or agar gum, and the obtained solid is mainly seaweed dietary fiber, which is an excellent dietary fiber. In addition to its important role in human health, it also has good water retention, oil retention, thickening, and food taste improvement effects. Due to its marine origin, it contains a large amount of beneficial minerals and trace elements, making it have wide commercial value in the food and health industries.

[0005] Consuming an appropriate amount of dietary fiber is beneficial to human health, and obesity, high blood pressure, diabetes, etc. are all related to insufficient intake of dietary fiber. The FOA requires the minimum daily intake of dietary fiber to be 27g, the FDA recommends the intake of dietary fiber to be 20-35g per person (adult) per day, British nutritionists recommend the daily intake of dietary fiber to be 25-30g, and the Chinese Nutrition Society issued the daily reference intake of dietary nutrients in 2000, which is 20-35g.

[0006] With the improvement of living standards, people's diet is becoming more refined, and the proportion of animal meat food is increasing. The proportion of dietary fat production in some urban residents has increased from 20-25% a decade ago to 40-45% currently, and the intake of dietary fiber has decreased significantly. Each 100g of rice contains 0.7g of dietary fiber, and each 100g of steamed buns contains 1.0g of dietary fiber. Under the current dietary habits, it is not conducive to the supplementation of dietary fiber in the human intestinal tract.

[0007] Therefore, there is an urgent need in the art for a food that supplements daily dietary fiber. SUMMARY

[0008] The present application aims to provide a seaweed rice rich in seaweed dietary fiber to supplement the lack of dietary fiber in people's daily diet.

[0009] The present application solves the above technical problems by the following technical solutions: In the first aspect of the present application, a seaweed dietary fiber rice is provided, and the weight ratio of each component is as follows: seaweed dietary fiber 5-25%, rice flour 35-50%, potato powder 20-30%, cassava powder 20-30%, and gum ghatti 0-0.5%; wherein the seaweed dietary fiber is obtained by removing impurities, pretreatment, water boiling, and filtration of marine red algae or seaweed.

[0010] Preferably, the components further include konjac powder and sodium carbonate, the content of konjac powder is 0-5% and not 0%, and the content of sodium carbonate is 0-0.1% and not 0%.

[0011] Preferably, the marine red algae is Gracilaria or Eucheuma, and the seaweed is kelp.

[0012] In the second aspect of the present application, a preparation method of the above seaweed dietary fiber rice is provided, including the following steps: Step 1: uniformly mixing the seaweed dietary fiber, rice flour, potato powder, cassava powder, and gum ghatti in a proportion to obtain a mixture; Step 2: extruding the mixture obtained in step 1 into a strip; Step 3: granulating, polishing, drying, screening, sterilizing, and packaging the mixture obtained in step 2 to obtain the seaweed dietary fiber rice.

[0013] Preferably, the seaweed dietary fiber is Gracilaria, Eucheuma, or kelp.

[0014] In the third aspect of the present application, a preparation method of the above seaweed dietary fiber rice is provided, including the following steps: Step 1: uniformly mixing konjac powder and gum ghatti in a proportion to obtain a viscous solution; Step 2: uniformly mixing the seaweed dietary fiber, rice flour, potato powder, and cassava powder in a proportion, and adding the viscous solution obtained in step 1 to obtain a mixture; Step 3: adding sodium carbonate to the mixture obtained in step 2 and uniformly mixing; Step 4: extruding the mixture obtained in step 3 into a strip; Step 5: granulating, polishing, drying, screening, sterilizing, and packaging the mixture obtained in step 4 to obtain the seaweed dietary fiber rice.

[0015] Preferably, the seaweed dietary fiber is Gracilaria, Gracilaria dura or brown algae.

[0016] Compared with the prior art, the present application has the following beneficial effects: 1. The present application adds seaweed dietary fiber to ordinary rice, which supplements the lack of dietary fiber in today's eating habits.

[0017] 2. Seaweed dietary fiber itself contains active substances unique to marine plants, beneficial minerals and trace elements, which will provide people with health care effects.

[0018] 3. Seaweed rice is rich in seaweed dietary fiber, which can promote the multiplication of beneficial bacteria in the human intestinal tract, promote intestinal peristalsis, speed up detoxification, prevent constipation and reduce the risk of intestinal cancer, etc. BRIEF DESCRIPTION OF DRAWINGS
