Embodiment 1

[0029] Clean fresh lotus root, remove impurities, remove joints and skin, use a beater to beat, and pass through a 120-mesh vibrating sieve. The concentration of the slurry is controlled at 6%; the beating liquid is dehydrated at a speed of 1000 rpm, and the wet powder after dehydration The water content is controlled at 50%; put the dehydrated material into the storage tank, add water and stir, then pump it into the sedimentation tank, settle for 4 hours, and the water temperature is less than 18°C. After the end, drain the upper layer of water and control the remaining water within 1cm; add the dried finished powder to the sediment, the amount of which is 20% of the wet powder, fully mix the dry powder and the wet powder, and control the water content at 35% , the diameter of more than 95% of the wet powder block is controlled at less than 1cm; the wet powder is evenly sprinkled into the mixing screw, kept feeding at a constant speed, and enters the drying tower, and the dryi...

Embodiment 2

[0031]Clean fresh lotus root, remove impurities, remove joints and skin, use a beater to beat, and pass through a 120-mesh vibrating sieve. The concentration of the slurry is controlled at 8%; the beating liquid is dehydrated at a speed of 1500 rpm, and the wet powder after dehydration The water content is controlled at 55%; put the dehydrated material into the storage tank, add water and stir, then pump it into the sedimentation tank, settle for 8 hours, and the water temperature is less than 18°C. After the end, drain the upper layer of water and control the remaining water within 1cm; add the dried finished powder to the sediment, the amount of which is 25% of the wet powder, fully mix the dry powder and the wet powder, and control the water content at 50% , the diameter of more than 95% of the wet powder block is controlled at less than 1cm; the wet powder is evenly sprinkled into the mixing screw, kept feeding at a constant speed, and enters the drying tower, and the dryin...

Embodiment 3

[0033] Clean fresh lotus root, remove impurities, remove joints and skin, use a beater to beat, and pass through a 120-mesh vibrating sieve. The concentration of the slurry is controlled at 7%; the beating liquid is dehydrated at a speed of 1200 rpm, and the wet powder after dehydration The water content is controlled at 53%; put the dehydrated material into the storage tank, add water and stir, then pump it into the sedimentation tank, settle for 6 hours, and the water temperature is less than 18°C. After the end, drain the upper layer of water and control the remaining water within 1cm; add the dried finished powder to the sediment, the amount of which is 23% of the wet powder, fully mix the dry powder and the wet powder, and control the water content at 45% , the diameter of more than 95% of the wet powder block is controlled at less than 1cm; the wet powder is evenly sprinkled into the mixing screw, kept feeding at a constant speed, and enters the drying tower, and the dryi...

Abstract

The present invention discloses homologous soluble dietary fiber intensified lotus root starch and a preparation method thereof, and relates to the technical field of processing of food / agricultural products and by-products or wastes thereof. The homologous soluble dietary fiber intensified lotus root starch is characterized in that soluble dietary fibers are derived from the waste of lotus root residues during production and processing processes of lotus root juice. The preparation method of the lotus root starch comprises lotus root pre-treating, slurry grinding, dehydrating, precipitating,primary drying, soluble dietary fiber material blending, stirring, granulating, secondary drying, packaging, etc. The qualified lotus root starch is melt once enters mouth, has a water content of 5-7.5% and has a soluble dietary fiber content of 3%-5%. The production process is clean, environmentally friendly, simple in technology and easy for industrialized production.

Description

technical field [0001] The invention belongs to the technical field of processing food / agricultural products and by-products thereof, relates to lotus root powder and its preparation technology, and specifically provides a lotus root powder fortified with homologous soluble dietary fiber and a preparation method thereof. Background technique [0002] Lotus (Nelumbo Nucifera) is a large perennial aquatic herbaceous plant of the family Nymphaeaceae. It is native to China and India. In my country, it is mainly distributed in the shallow water areas of the Yangtze River, Yellow River, Pearl River and freshwater lakes. Both lotus root and lotus seeds are rich in nutrients, and are well-known delicacies with high health value. Therefore, in recent years, the planting area of ​​lotus root in my country has reached more than 7 million mu, and the annual output of lotus root is nearly 100 million tons. Lotus root is the plump underground stem of lotus root, slightly sweet and brittle...
