Benefits of technology

This patented technology allows us to produce both edible fibers like citrus pulp (orange) and insufficient nutrients called xanthoceras or vitamins found naturally within them. By extracting these valuable components along with other materials that help improve their taste quality, this new type of food could be more affordable than traditional sources due to its natural content.

Problems solved by technology

Technological Problem: Current Diets containing fibers like orange pea (fava) may cause harmful side effects due to their lack of bioavailability. Existing sources include extractable ingredients with poor absorption capabilities, making them difficult to absorb into bloodstream through gastrointestinal tract tissues without causing damage. There exists technical problem addressed in this patents where there is no effective way to make dietetical fiber available at reasonable cost while maintain its beneficial properties.

Embodiment 1

[0042] Add alkaline solution to orange dregs. The alkali solution is 10% sodium hydroxide, and the amount added is 15 times that of orange dregs. The orange pomace after adding alkali is treated with ultrasonic for 10min to cause sonic cavitation between the alkali solution and the orange pomace, increase the contact area between the orange pomace and the alkali solution, and increase the transfer rate of soluble substances into the alkali solution. After ultrasonic treatment, the material is soaked for 1 hour and then transferred to the next step.

[0043] The soaked orange pomace is then processed by a single screw extruder.

[0044] Then it is filtered to separate the filter residue A and the filtrate A. The filter residue A is washed with a small amount of water to recover the soluble substances carried into the filter residue, and the washing water is incorporated into the filtrate A.

[0045] Perform alcohol precipitation. Add 4 times of absolute ethanol to the filtrate A, ...

Embodiment 2

[0053] The orange pomace is added to the alkali solution. 15% sodium hydroxide is selected as the lye, and the amount added is 16 times that of orange dregs. The orange pomace after alkali addition was treated with ultrasound for 20 minutes. After ultrasonic treatment, the material is soaked for 2 hours and then transferred to the next step.

[0054] The soaked orange pomace is then processed by a single screw extruder.

[0055] Then it is filtered to separate the filter residue A and the filtrate A. The filter residue A is washed with a small amount of water, and the washing water is incorporated into the filtrate A.

[0056] Perform alcohol precipitation. Add 4 times of absolute ethanol to the filtrate A, stir evenly, and filter after standing for a period of time. Filter to obtain filtrate B and filter residue B.

[0057] The filtrate B is distilled to obtain a distillate and an aqueous phase. The distillate ethanol is reused for alcohol precipitation. The water phase is reu...

Embodiment 3

[0064] Add alkaline solution to orange dregs. The alkali solution is 12% sodium hydroxide, and the amount added is 15 times that of orange dregs. The orange pomace after adding alkali is treated with ultrasonic for 15min to cause sonic cavitation between the alkali solution and the orange pomace, increase the contact area between the orange pomace and the alkali solution, and increase the transfer rate of soluble substances into the alkali solution. After ultrasonic treatment, the material is soaked for 1.5 hours and then transferred to the next step.

[0065] The soaked orange pomace is then processed by a single screw extruder.

[0066] Then it is filtered to separate the filter residue A and the filtrate A. The filter residue A is washed with a small amount of water to recover the soluble substances carried into the filter residue, and the washing water is incorporated into the filtrate A.

[0067] Perform alcohol precipitation. Add 4 times of absolute ethanol to the filtrate ...

Abstract

The invention discloses a method for producing dietary fiber with by-product orange dreg of orange juice, and is characterized in that the by-product orange dreg after squeezing and producing orange juice is used as raw material; the orange dreg is soaked in alkali, impacted by ultrasonic and processed by an extruder; after post treatment process, soluble dietary fiber and insoluble dietary fiber are simultaneously obtained. The invention uses by-product of orange juice as raw material, thereby avoiding resource waste and environmental pollution; and the producing method increases the producing rate, reduces the cost and increases the profit.
