Embodiment 1

[0016] Take Jiangyongxiang pomelo green fruit 150Kg, use 0.5% (mass ratio) Na 2 CO 3 Wash the green fruit with the solution, grind the green fruit with an oil mill, wash with demineralized water, and filter the oil-water mixture after the oil grinding through a sieve. The filtrate is centrifuged at high speed, and the oil layer and water layer are separated by an oil-water separator. Use a siphon to suck out the upper oil layer and store it at a low temperature below 5°C. The refined essential oil yield is about 0.5%. The residual fruit after the oil grinding is crushed to 2-3mm, put into the reaction tank, add 600kg of demineralized water, adjust the pH value to 1-2 with 20-25% industrial hydrochloric acid (mass concentration), and then add 0.1% by weight of Sodium hexametaphosphate, heated by steam, stirred and heated at 85°C for 0.5 hours, centrifuged, and the pectin solution obtained after coarse filtration through a 200-mesh filter cloth was used for separation and con...

Embodiment 2

[0019] Take Jiangyongxiang pomelo secondary fruit 150Kg, use 0.5% (mass ratio) Na 2 CO 3 Wash the green fruit with the solution, grind the green fruit with an oil mill, wash with demineralized water, and filter the oil-water mixture after the oil grinding through a sieve. The filtrate is centrifuged at high speed, and the oil layer and water layer are separated by an oil-water separator. Use a siphon to suck out the upper oil layer and store it at a low temperature below 5°C. The refined essential oil yield is about 0.8%. The residual fruit after the oil grinding is crushed to 2-3mm, put into the reaction tank, add 600kg of demineralized water, adjust the pH value to 1-2 with 20-25% industrial hydrochloric acid (mass concentration), and then add 0.1% by weight of Sodium hexametaphosphate, heated by steam, stirred and heated at 85°C for 1.5 hours, centrifuged, and the pectin solution obtained after coarse filtration through a 200-mesh filter cloth is used for separation and ...

Abstract

The present invention relates to a processing process for comprehensive utilization of pomelo green fruit, rejected fruit and fruit peel. Said processing process includes the following steps: using Na2CO3 solution whose mass ratio is 0.5% to wash green fruit or rejected fruit, using milling machine to mill green fruit or rejected fruit to obtain oil and water mixture, filtering and separating oil layer from water layer; pulverizing the residual fruit or pomelo fruit peel to 2-3mm, regulating pH value to 1-2, heating for 0.5-1.5hr at 85deg.C so as to obtain pectin solution; filtering pectin solution by using filter cloth, separating filtrate by using inorganic ceramic membrane, concentrating, adding proper quantity of distilled water to wash pectin concentrate to make its pH value be 2.6-3; spray-drying pectin concentrate directly to obtain powdered pectin product; making penetrating solution obtained after membrane separation be passed through macroporous adsorbing resin to recover pomelo flavone; then utilizing residue to make fermentation, adding nitrogen, phosphorus and potassium inorganic fertilizer to prepare organic-inorganic composite fertilizer.

Description

technical field [0001] The invention relates to a processing technology for comprehensive utilization of pomelo green fruit, secondary fruit and pericarp. Background technique [0002] Pomelo is not only large in size, thin in skin, tender in flesh, less in core, moderate in sweetness and acidity, rich in nutrition, and high in medicinal value, but also has rich and fragrant leaves, peels, and flesh, and is known as the "king of fruits". Pomelo is rich in naringin, hesperidin, naringin, vitamins B1, B2, C, sugar, protein, crude fiber, niacin, calcium, phosphorus, iron, carbohydrates and other substances. The pomelo is full of treasures, biological development, full fruit utilization, significant economic benefits, and a very broad market prospect. However, pomelo fruits account for about 25% of the total pomelo production. These products are difficult to sell and the price is very low. The market circulation not only has poor economic benefits, but also has a negative impac...
