Embodiment Construction

[0033] Collect eight to nine ripe jackfruit fruits, weigh 35kg, accelerate ripening with ethephon, and pulverize as a whole with a refiner, including pulverizing the seeds into 40 to 60 mesh powder, making pulp to obtain 34.36kg, and measuring the juice sag to be 14, Add 130g of sodium metabisulfite to inhibit the consumption of sugar during processing, place it at room temperature for 3 hours, add 15g of pectinase, raise the temperature to 45°C for 130 minutes, then add 1,000 units of high-temperature-resistant α-amylase, and heat to 95°C and cook for 30 minutes. Squeeze to obtain 4.5kg of slag with a water content of 45%, and 29.4kg of sugar juice with a sag of 19. Get the sugar juice and cool it naturally to 40°C, add 0.17kg of alcoholic yeast, and ferment for 15 hours. The measured juice sag is stable at 1.3, and the alcohol content is 8.9%. The fermented liquid was directly distilled to obtain 6.60 kg of 42% (v / v) crude wine and 17 kg of mash. Crude alcohol distillation...

Abstract

The invention provides a method for industrially treating a jack fruit, which uses the jack fruit as a raw material to prepare fuel ethanol and dried distiller grains with solubles. The method comprises the steps of pulping, degrading pectin, saccharifying, separating juice and dreg, fermenting and the like so as to finally obtain high-purity fuel ethanol and high quality dried distiller grains with solubles. The industrially treating method can convert the jack fruit as an industrial raw material into the fuel ethanol and the feed, greatly improves the value added space for the jack fruit, and can promote development of the jack fruit industry, and increase income for peasants.

Description

technical field [0001] The invention relates to a processing method of the tropical fruit jackfruit, in particular to an industrialized processing method for preparing the jackfruit into fuel ethanol and distiller's grain protein feed. Background technique [0002] Jackfruit, also known as woody pineapple, is a high-sugar tropical fruit. It is suitable for planting in tropical regions of my country, such as Hainan, Guangxi, Xishuangbanna, Yunnan, etc., and is a high-yield crop. The new varieties introduced from Malaysia in recent years have a yield of 150 to 250 kilograms per plant and 3 to 5 tons per mu. It is a good variety to increase farmers' income. However, due to the difficulty in opening up the fresh fruit market and the inability to scale up deep processing, it is difficult for the jackfruit industry to drive farmers to become rich. In the past, the processing methods of jackfruit mainly include candied fruit, dried slices, fruit juice, wine making, etc., and its p...
