Abstract

The invention provides a screening method of an optimal process for preparing water insoluble dietary fibers from pineapple fruit residues. The screening method is mainly composed of influence ranges of following influence factors: the mass percent of sodium hydroxide is 1%-5%; the material-liquid ratio ranges from (1:10) to (1:30); the alkaline hydrolysis time is 30-70 minutes; and the temperature is 40-80 DEG C. The additional value of a deeply-processed product can be further improved by a research of the dietary fibers in pineapples and an industrial chain of the machining of the pineapples is prolonged; and meanwhile, the screening method has the extremely profound practical significance on improvement on the health level of people in China.

Description

technical field [0001] The invention relates to a screening method, in particular to a screening method for preparing water-insoluble dietary fiber from pineapple pomace. Background technique [0002] Pineapple (scientific name: Ananas comosus), commonly known as pineapple, is one of the famous tropical fruits. Fujian and Taiwan are called Wangli or Wanglai (), Singapore and Malaysia are called yellow pears, Chaoshan areas are called fanli, and mainland China and Hong Kong are called pineapple. There are more than 70 varieties, one of the four famous fruits in Lingnan. [0003] Pineapples are native to the Amazon River Basin in Brazil and Paraguay in South America, and were introduced to China from Brazil in the 16th century. It has now spread throughout the tropics. The edible part is mainly composed of fleshy enlarged inflorescence rachis and spirally arranged flowers around the periphery. The flowers are usually not firm, and the persistent perianth lobes form a cavity...
