Abstract

The invention discloses debitterized shaddock peel and a production method and use thereof. The production method comprises the following steps: (1) separating pulp and peel of shaddock, and chopping the peel; (2) preparing sugar liquor, and boiling the liquor; adding the shaddock peel, stirring and heating to 95-100 DEG C, insulating for 5-10 minutes to sterilize, and then cooling the shaddock peel white granulated sugar liquor in an aseptic condition to below 37 DEG C; and (3) inoculating lactic acid bacteria into the shaddock peel white granulated sugar liquor, uniformly stirring, fermenting and culturing for 24-72 hours at 37 DEG C, heating to 90-95 DEG C below, and insulating for 30-40 minutes to sterilize; cooling; and fishing out the shaddock peel blocks and draining off to obtain the debitterized shaddock peel. The debitterized shaddock peel prepared by the method has the characteristics of moderate sour and mellowness and sweetness, and flavor and taste and the like can satisfy the demand of consumers. Bitterness of shaddock peel is basically removed. The debitterized shaddock peel produced can be used for producing other series of products, such as shaddock preserved fruits, honey shaddock tea, shaddock peel jam and shaddock beverages.

Description

technical field [0001] The invention relates to a debittering pomelo peel, a production method and application thereof. Background technique [0002] The storage resistance and unique flavor of pomelo are unmatched by other fruits, and the suitable area for its cultivation is relatively narrow. Pomelo fruit is of high quality, good flavor, thick skin, and storage-resistant. It has the reputation of "natural canned food". Grapefruit peel contains limonin substances such as naringin and neohesperidin, which can reduce the viscosity of blood circulation and reduce the formation of thrombus. If middle-aged and elderly people suffer from cerebrovascular disease, eating grapefruit often has Helps prevent strokes. [0003] However, it is precisely because the pomelo peel contains limonoids that the processed products of pomelo peel have a bitter taste, and the bitter taste will be stronger after processing, which will affect the taste of the product. The existing debittering met...
