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.

Example Embodiment

[0021] Example 1

[0022] A method for producing debittered grapefruit peel includes the following steps:

[0023] (1) Weigh 100kg of grapefruit, then wash the fruit, remove the rotten parts, and then separate the pulp and skin, wash the skin, and get about 40kg of washed skin.

[0024] (2) Cut the cleaned grapefruit peel into small pieces of 3~5cm long, 1~1.5cm wide and 2~3mm thick to retain the white flesh;

[0025] (3) Prepare a 5% white granulated sugar solution by mass volume concentration;

[0026] (4) Weigh 120kg of white granulated sugar solution in step (3), boil it, add 40kg of finely cut grapefruit peel, stir and heat to 95℃, keep it for 10min for sterilization, the sterilized grapefruit peel block Under aseptic conditions, cool to below 37℃;

[0027] (5) Add Lactobacillus plantarum to the cooled pomelo peel white granulated sugar solution, the amount added is based on the total mass of the pomelo peel white granulated sugar solution, the number of viable bacteria is 10 7 cfu/g, stir evenly, ferment and culture at 37°C for 24h, heat up to 90°C, keep for 40min, sterilize, cool, remove the grapefruit skin block and drain it to obtain debittered grapefruit skin block. The prepared grapefruit skin block basically removes the bitterness of the grapefruit peel, and has moderate sourness, mellow and sweetness.

[0029] A method for producing debittered grapefruit peel includes the following steps:

[0030] (1) Weigh 100kg of grapefruit, then wash the fruit, remove the rotten parts, and then separate the pulp and skin, wash the skin, and get about 40kg of washed skin.

[0031] (2) Cut the cleaned grapefruit peel into small pieces of 3~5cm long, 1~1.5cm wide and 2~3mm thick to retain the white flesh;

[0032] (3) Prepare a glucose solution with a mass volume concentration of 20%;

[0033] (4) Weigh 200kg of white sugar solution from step (3), boil it, add 40kg of finely sliced grapefruit peel, stir and heat to 100°C, keep it for 5min to sterilize, the sterilized grapefruit peel block white sugar Under aseptic conditions, cool to below 37℃;

[0034] (5) Add Lactobacillus acidophilus to the cooled pomelo peel white granulated sugar solution, the amount added is calculated based on the total mass of the pomelo peel white granulated sugar solution, the number of viable bacteria is 10 5 cfu/g, after stirring evenly, fermentation and culture at 37°C for 72h, warming to 95°C, holding for 30min, sterilizing, cooling, removing the grapefruit skin pieces and draining them to obtain debittered grapefruit skin pieces. The prepared grapefruit skin block basically removes the bitterness of the grapefruit peel, and has moderate sourness, mellow and sweetness.

[0038] (2) Cut the cleaned grapefruit peel into small pieces of 3~5cm long, 1~1.5cm wide and 2~3mm thick to retain the white flesh;

[0039] (3) Prepare a lactose solution with a mass volume concentration of 10%;

[0040] (4) Weigh 160 kg of white sugar solution from step (3), boil it, add 40 kg of finely sliced grapefruit peel, stir and heat to 98°C, keep for 7 minutes for sterilization, and the sterilized grapefruit peel block white sugar Under aseptic conditions, cool to below 37℃;

[0041] (5) Add Lactobacillus casei into the cooled pomelo peel white granulated sugar solution, the amount added is calculated based on the total mass of the pomelo peel white granulated sugar solution, the number of viable bacteria is 10 6 cfu/g, after stirring evenly, fermentation and cultivation at 37°C for 48h, warming to 93°C, holding for 35min, sterilizing, cooling, removing the grapefruit skin pieces and draining them to obtain debittered grapefruit skin pieces. The prepared grapefruit skin block basically removes the bitterness of the grapefruit peel, and has moderate sourness, mellow and sweetness.
