Embodiment 1

[0023] A preparation method of instant dried pumpkin, comprising the following steps:

[0024] (1) Raw material preparation: wash the old pumpkin, peel and pulp, slice into slices with a thickness of 3-4mm, soak in salt water for 30-40 minutes to obtain pumpkin slices;

[0025] (2) One-time drying: Put the pumpkin slices in an oven and dry at 54°C until the water content is reduced by 20-25%. Spray the soybean oligosaccharide solution on the surface of the pumpkin slices with a mass concentration of 14%. 8% of the weight of the slices, and then dried at 47°C until the water content continued to decrease by 15-20%, so as to increase the strength of the pumpkin slices and avoid soft rot during post-processing, so the pumpkin slices should be dried once;

[0026] (3) Primary fermentation: add lactic acid bacteria to primary dried pumpkin slices, and ferment at 35°C for 3 days to produce rich small molecule nutrients, increase the umami taste and strength of pumpkin slices, promot...

Embodiment 2

[0032] A preparation method of instant dried pumpkin, comprising the following steps:

[0033] (1) Raw material preparation: wash the old pumpkin, peel and pulp, slice into slices with a thickness of 3-4mm, soak in salt water for 30-40 minutes to obtain pumpkin slices;

[0034] (2) One-time drying: Put the pumpkin slices in an oven and dry at 55°C until the water content is reduced by 20-25%. Spray the soybean oligosaccharide solution on the surface of the pumpkin slices with a mass concentration of 15%. 9% of the weight of the slices, and then dried at 48°C until the water content continued to decrease by 15-20%, increasing the strength of the pumpkin slices, avoiding soft rot during post-processing, and drying the pumpkin slices once;

[0035] (3) Primary fermentation: add lactic acid bacteria to primary dried pumpkin slices and ferment at 36°C for 3 days to produce rich small molecule nutrients, increase the umami taste and strength of pumpkin slices, promote gastrointestin...

Embodiment 3

[0041] A preparation method of instant dried pumpkin, comprising the following steps:

[0042] (1) Raw material preparation: wash the old pumpkin, peel and pulp, slice into slices with a thickness of 3-4mm, soak in salt water for 30-40 minutes to obtain pumpkin slices;

[0043] (2) One-time drying: Put the pumpkin slices in an oven and dry at 56°C until the water content is reduced by 20-25%. Spray the soybean oligosaccharide solution on the surface of the pumpkin slices with a mass concentration of 16%. 10% of the weight of the slices, and then dried at 49°C until the water content continued to decrease by 15-20%, increasing the strength of the pumpkin slices, avoiding soft rot during post-processing, and drying the pumpkin slices once;

[0044] (3) Primary fermentation: Add lactic acid bacteria to primary dried pumpkin slices and ferment at 37°C for 4 days to produce rich small molecule nutrients, increase the umami taste and strength of pumpkin slices, and promote gastroint...

Abstract

The invention mainly relates to the technical field of food processing, and discloses a preparation method of instant dried pumpkin. The method comprises raw material preparation, primary drying, primary fermentation, secondary fermentation, secondary drying, seasoning, and drying; the method is simple, and the obtained dried pumpkin is golden in color, rich in aroma, is soft, tough and chewy, increases deep processed products of pumpkin on the market, does not contain any additives, is safe and healthy, and meets needs of consumers for nutrition and taste; old pumpkin is dried once after washing and slicing to reduce part of moisture, a soy oligosaccharide solution is sprayed, then pumpkin slices are continued to dry to increase the strength of the pumpkin slices to avoid soft and mashedpumpkin in the post-processing; after the primary drying, lactic acid bacteria is inoculated for the primary fermentation to produce rich small molecule nutrients, increase the fresh taste and strength of the pumpkin slices and promote gastrointestinal functions; after adding of a seasoning A, short-term secondary fermentation is performed, the flavor of the pumpkin slices is enriched, consumer appetite is increased; and after the secondary fermentation, low temperature secondary drying is performed, so that the taste is more tough and chewy.
