Embodiment 1

[0040] Embodiment 1, the preparation of pumpkin seed cake premix powder

[0041] (1) Select high-quality pumpkin seeds, and after winnowing and magnetic separation to remove impurities, wash them with water to make them reach edible standards.

[0042] (2) The cleaned pumpkin seeds are roasted in an electric heating rotary frying pan at a temperature of 200°C for 5 minutes, and the feeding amount is 2Kg.

[0043] (3) Use a screw-type oil press for oil extraction, the oil extraction temperature is 120°C, the number of pressings is 2 times, and the residual oil rate is lower than 8%. The pumpkin seed oil obtained by this method of oil extraction is of good quality and does not need to be refined edible.

[0044] (4) Supercritical carbon dioxide fluid extraction removes impurities from the pumpkin seed meal. The extraction temperature is 40° C., the pressure is 25 MPa, the flow rate is 20 L / h, and the residual oil rate is 1%.

[0045] (5) Superfine crushing: the crushing time i...

Embodiment 2

[0050] Embodiment 2, the preparation of pumpkin seed bread premix powder

[0051] (1) Select high-quality pumpkin seeds, and after winnowing and magnetic separation to remove impurities, wash them with water to make them reach edible standards.

[0052] (2) Use a hydraulic oil press to extract the oil, the pressure is 60MPa, and the residual oil rate is about 5%. The pumpkin seed oil obtained by this method is of good quality and can be eaten without refining.

[0053] (3) Superfine crushing: the crushing time is 3 minutes, and the particle size of the crushed material is about 200 mesh.

[0054] (4) Twin-screw extrusion processing: add corn flour to mix and extrude, wherein the mass ratio of pumpkin seed meal to corn flour is 10:1, the particle size of corn flour is 200 mesh to 300 mesh, and the extrusion temperature is 130 ℃, pressure 8MPa, screw speed 280r / min.

[0055] (5) Low-temperature drying and crushing: the temperature of the blast dryer is 60° C., and the moisture...

Embodiment 3

[0058] Embodiment 3: Production of pumpkin seed biscuit premix powder

[0059] (1) Select high-quality pumpkin seeds, and after winnowing and magnetic separation to remove impurities, wash them with water to make them reach edible standards.

[0060] (2) Roast the cleaned pumpkin seeds in an electric heating rotary frying pan at a temperature of 200° C. for 5 minutes.

[0061] (3) Use a hydraulic oil press to press the oil, the pressure is 60MPa, and the residual oil rate is about 5%.

[0062] (4) Superfine crushing: the crushing time is 5 minutes, and the particle size of the crushed material is about 300 mesh.

[0063] (5) Twin-screw extrusion processing: add corn flour to mix and extrude, wherein the mass ratio of pumpkin seed meal to corn flour is 8:1, the particle size of corn flour is 200 mesh to 300 mesh, and the extrusion temperature is 150 °C, pressure 5MPa, screw speed 280r / min.

[0064] (6) Drying and crushing: the temperature of the blast dryer is 105°C, the moi...

Abstract

The invention discloses a preparation method of a pumpkin-seed premix-powder base material for baked product, and belongs to the technical field of food processing. The preparation method of the pumpkin-seed premix-powder base material for the baked product comprises the following nine major steps of performing pretreatment on pumpkin seeds, carrying out roasting, carrying out oil extraction, removing impurities from skimmed pumpkin seed meal, carrying out ultra-fine crushing, carrying out extrusion by performing dual twin-screw extruding, carrying out drying and crushing, adding auxiliary materials, as well as carrying out packaging. By performing supercritical carbon dioxide extraction on the pumpkin seed meal according to the preparation method, heterozygous peculiar odor, residual grease and fat-soluble pigments contained in the pumpkin seed meal can be effectively removed; and thus, sensory quality and shelf lives of the baked products prepared from the pumpkin-seed premix-powder base material can be significantly improved. Moreover, ultra-fine crushing and extrusion by performing dual twin-screw extruding are performed on the pumpkin seed meal so that soluble dietary fiber content and protein solubility are improved so as to further increase absorption and digestion rates, as well as processing performance, of the pumpkin-seed premix-powder base material for the baked product; and thus, the baked products produced by using the pumpkin-seed premix-powder base material for the baked product are good in sensory quality, free of taste of gravel, free of speckle, as well as fine and smooth in taste. The pumpkin-seed premix powder for the baked product enriches types of baked products on the market; moreover, the skimmed pumpkin seeds are used for food production so that added values of the pumpkin seeds are increased.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of a pumpkin seed baked product premix powder base material. Background technique [0002] Defatted pumpkin seeds are rich in nutrition, contain high-quality dietary fiber, have a protein content of more than 40%, and have a comprehensive amino acid composition. They are a high-quality plant protein resource with high food safety and do not contain harmful substances. In recent years, as the nutritional function of pumpkin seed oil has been recognized, the sales of pumpkin seed oil have continued to rise, and large-scale planting has begun across the country. Pumpkin seed meal, a by-product of pumpkin seed oil, has a huge output. At present, pumpkin seed meal is mainly used as animal feed or plant fertilizer, with low added value. The focus of research on pumpkin seed meal in China is mainly to prepare protein isolates and polypeptides. T...
