Problems solved by technology

The main disadvantages of this process include: (1) The oil content of sunflower seeds is very high, and the protein in the prepared beverage is easy to precipitate. The traditional process generally has problems such as flocculation, oil slick, water precipitation, and precipitation; (2) In order to avoid Precipitation and stratification, the traditional process needs to add a large amount of emulsifiers and stabilizers, long-term consumption is not good for health; (3) sunflower protein mostly exists as globular protein, which affects the full absorption and utilization of protein, which cannot be solved by traditional processes; ( 4) The chlorogenic acid in sunflower seeds is easily oxidized to quinone, which makes the sunflower protein product dark green, but it is difficult to remove chlorogenic acid by traditional techniques

Embodiment 1

[0029] Example 1: Preparation of sunflower pulp

[0030] (1) Peeling and crushing of sunflower seeds: Weigh 50kg of peeled sunflower seeds and crush them into 12-mesh samples. After crushing, the particles smaller than 1.70mm in the sunflower seeds account for 70%; (2) Deoiling of sunflower seeds: set CO 2 The pressure of the separation tank I of the supercritical extraction machine is 7-8MPa, and the temperature is 60°C; the pressure of the separation tank II is 4-6MPa, and the temperature is 35°C. Put the crushed sunflower seeds into the extraction tank for extraction, set the extraction pressure to 35MPa, the extraction temperature to 35°C, CO 2 The flow rate is 25kg / h, and the extraction is 60min. The oil remaining in the sunflower seeds after extraction is the original 10% mass ratio; (3) add water and grind: take out the sunflower seeds that have been removed from the oil and place them in a stainless steel bucket, add 4 times the amount of peeled sunflower seeds Weight...

Embodiment 2

[0031] Embodiment 2: preparation contains the sunflower seed vegetable protein drink of hawthorn fruit juice

[0032] Take 50kg of fresh hawthorn, moderately crush it, put it into a stainless steel bucket, add 10 times of water, add liquid pectinase at 40°C and incubate for 6 hours, filter to remove residue, clarify at room temperature, and take the supernatant as fruit juice for production.

[0033] The sunflower pulp obtained in Example 1 was placed in a stainless steel tank with a stirrer, and then 10kg of hawthorn fruit juice was added to the sunflower pulp obtained in Example 1, stirred with a stirrer to make it fully mixed. Add 2 kg of sucrose and 0.2 kg of citric acid into the mixture to fully dissolve, adjust the pH value to about 4.0, perform secondary homogenization at a pressure of 40 MPa and a temperature of 40° C., and make a sunflower seed vegetable protein beverage. The sunflower seed vegetable protein beverage prepared above is heated to 80° C., enters a degass...

Embodiment 3

[0035] Example 3: Preparation of sunflower pulp

[0036] (1) Sunflower seeds are peeled and crushed: take 50 kg of peeled sunflower seeds and crush them into 12 mesh samples. After crushing, the particles less than 1.70 mm in the sunflower seeds account for 80%; The seeds are put into the extractor for extraction, the solvent used is n-hexane, the extraction temperature is set at 60° C., and the extraction time is 3 hours. After extraction, the oil remaining in the sunflower seeds is the original 12% (mass ratio); (3) Add water and grind Take out the sunflower seeds that remove grease and place in stainless steel barrel, add 5 times of weight water (250kg), water temperature 40 ℃, with beater material is pulverized, then cross colloid mill twice, make sunflower seed puree; (4 )Compound enzyme treatment: Put the sunflower seed puree into a stainless steel double-layer pot, add 50g of protease and 25g of cellulase for enzymolysis, the enzymolysis temperature is 40°C, the enzymol...

Abstract

The invention provides a making method of sunflower seed pulp, which includes the steps: firstly, crushing sunflower seeds; secondly, deoiling the sunflower seeds until the oil content of each sunflower seed is reduced by 60-90%; thirdly, adding water and grinding the seeds into stock pulp; and fourthly, treating with compound enzymes. The invention further provides plant protein beverage containing the sunflower seed pulp and a making method thereof. The beverage comprises the sunflower seed pulp and fruit juice in a mass ratio of 1:0.03-0.07 and is 3.9-4.2 in pH value. Most of oil in the sunflower seeds is removed by CO2 (carbon dioxide) supercritical fluid extraction or normal hexane leaching. Spheroproteins are hydrolyzed into small molecular amino acids easy to absorb and use by compound enzymolysis and liquefaction, and cellulase can be used to effectively remove chlorogenic acid in the sunflower seeds, so that color and taste of the beverage are guaranteed. By adjusting the pH value of the beverage, isoelectric points of proteins are avoided, and stability of the beverage is guaranteed.

Description

technical field [0001] The invention belongs to the field of beverages, and specifically relates to a method for preparing sunflower seed pulp, a vegetable protein beverage containing sunflower seed pulp and a preparation method thereof. Background technique [0002] Sunflower seeds, also known as sunflower seeds, are an oil crop with the second largest output in the world. It is rich in protein, containing 21%-30% protein, a wide variety of amino acids, 11 kinds of essential amino acids are complete, and the ratio is reasonable. In addition, it is also rich in oil, dietary fiber, vitamins and trace minerals. For a long time, sunflower seeds have only been used for oil extraction, making snacks and oil-bearing foods, and their proteins and sugars have not been fully utilized. In recent years, with the development of new protein foods, people have realized that sunflower seeds are an important source of plant protein one. (Modern Food Science and Technology, 27: 196-198, 20...
