Embodiment 1

[0032] 1. The blueberry pomace after the blueberry juice is crushed by a tissue grinder, and mixed with dry matter and acid ethanol (the volume fraction of ethanol and water is 60%, and the pH value is 1.5) at a mass-to-volume ratio of 1:50 , using ultrasonic-assisted extraction. The ultrasonic power is 350W, the extraction temperature is 35°C, and the extraction time is 45min. The extract is spray-dried to obtain powdery blueberry pomace extract, and the content of anthocyanin in the extract is detected by spectrophotometry. The powdered extract contains 8.66% anthocyanins.

[0033] 2. after the powdery blueberry pomace extract obtained in step 1 is mixed with citric acid and sodium citrate according to the mass ratio of 100:0.65:0.07, then the powdery blueberry pomace extract is mixed with citric acid and sodium citrate The mixture and stevioside are uniformly mixed according to the mass ratio of 100:1.2 to obtain the granule with the effect of lowering blood pressure.

Embodiment 2

[0045] 1. The freeze-dried blueberry pomace is crushed with a plant pulverizer, mixed with dry matter and acid ethanol (the volume fraction of ethanol and water is 60%, and the pH value is 3) with a mass to volume ratio of 1:70, and ultrasonic Assisted extraction. The ultrasonic power is 350W, the extraction temperature is 45°C, and the extraction time is 50min. The extract is concentrated and freeze-dried to obtain powdery blueberry pomace extract, and the content of anthocyanin in the extract is detected by spectrophotometry. The powdered extract contains 8.72% anthocyanins.

[0046] 2. Mix the powdered blueberry pomace extract obtained in step 1 with citric acid and sodium citrate in a mass ratio of 100:0.65:0.07, and then mix it evenly with xylitol in a mass ratio of 1:2 to obtain A granule with the effect of lowering blood pressure.

[0047] 3. Animal experiment: 32 12-week-old male SHR rats, with a body weight of 260±15g, had free access to food and water, kept at an ...

Embodiment 3

[0053] 1. The freeze-dried blueberry pomace is crushed with a plant pulverizer, mixed with dry matter and acid ethanol (the volume fraction of ethanol and water is 60%, and the pH value is 2) with a mass to volume ratio of 1:60, and ultrasonic Assisted extraction. The ultrasonic power is 350W, the extraction temperature is 40°C, and the extraction time is 50min. The extract is concentrated and freeze-dried to obtain powdery blueberry pomace extract, and the content of anthocyanin in the extract is detected by spectrophotometry. The powdered extract contains 8.8% anthocyanins.

[0054] 2. Mix the powdered blueberry pomace extract obtained in step 1 with fruit juice powder in a ratio of 3:7 to obtain a granule with the effect of lowering blood pressure.

[0055] 3. Animal experiment: 32 12-week-old male SHR rats, with a body weight of 260±15g, had free access to food and water, kept at an ambient temperature of (26±1)°C, and a relative humidity of (60±5)%, and were pre-reared ...

Abstract

The invention discloses a preparation method of a blueberry pomace extract product having hypotensive effect and an electuary. The preparation method comprises the following steps: mixing blueberry pomace and acid alcohol, employing ultrasonic-assisted extraction, and drying an extract product to obtain the powdery blueberry pomace extract product containing anthocyanin. The electuary comprises the blueberry pomace extract product, a sour additive and calorie-free sugar, or comprises blueberry pomace extract product and fruit juice powder, the sour additive is a mixture of citric acid and sodium citrate, and calorie-free sugar is stevioside or xylitol. According to the invention, the by-product blueberry pomace extract product produced by a blueberry fruit juice production is used for obtaining the blueberry pomace extract product containing anthocyanin through a reasonable technology, the blueberry pomace extract product has hypertension effect, provides a new approach for using the blueberry pomace, fully uses the blueberry resource, and blueberry processing economic benefit is increased. Simultaneously, the pollution problem due to by-product discharge can be solved, and the method is simple, and the practicality is strong.

Description

technical field [0001] The invention belongs to the field of deep processing of agricultural by-products. More specifically, it relates to a preparation method of blueberry pomace extract with antihypertensive effect, and an infusion drink with antihypertensive effect prepared by using the blueberry pomace extract. Background technique [0002] Hypertension is an important factor causing cardiovascular and cerebrovascular diseases, and nearly 50-60% of the elderly have elevated blood pressure. With the increase of work pressure, the onset population is getting younger and younger, and it is currently recognized as one of the most serious diseases that endanger human health. Hypertension refers to an independent disease whose etiology is not yet clear, and whose main clinical manifestation is systemic arterial systolic or diastolic blood pressure higher than the normal range. It is one of the important risk factors leading to myocardial infarction and cerebrovascular events....
