Embodiment 1

[0036] Embodiment 1: (extract from tomato, prepare lycopene)

[0037] Weigh 100kg of mature tomatoes without disease or damage, wash the surface with water; rinse with hot water at 90°C for 6 minutes, then quickly rinse with cold water at 20°C for 4 minutes, and complete the peeling with the assistance of mechanical rolling and hydraulic impact; cut the peeled tomatoes into two rings Half, manually complete the seed removal; the pulp is mechanically crushed and then pulped with a beating mechanism; the pulp is packed into a 150-mesh polyester sieve silk extraction bag 3, tied, and the filtrate 1 is separated by -30Kpa negative pressure suction filtration (can be used for processing fruit juice or beverage), retain 20kg of jam 1 in the extraction bag 3; put the extraction bag 3 containing jam 1 into the extraction tank 2-1, add 200L of 80% ethanol aqueous solution to the tank, and ultrasonically 1 treatment for 4 minutes, take out the extraction bag 3 from the extraction tank 2...

Embodiment 2

[0038] Embodiment 2: (extracting and preparing lycopene from watermelon)

[0039] Weigh 100kg of disease-free, non-damaged, mature red watermelon pulp, make pulp and put it into 200-mesh nylon sieve silk extraction bag 3; after negative pressure filtration at -20Kpa, put the remaining jam 1 (22kg) into extraction bag 3 Put it into the extraction tank 2-1, add 250L of 70% ethanol aqueous solution to the extraction tank 2-1, extract it with ultrasonic wave 1 at 80°C and 50KHz for 2min, and after it is separated by negative pressure suction filtration at -55Kpa, keep the jam 2 in the extraction bag 3 ;Jam 2 was repeatedly extracted and filtered once in the same way to obtain 15kg of jam 3; the extraction bag 3 containing jam 3 was placed in the extraction tank 2-2, and 400L tetrahydrofuran was added to the extraction tank 2-2 at 50°C and 50KHz Under the condition of ultrasonic 1 extraction for 2 minutes, and then -60Kpa negative pressure suction filtration to separate the sauce r...

Embodiment 3

[0040] Embodiment 3: (extract and prepare lycopene from watermelon sauce)

[0041] Weigh 1Kg of watermelon sauce, put it into a 300-mesh nylon sieve silk extraction bag 3, add 40L of diethyl ether, and extract by ultrasonic wave 1 at 30°C and 80KHz for 5min, and the extract is rotatably evaporated at 35°C to obtain a crude crystal, which is then rinsed with ethanol. Wash and dry with nitrogen to prepare about 0.15 g of 76% lycopene crystals. Processes, steps such as the preparation of watermelon sauce, ethanol treatment are the same as embodiment 2.

Abstract

The invention discloses an extraction preparation method of lycopene, belonging to the technical field of food engineering. The method uses tomatoes or watermelon flesh as raw materials and adopts the technology of ultrasonic and extraction bags, which comprises the following steps: (1) the treatment of the raw materials and beating; (2) the separation of solid puree and liquid puree of fruit puree; (3) the ethanol water treatment of jam;(4) the extraction of the lycopene extractant of the jam and (5) the preparation of crystallization products of the lycopene. The extraction time of the invention is reduced to 10 to 60min from the10 to 20h of conventional time, and moreover the purity content of products is obviously improved from 10 to 20 percent in general to 70 to 80 percent. Therefore, the extraction preparation method is characterized by being efficient and fast, being convenient to be operated, low cost, high content of lycopene in the products, etc and is suitable for the promotion and the application in the industrialized and large scale production enterprises of natural lycopene with high purity.

Description

technical field [0001] The invention belongs to the technical field of food engineering, and in particular relates to a method for extracting and preparing natural lycopene by using tomatoes and two melons as raw materials. Background technique [0002] Lycopene is a red fat-soluble multifunctional natural pigment, which mainly exists in ripe tomatoes, watermelons, guavas and other vegetables and fruits. In addition to the pigment function, lycopene also has a strong antioxidant function, which can effectively remove free radicals in the body, prevent cell lesions and cancer, and maintain normal cell metabolism, thereby improving human immunity and delaying human aging. Three highs, cardiovascular and cerebrovascular diseases, prostate diseases, esophageal cancer, lung cancer, breast cancer, uterine cancer, skin cancer and other diseases also have a significant improvement effect. Lycopene has also become a hot spot in the research and development of functional natural pigm...
