Abstract

The invention relates to a processing technology for improving the lycopene content in a tomato product, which comprises the following steps that: the synthesized quantity of lycopene in tomato homogenate is improved; at the atmospheric temperature, the cherry tomato fruit at the firm ripe stage is capped, washed and juiced, the juice is collected, and citrus peels inside a juicer filter is mixed with the juice after being minced so as to obtain the tomato homogenate. 3.0 percent of glucose and 2.5 percent of sodium glutamate are added into the tomato homogenate to be processed for 60 minutes at a constant temperature of 25 DEG C. Different tomato products with high lycopene content can be prepared by adopting the processed tomato homogenate as raw material. (1) The lycopene content in tomato ketchup which is prepared by the processed tomato homogenate is improved by 39.8 percent, and the production process of the tomato ketchup is: 0.25 percent of carrageenan and 2.0 percent of sucrose are added into the processed tomato homogenate to be heated and concentrated until the content of the solid substances reaches 35 percent, the tomato ketchup is covered and sealed after being canned in a glass bottle to be sterilized in the hot water with the temperature of 95 DEG C for 15 minutes. (2) The lycopene content of the tomato haw sheet prepared by the processed tomato homogenate is improved by 21.4 percent, and the production process of the tomato haw sheet is that: 40 percent of white granulated sugar, 0.1 percent of lemon acid and 4 percent of starch are added into the processed tomato homogenate, the thickness of the sheet is 2 mm, and the haw sheet is baked for 11 hours at the temperature of 60 DEG C.

Description

A kind of processing technology that improves content of lycopene in the tomato fabricated product

Technical field

What the present invention relates to is a kind of processing technology that improves content of lycopene in the tomato fabricated product.

Background technology

Recently studies show that, big molecule such as protein in human senility and excessive radical damage cell membrane and the cell, nucleic acid and cause dysfunction closely related, each cell in the every day human body will be subjected to the attack of 100,000 free radicals, various antioxidases will initiatively be eliminated about 99% damage, but still have the wound about 1000 unfeelingly accumulating, 50 years old the time, nearly 30% protein is destroyed by free radical in the human body according to estimates.So, relevant with aging more than 70 kind of disease such as wrinkle, thrombus, canceration etc. all are under the common influence of different nature-nurtures, the different expression form of problem of the same race, the root of all these diseases is all relevant with the accumulation of free radical in the human body, removes free radical and then can eliminate or postpone the generation of these problems.

The singlet oxygen free radical ( ¹O ₂) be a kind of of free radical, be present in the natural colouring matter in the tamato fruit---lycopene is the cancellation of finding up to now ¹O ₂One of material that ability is the strongest can be prevented developing of multiple oxygen free radical injury diseases such as curing cancers.In western countries, catsup has been flavoring indispensable simply in the daily life at present, and in China, and along with people accept and attempt western diet gradually, the consumption figure of catsup is also rising year by year, and China has become second-biggest-in-the-world catsup producing country.So the tomato fabricated product also is people's one of main paties of lycopene of ingesting, content of lycopene is in the tomato fabricated product routine inspection index most important one simultaneously, and content of lycopene is not up to standard in the tomato fabricated product, can influence list marketing.Therefore, study the processing technology of content of lycopene in the tomato products such as improving catsup, can improve the food ration of lycopene effectively, promote the tomato secondary industry of China.

Tamato fruit is according to the difference of maturity, can be divided into the green mature phase, colour-change period, the half-mature phase, firm ripe stage and full ripe stage five different developmental stages, add man-hour at tamato fruit, quicken to rot for preventing the tamato fruit deliquescing, usually the tamato fruit of selecting to pluck firm ripe stage is processed, therefore the author has attempted adding the new method that cheap food additives improve the lycopene synthetic quantity in the homogenate after the hard ripe fruit making beating of tomato, the method that is different from content of lycopene in the existing raising tomato product, as the selection of raw material tomato kind and maturity, concentrate technologic improvement of mode or the like.

The route of synthesis of lycopene is as follows in tamato fruit:

Isopentenylpyrophosphate (IPP) is first comparatively direct precursor substance in the lycopene route of synthesis, and it is transformed by glucose molecule, and IPP is synthetic to have cytoplasm approach and plastid approach.

The cytoplasm approach is: glucose-→ triose phosphate-→ the acetate coacetylase-→ 3-Hydroxy-3-methylglutaryl CoA A (HMG-CoA)-→ MVA-→ IPP

The plastid approach is: glucose-→ glyceraldehyde 3-phosphate-→ pyruvic acid-→ 1-deoxy-D-xylulose sugar-5-phosphoric acid-→ IPP

Hence one can see that, glucose is the synthetic precursor substance of IPP, it also is the synthetic precursor substance of lycopene, in addition, nitrogen-containing compound such as glycine, alanine, glutamic acid etc., can generate biosynthetic another the precursor substance-pyruvic acid of lycopene behind the deamination, the plastid approach of IPP also needs pyruvic acid simultaneously, so glutamic acid and sodium salt also can influence the biosynthesis of lycopene.

Therefore, the author is a material with the perpendicular ripe fruit of Millennium tomato, studies the two to the biosynthetic influence of lycopene by soaking certain density glucose solution and monosodium glutamate (99.9% sodium glutamate) solution, and the result is as shown in table 1.

The influence of table 1 glucose and sodium glutamate

Annotate: the expression mode of peak area is: mean+SD

As shown in Table 1, glucose can improve the content of lycopene by the synthetic quantity that improves the synthetic precursor substance phytoene of lycopene, sodium glutamate also has the effect that improves the synthetic precursor substance of lycopene, but as known from Table 1, the effect of the accumulation of the synthetic promotion lycopene of its inhibition beta carotene is more obvious.Therefore, the author has selected the in earlier stage common processing technology of different types of tomato fabricated product---and the tomato making beating is prepared into tomato homogenate, and be material with tomato homogenate, by adding edible safety, cheap glucose, monosodium glutamate improve lycopene synthetic quantity in the tomato homogenate, and then produce the tomato fabricated product of high hycopene content.

Summary of the invention

The technical problem to be solved in the present invention is to adopt the method for adding the food additives of cheap safety in tomato homogenate to improve the synthetic quantity of lycopene, produces the tomato processed goods of high hycopene content, and this method has characteristics such as technology is simple, small investment.

Technical scheme of the present invention comprises the steps:

At normal temperatures, firm ripe stage holy girl fruit tamato fruit is removed the base of a fruit, cleans, squeeze the juice and collect fruit juice, admix after then the skin slag in the juice extractor filter being minced and obtain tomato homogenate in the fruit juice.In tomato homogenate, add glucose 3.0%, sodium glutamate 2.5%, 25 ℃ of following constant temperature are handled 60min, synthetic quantity with lycopene in the homogenate of further raising tomato, and be raw material with the tomato homogenate after handling, produce the common tomato fabricated products such as catsup, tomato haw sheet of high hycopene content.
