Description

The processing method that no seed lemon eats piece

Technical field：

The present invention relates to garden stuff processing field, more particularly to be a kind of processing method that no seed lemon eats piece.

Background technology：

Citron fruit Vitamin C content is in more than 50mg/100ml, especially pericarp, and Vitamin C content is in 100mg/ More than 100g is that one of more and cheap natural complex C storages of vitamin are rich in Common Fruits, and in lemon peel Some important vitamin contents are that other fruit difficulties are unmatch, such as citrin, and content reaches 1.2mg/ in lemon peel More than 100g is 5~6 times of citrus.Meanwhile lemon is also rich in the human bodies such as VE, VB, creatine and calcium, phosphorus, iron, potassium, sodium, magnesium Required trace element.Have centainly to a variety of diseases such as hypertension, heart disease, cardiovascula arteriosclerosis, canker sore, scurvy Prevention and auxiliary therapeutic action:Although lemon pleasing appearance, fruity is pure and fresh, and quality is superior, since citron fruit is rich in lemon Lemon bitter principle and rich in up to 7% citric acid, so people desire to eat fragrant but also good-looking Lemon fruit not only, but by high bitter peracid Taste is kept off outside the tip of the tongue and lips and teeth of people.

The content of the invention：

Lemon is not only bitter but also the sense of taste of acid the purpose of the invention is to changing, and provides that a kind of best to retain lemon natural Pure ingredient, flavor and sense organ, taste is sour-sweet moderate, in good taste, facilitates storage, carrying, use, and instant bagged can also steep The processing method that piece is eaten without seed lemon without seed lemon tablet after infusing on behalf of the tea.

The present invention is achieved like this:

The processing method that the present invention eats piece without seed lemon, comprises the following steps：

1）Select fruit:Select without seed lemon fresh fruit, this lemon be it is outstanding make every effort to overcome strain on the basis of, process and R＆D institution Cooperation is special for many years to cultivate and has started a kind of no seed lemon of scale result, select Lemon fruit fruit transverse diameter for 40mm- 65mm fresh fruits make raw material, are used convenient for packaging；Why to cultivate and especially select this no seed lemon, be because in Lemon fruit Limonin more than 80% be all distributed in seed and lemon epidermis in fruit, if with there is seed lemon, necessarily bring very heavy bitter taste, cut To every removal seed after piece, it is clear that first, workload is too big, it is difficult to realize mechanical mass production.Second is that go out after removing seed Existing seed position cavity destroys the full shape of chankings entirety.Could only meet without seed lemon tablet make not only it is nice but also good-looking, Saving of labor, water-saving mechanization production again；

2）Wash fruit:It carries out washing fruit under room temperature at 0 DEG C -30 DEG C:It washes Guo Shui and reaches city tap-water standard, fruit leads to It crosses bubble and pond progress pressure pulse cleaning occurs, then carry out banister brush water drenching rolling again and wash, so as to reach process sanitary standard；

3）Sterilizing：Lemon fruit is 3mg -5mg/L through concentration, and continuous flow is 1t -1.5t/h ozone water sterilizations, and the time is 4min -10min, by sterilizing and the sanitary control of rear process, to ensure product safety health in process of producing product；

4）Grind skin：Fruit face surface layer is ground off by milling drum:Full fruit Even Grinding peel thickness 0.1mm -0.2mm, deionization The pericarp under grinding is removed in water leaching, makees other purposes after water, slag mixture are collected, is ground the effect of peeling because of in lemon Bitter principle ingredient first is seed content height, and the bitter principle of epidermis contains with regard to number second.Besides due to heavy metals such as leaded gas and oil floating dusts Fruit face is enriched in pesticide residue, and cleaning is clear, and very difficult (present inventor once samples the fruit such as lemon mostly inspection side, Confirmation has that several times are exceeded, and using fruit face as enrichment positions), remove the pericarp of pole book by grinding, ensure that product is up to standard, eat Safety.Third, existing mill fruit machine is that fruit is carried out high speed collision, aculeus type to grind deeply, after grinding skin, pulp structure is hit by machinery Bad, fruit softening is broken up, has been unable to meet the fruit type requirement of processing high grade chankings, the present invention goes to pole for the grinding of single fruit relative quiescent Sake layer, on fruit structure and hardness without influence, chip formation is ensured；

5）Transverse diameter tangential section, every thickness 4mm -6mm:Through many experiments and market survey, determine in the present invention outside to chankings Footpath and thickness physical dimension, chankings decorative pattern is beautiful, beneficial to processing, convenient for edible；

6）It is quenched：Lemon tablet is immersed in 10h in quenched solution-quenched for 24 hours, it is quenched after the intensity of fruit pulp and soft Toughness is improved, and is processed beneficial to rear process, reduces acidity, improves mouthfeel, by mass percentage have sodium chloride in quenched solution 0.1-0.3%, calcium chloride 0.05-0.1%, sodium sulfite 0.1-0.3%, deionized water surplus；

7）Lemon tablet is washed with deionized water only afterwards, by 90 DEG C -98 DEG C of deionized water blanching 2min -4min enzyme deactivations；

8) first time vacuum sugar infiltration：Chankings is put into mixed once liquid, through excess pressure be 200Pa, the time for 15h- The vacuum sugar infiltration of 20h has D-different Vc to receive 0.1-0.2% by mass percentage, in mixed once liquid, citric acid 0.2-0.25%, Sucrose or xylitol 25-50%, deionized water surplus；

9）Second of vacuum sugar infiltration：After vacuum pumping, then chankings is put into 10-15KPa of vacuum degree in secondary mixed liquor, oozed Sugared 8h-12h has sucrose and/or xylitol 15-50%, honey 3-7%, deionization by mass percentage, in secondary mixed liquor Water surplus；

10) chankings moisture drying to 20-25% is made it easier into storage and packaging operation in≤70 DEG C of environment；

11) vacuum sealed package is carried out in units of piece with food-grade high barrier film bags under hundred grades of gnotobasis；

12) weigh mounted box, plastic packaging by quality requirement, obtain warehousing finished products.Process control and product quality reach country's Qs certifications With international HACCP, GMP standard.

In above-mentioned method by weight percentage, in mixed once liquid also have fruit syrup 15-25%, by quality percentage Than there is fruit syrup 15-25% in, secondary mixed liquor.

The present invention is easy to operate, and can realize serialization mechanization production, and realizing lemon chankings can be instant, can be with Infusion is used on behalf of the tea, and product acid is comfortable to work as, in good taste, and storage carries, is easy to use, can also match somebody with somebody by adjusting sugared ingredient is oozed Side, instead of sucrose, wishes control volume severe one, diabetic, old age with xylitol and other plant sweetener to meet The needs of the special populations such as people.And production process sanitation and hygiene, product quality reach national and foreign standards, and market prospects are extremely seen It is good.
