Description

The preparation method of a kind of expanded matrimony vine
Technical field
The present invention relates to the preparation of leisure food, particularly the preparation method of a kind of expanded matrimony vine.
Background technology
Leisure food as the term suggests be after dinner, snacks snack or the cake dessert of leisure between meal, they should be low in calories, delicious food meets appetite and " grinding one's teeth in sleep " pastime between people's meal, is difficult for having enough and affects the pot foods of dinner." bread is the staff of life ", but nowadays people not merely rest on the surface of eating, and become more healthy, leisure more but will allow eat.Under such diet theory, domestic leisure food has obtained development at full speed.Along with the development of leisure food industry and the raising of people's living standard, leisure food starts to press close to people's life, and more people has been placed on the starting point healthy and nutrition aspect.The leisure food production firm in the whole world is publicizing leisure food and can become a part for meals in a healthy and balanced way---and the leisure food of low in calories, low fat, low sugar is the main flow of new product development from now on.Therefore, exploitation health and functional food are by being the leisure food market developing direction in future, and in various leisure food, the product category of dilated food at most, the consumer group is the widest, sales volume is maximum, can account for the more than 50% of leisure food total amount.
Matrimony vine is conventional nutritious tonifying good merchantable brand, cook congee, endure cream at conventional its among the people, steep in wine or same other drug, food edible together.The fruit of Chinese wolfberry is exactly that people top grade supported in nourishing from ancient times, has and prolongs the anti-ageing effect that declines, so have another name called " but I ".Vitamin C content in matrimony vine is higher than orange, and content beta-carotene is higher than carrot, and iron content is also higher than beefsteak, more attracting, and the Yang strengthening function that matrimony vine plays is very powerful.
Matrimony vine is as the good merchantable brand of nourishing of medicine-food two-purpose, its nutritive value and health care are aobvious well known, matrimony vine is prepared into a kind of expanded class leisure food and meets the world completely, the developing direction of domestic leisure food, but according to leisure food " at any time, everywhere, the consumptive characteristics such as arbitrarily ", separately edible matrimony vine also can be because of amount, eating method, edible time, the factor differences such as edible crowd produce some side effects, therefore, best processing mode is exactly the nutrition according to matrimony vine, functional characteristics and other nutrition, healthy food material science is composite, balanced nutritious, to reach the object of science meals.Chinese patent CN102669597B discloses the processing method of a kind of bamboo charcoal matrimony vine, first matrimony vine is carried out to cryogenic vacuum expanded, then use in " bamboo charcoal clothing " on bamboo charcoal mush, by bamboo charcoal powder 3%-30%, starch 5%-40%, maltodextrin 5%-30%, red date powder 5%-20%, oligomeric raffinose 5%-10%, hawthorn powder 2%-5%, honey 1%-5%, Semen sesami nigrum 1%-5%, (percentage is mass percent herein, taking expanded matrimony vine total amount as basic calculation), cross cleaner liquid with cassia seed or chrysanthemum tea water soaking and be made into bamboo charcoal mush; Above-mentioned preparation method's defect is: 1. the matrimony vine water imbibition of after the swelling is extremely strong, in upper " bamboo charcoal clothing " process, easily absorbs water, and has a strong impact on the crisp degree of matrimony vine, even follow-up dry rapidly, also can not recover original fragility; 2. product, from having lost in appearance natural colour and the shape of matrimony vine, has reduced product specification and consumer's appetite; 3. there is dispute in China in bamboo charcoal nutritive value of food, and market prospects are not too optimistic.Chinese patent CN102648758A discloses a kind of method of preparing biological expanded matrimony vine, by matrimony vine cleaning, peeling, cutting, pretreatment, predrying, sam, changing temperature-pressure-difference and puffing, cooling, classification, be packaged to be expanded matrimony vine, in order to make taste better, described method is carried out pretreatment to matrimony vine pulp before being also included in pre-dried, described pre-treatment step is to be to soak 2-4h in 75%-85% sugar container by matrimony vine pulp at quality percentage composition, drain, then remove the liquid glucose on pulp surface with clear water.The defect that above-mentioned preparation method exists is: 1. after matrimony vine being cleaned, remove the peel, cutting, complex process, operates very inconveniently, can not realize scale, suitability for industrialized production; Wolfberry easily run off, oxidizable; 3. finished product is FRUCTUS LYCII grain, and fruit bar or chankings, destroyed the natural shape of FRUCTUS LYCII.
FRUCTUS LYCII is as a kind of special berries fruit, no matter fresh fruit or dry fruit, its pericarp is very thin, easily broken, be difficult for processing, therefore, matrimony vine is processed into and a kind ofly can keeps the expanded class leisure food that raw-food material that its natural fruit particle shape shape and color and luster and other match organically combines to be difficult to from the angle of technology, this is also this area research staff's long-term pursuit.
Summary of the invention
Technical problem solved by the invention is to overcome defect prepared by existing matrimony vine leisure food, taking dried fruit of lycium barbarum as primary raw material, matrimony vine after cleaning is soaked in percolating solution, adopt high-pressure pulse electric and ultrasonic synergistic wall breaking technology to carry out appropriate broken wall to FRUCTUS LYCII grain simultaneously, the composition of percolating solution can enter FRUCTUS LYCII intragranular after broken wall by osmosis, then prepares a kind of nutrition and health care leisure food---expanded matrimony vine that has matrimony vine natural fruit granular shape and color and luster, the equilibrium of nutritional labeling science, is applicable to various crowds through vacuum and low temperature puffing technique.

2. the mensuration of rehydration ratio: sample thief 5g, rehydration container is 300ml beaker, 20 times of water consumptions, i.e. 100ml, floods wherein sample, floods at ambient temperature after 30 minutes, to pull sample out to put bamboo sieve upper, and natural draining 5 minutes, claims to drain heavily,
Rehydration ratio=(quality of the front sample of the quality-rehydration of sample after rehydration)/sample quality.
3. the mensuration of hardness: adopt matter structure instrument (TA, XT2) to measure, get shape, the size consistent sample of trying one's best; Measure matter structure, after taking out rapidly from packaging bag, one by one on matter structure instrument, do compression test, repeats 10 times, finally average, hardness number equals the peak-peak in matter composition, peak number by matter structure software on computer directly several go out.
4. the mensuration of reconstitution rate: reconstitution rate=water suction sample is heavy/first sample weight, condition determination: the sample of same quality is measured in 25 DEG C of rehydration 12min.
Expanded matrimony vine prepared by the embodiment of the present invention 3, common expanded matrimony vine and hot blast raw material matrimony vine carry out the expanded performance parameters such as puffed degree, rehydration ratio, reconstitution rate, hardness to be measured, and result is as table 2:
Table 2 expanded performance parameter detecting result
Project Puffed degree Rehydration ratio Reconstitution rate Hardness (g) Moisture (%)
Expanded matrimony vine 2.887 2.421 2.876 616.5 2
