Abstract

The invention provides a process for preparing a health food, in particular to a process for food called fruit vitamin C, which can maintain in most degree the vitamin C and other nutriment in fruit and is convenient for carry, preservation and edible. The invention comprises the following steps: peeling and kernel removing the fruit, juice extracting, vacuum condensing the juice in vacuum condensing tank under low temperature, adding various findings, stirring and granulating, drying with micro oven, pelleting, checking, packing and getting the product.

Description

A kind of production method of fruit vitamin c

Technical field

The present invention relates to a kind of production method of health food-Yizhibao, relate in particular to a kind of production method of health food-Yizhibao that is called as fruit vitamin c.

Background technology

The a variety of health foods that contain fruit nutrition composition (mainly being vitamin C, micro-B1, B6, tartaric acid, iron etc.) are arranged in the market, and what aqua was wherein arranged also has a tablet.Traditional aqua health food, be by fruit is squeezed, filtration, high-temperature sterilization, can forms then.After its weak point was fruit syrup process high-temperature process, vitamin C destroyed and runs off greatly, and Vit C contents is lower in the product.In addition, because the aqua product volume is big, carry also inconvenient.The tablet health food then is to adopt the method production that adds fruit nutrition composition (vitamin C, vitamin B1, vitamin B6, tartaric acid, iron etc.), its weak point is that its nutrition and mouthfeel are complete not as the fruit juice equilibrium, and can not make full use of abundant natural fruit resource.

Summary of the invention

The present invention has overcome the deficiency on the prior art, provide a kind of and can fully keep natural fruit nutrition, the production method of ascorbic tablet particularly, the fruit vitamin c of producing in this way has the same odor type of natural water fruit juice, carry, take conveniently, preserve (1 year) for a long time.

The present invention is achieved by following technical proposals: will squeeze after natural fruit (for example orange) peeling (shell) stoning (seed); The fruit syrup granularity that squeezing is come out is that the cellulosic filter screen of 300 orders/inch filters; Place vacuum concentration pot under-5-10 ℃ low temperature, to carry out vacuum filtrate and concentrate, when vacuum reaches 2 * 10 ^-1During Pa, close vacuum valve, charge into inert gas (as argon gas) again, make the vacuum tank internal gas pressure reach normal pressure, open tapping valve then, take out low amounts of water fruit juice and carry out the enrichment inspection; Enrichment control: water content is between 12-15%; Press the ratio of inspissated juice 50-60% (weight ratio, down together), fructose 4-6%, glucose 28-34%, edible calcium carbonate 4-6%, dextrin 3-5% then, add above-mentioned auxiliary material, mixing and stirring, and carry out wet granulation; The particle made is carried out compressing tablet after carrying out dry 50-60 minute with microwave under 38 ℃ of-42 ℃ of temperature; Qualified through composition and Bacteria Detection, product.

Beneficial effect of the present invention: the fruit vitamin c of producing with the present invention is to adopt China's abundant and cheap fruit (as orange, hawthorn, Chinese gooseberry etc.) is primary raw material, concentrate through squeezing, filtration, vacuum, add an amount of auxiliary material (as fructose, glucose etc.) then, through low temperature drying, compressing tablet and the homovitamin C health food of making of new generation.This novel healthy food since in manufacturing process, avoided traditional fruit drink must through the high-temperature process link, most of vitamin C in the fruit is able to intact preservation and gets off, product natural complex C content height, and most nutriments in the natural fruit have been kept, as vitamin B1, B6, tartaric acid, iron etc. to the human body beneficial.Carry, preservation, instant, be a kind of natural resources that make full use of, be beneficial to and improve the human quality, be easy to apply, help the innovation and creation of society and economic development.

Specific implementation method

The invention will be further described below in conjunction with example.

Embodiment 1

Fresh orange is removed seed, squeeze the juice then; Cellulosic filter screen (two-layer folded mutually) with granularity 300 orders/inch filters fruit juice; Take by weighing about 80 kilograms of orange juice after the above-mentioned filtration, place vacuum concentration pot, carry out vacuum and concentrate under low temperature (3 ℃), making it form water content is 12.5% concentrate; Take by weighing 54 kilograms of above-mentioned concentrates, place the agitated kettle of sealing, add 5 kilograms in fructose, 32 kilograms of glucose, 5 kilograms of edible calcium carbonates, 4 kilograms in dextrin successively, fully stirring is mixed at normal temperatures, carries out wet granulation then; Place microwave dryer under 38-40 ℃ of temperature, to dry 50-60 minute on the particle of making, carry out compressing tablet then; After being cooled to normal temperature, every double centner product is randomly drawed 100 grams, detects by following standard: vitamin C 〉=50 milligram; Calcium 〉=300 milligram; Moisture content≤2000 milligram; Plumbous≤0.1 milligram; Total arsenic≤0.5 milligram; Copper≤10 milligram; Outward appearance: size is consistent, does not get damp, and nothing is gone mouldy, the visible impurity of no naked eyes, free from extraneous odour; Bacterium: total plate count cfu/g≤1500, coliform MPN/100g≤30, pathogenic bacteria (salmonella, Shigella, staphylococcus aureus) must not detect.It is qualified to detect, and this batch product is finished product.

Embodiment 2
