Description
Technical field
The invention belongs to food processing technology field, be specifically related to a kind of method that fruit jelly sulphur is hidden sulfur dioxide residue in the raw material that reduces.
Background technology
Food industry is the pillar industry that the national economy meta ranks first.In numerous food processing product, all kinds of traditional foods occupy a tiny space in food processing with they characteristics separately, play a part to intersperse people's dietetic life.As preserved fruit preserved fruit, fruit jelly etc., be pot foods and the characteristic typical local food that the consumer likes.Yet from product quality supervision check result and consumer's reflection in recent years, the quality safety of traditional food exists many problems, has become the hot issue that food quality safety is watched attentively, and wherein content of sulfur dioxide severe overweight problem is particularly outstanding.Fruit jelly processing is compared with other food processing, and bigger difference and special process are arranged.Longer between the preservation term of first fruit jelly raw material, process from raw material post processing to the product of gathering, usually to place 3～6 months or the longer time, for improving the keeping quality of preserving raw material, except that making salt embryo, fruit embryo through the stifling preservation of sulfur dioxide, salt down the way that the sulfite solution immersion is adopted in the preservation of soaking material more; It two is work in-processes, often needs to use sulphite as decolorizer.The covet aesthetic appearance of keeping quality and product of some producers often adds excessive sodium pyrosulfite in the production, caused the content of sulfur dioxide severe overweight of finished product, to the healthy formation harm of consumer, and becomes the underproof one of the main reasons of product.According to " the GB14884-2003 preserved fruit sanitary standard " requirement that replenishes revision, sulfur dioxide residual quantity can not surpass 0.35g/kg in the fruit jelly.Guangdong-style preserved fruits sulphur is hidden desulfurization of raw material and is handled the method that generally adopts the clear water rinsing at present, because the time that sulphur is hidden is longer, sulphite fully infiltrates in the fruits and vegetables tissue, combine closely with multiple organic matter in the fruits and vegetables, the fruit and vegetable materials that in addition has dense structure after calcification processing, only adopt the method for clear water rinsing, rinsing needs long period time, to production efficiency, fruits and vegetables tissue etc. has certain influence, and the effect of removing sulphite is limited, many products still do not reach standard-required, and sulfur dioxide residual quantity exceeds standard becomes the critical control link of Guangdong-style preserved fruits safety in production.
For improving desulfurization degree, enterprise that has and research department have carried out some researchs to the method that desulfurization is handled, the way of vacuum desulfurization has been proposed to adopt as the emerging enterprise in east, Beijing City Nutrient Source Inst food industry technique center, compare with simple infusion method, improved desulfurized effect to a certain extent and be significantly improved; Really embryo, olive, ginger etc. are experiment material to Foodstuffs Academy associate professor Huang Wei of Agricultural University Of South China with dried hawthorn embryo, plum through the sodium pyrosulfite processing, adopt distinct methods such as alkali lye, hydrogenperoxide steam generator immersion, ultrasonic wave processing, carry out desulfurization and handled research, the result shows and utilizes ultrasonic wave and dipping by lye or clear water to soak the method that combines, and can remove most of sulfur dioxide in the raw material within a short period of time.But not seeing has the ozone treatment utilized to remove the report that fruit jelly sulphur is hidden sulphite in the raw material.
Ozone (O
3) be oxygen (O
2) allotrope, form by three oxygen atoms, at normal temperature, under the normal pressure, can decompose and produce extremely strong antozone (O) and the hydroxyl (OH) of oxidability, can destroy bacterium rapidly, the internal structure of microorganisms such as virus, various pathogenic microorganisms there is extremely strong killing action, and have not can the residual harmful thing and cause the characteristics of secondary pollution, be considered to a kind of novel, desirable disinfectant, the ozone sterilization technology is as one of modern cold sterilization technology, demonstrated huge superiority, the security of using in food has obtained approval widely, but does not see have the ozone treatment utilized to remove the report that fruit jelly sulphur is hidden raw material sulphite content.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the method of content of sulfur dioxide in a kind of environmental protection, the safe and effective reduction fruit jelly raw material is provided, with ozone treatment is main means, select suitable treatment conditions according to the different material characteristic, can remove sulphite in the fruit jelly raw material to greatest extent, make the requirement that is up to state standards of product sulfur dioxide residual quantity.
