The determination of test example 1, analogies and simulated conditions
Because service condition of the plastic products in vinasse and finished wine is entirely different, therefore, point vinasse and finished wine are examined
Consider analogies and simulated conditions.
1. the determination of vinasse analogies and simulated conditions
The plastic products used in fermentation process are mainly the slippers that the plastic cloth for taking cellar for storing things and roasting wine workman wear, most wine
The vinasse of factory are not directly contacted with plastic cloth, also have a small number of breweries directly to put up pit with plastic cloth.The slippers that roasting wine workman wears are several
It is that PVC material is done, plasticiser is easily advanced into vinasse, then is brought into wine.
A) determination of vinasse analogies
Liquor production is all solid state fermentation, and the vinasse wine degree of various odor types is about all 5%, and Laobaigan-flavour acidity is most
It is low, about 2%, Luzhou-flavor acidity highest, about 5%, that is to say, that vinasse acidity is between 2~5%.Acidity is higher, dissolution
Material it is more, therefore, we by Luzhou-flavor vinasse acidity setting analogies A, i.e. spirituosity 4~6%, acetic acid 4~6%
The aqueous solution；It is preferred that analogies A is spirituosity 5%, the aqueous solution of acetic acid 5%, 1 is shown in Table.
B) determination of vinasse simulated conditions
The fermentation time of odor type difference vinasse is different, and the vinasse fermentation time of Laobaigan-flavour is most short about 20 days, giving off a strong fragrance
Type fermentation time is most long about 70 days, and interior temperature in cellar is at 30 DEG C or so, with reference to GB/T 23296.1-2009《Food contact material
Material is tested and content assaying method and food to food and food simulants specific transfer in restricted substances plastics in plastics
The guide of analogies exposure condition selection》, set the 10 days migration test time of simulated conditions, 40 ± 1 DEG C of migration test temperature；
It is preferred that the 10 days migration test time of simulated conditions, 40 DEG C of migration test temperature, are shown in Table 2.
Table 1 is used for the analogies for migrating thing measure
Table 2 carries out time and the temperature conditionss of migration test using analogies
| The migration test time | 10 days |
| Migration test temperature | 40±1℃ |
2. the determination of wine analogies and simulated conditions
The plastic products contacted with finished wine mainly have bottle cap, bottle, envelope altar plastic cloth, wine conveying pipe road, storage container etc.,
It is most straightforward approach that plastic products are directly soaked with wine product, but fragrant liquor is more, and composition is sufficiently complex, wine degree from 25 to
70 degree, one is easy erroneous judgement, and two be the too many trouble of experiment, therefore needs design simulation thing, is used again according to the situation of simulation analyte detection
Finished wine makees last judgement.
A) determination of white wine analogies
It is low that the wine degree for the base liquor that each company produces has height to have, and Maotai-flavor liquor only has spends more 50, and delicate fragrance type wine can reach
Similar 80 degree, but delicate fragrance type vinic acid degree is low, and Maotai-flavor liquor acidity is high, takes into account various odor types, is considered with most exacting terms, if
Determine analogies B and C, be shown in Table 1.
B) determination of white wine simulated conditions
White wine is the food of long-term storage, and winter temperature is low, but summer temperature is high, and temperature is higher in transit sometimes, presses
Sighting target quasi- GB/T 23296.1-2009 10 days migration test times of setting, 40 ± 1 DEG C of migration test temperature is shown in Table 2.
Test example 2
1) confirmatory experiment that GC-MS is detected to volatile organic matter
GC-MS is the situation for fully understanding the volatile organic matter dissolved into leaching liquor using the purpose of full scan, will be treated
Test sample product sample introduction after analogies soak, while detecting immersion testing sample analogies, compares leaching liquor and analogies GC-
MS collection of illustrative plates, finds increased peak or peak area, computer spectrum storehouse (NIST11) retrieval is carried out to it, in conjunction with artificial spectrogram solution
Analysis, confirms its chemical constitution, suspicious compound need to further be confirmed, such as confirms chemical constitution with standard items, determines
Content etc..
The present inventor has prepared 10 representative standard substances to verify the reliability of qualitatively screening result,
Its detection limit under full scan pattern is determined with Agilent GC7890A-MS5975C.
