A) weight-loss ratio
Result of the test:Weight-loss ratio situation of each test process bamboo shoots after storage in 30 days see the table below.
3 nanometers of fresh bamboo shoots incision protection agent of table are to the bamboo shoots influence for storing weight-loss ratio (%) in 30 days
In upper table, k1~k3 represents the basic, normal, high of proportioning content respectively, and specifically a certain kind is matched somebody with somebody respectively in protective agent
The average value of the result of the test of the basic, normal, high three proportionings contents level of square bar material, R is the extreme difference of three proportionings, reflects the formula
The size of material effect.For example, weight-loss ratio 7.0% corresponding to k1 tested numbers and A food-grade calcium hydroxides refers in table 3, in table 2
The average value for the weight-loss ratio that three groups of tested numbers (i.e. tested number 1-3) of the minimum proportioning content of food-grade calcium hydroxide are obtained.Table 3
Weight-loss ratio 5.4% refers to corresponding to middle k1 tested numbers and B food-grade calcium carbonates, the minimum proportioning content of food-grade calcium carbonate in table 2
The average value of weight-loss ratio that is obtained of three groups of tested numbers (i.e. tested number 1,4,7).
It is compared with a control by various protection agent prescriptions in 3 visible trial stretch of table, is respectively provided with significant reduce in storage
The effect of bamboo shoots weight-loss ratio.But the difference between each formula is little, and only calcium hydroxide content shows more regular change, with
Content increase, protectant compactness increase, obtains bamboo shoots water tariff collection slightly good.
B) otch color and luster
Each test group bamboo shoots situation of change of otch color and luster after storage in 30 days see the table below.
Influence of the 4 nanometers of fresh bamboo shoots incision protection agent of table to otch color and luster (Hunter ' L values) after bamboo shoots storage in 30 days.
In upper table, k1~k3 represents the basic, normal, high of proportioning content respectively, with table 3 similarly.
Hunter ' L values are to reflect object whiteness and the efficiency index of brightness.As seen from the above table, untreated bamboo shoots 0~
2 DEG C refrigeration 1 month after otch L values drop to less than 50, it is meant that whole brown stains.Compared with the control, agent prescription is respectively protected to preventing
Otch brown stain has significant effect, and wherein with the increase of content, prevent the effect of brown stain increases nano silicon, and rises
Effect it is maximum;The effect that other two kinds of components are risen with intermediate amounts is preferable.
C) the mildew and rot index of otch
Each test group bamboo shoots situation of change of the mildew and rot index of otch after 30 storages see the table below.
Influence of the 5 nanometers of fresh bamboo shoots incision protection agent of table to the mildew and rot index of otch after bamboo shoots storage in 30 days
Note:The statistical method of mildew and rot index:Mildew and rot degree is divided into 5 grades:0 grade --- otch is intact without mildew and rot;1
Level --- otch fraction is in xanthochromia, but is only limitted to surface;2 grades --- it is in xanthochromia that otch is most of, but is only limitted to surface;3
Level --- otch all changes colour, and its small portion blackening softens, and gos deep within 3 millimeters of tissue;4 grades --- otch major part blackening
Soften, go deep into tissue more than 3 millimeters.The quantity of bamboo shoots samples at different levels is counted, series is multiplied by, is all added, then divided by (5 × bamboo
Bamboo shoot sum).
From the test statistics result of table 5, control bamboo shoots overwhelming majority otch blackening is rotted, and blacking and rotten depth reach
2-3cm, remaining bamboo shoots otch are also changed into brown.Bamboo shoots after being handled using nanometer bamboo shoots incision protection agent provided by the present invention,
After 0~2 DEG C refrigerates 1 month, most of bamboo shoots otch maintains original color, and without the mark that rotted caused by microorganism growth
As only a small amount of bamboo shoots otch top layer slightly has browning, prevents that mildew and rot effect is fine.In various formulas, with nano silicon
Contribution it is maximum, be close to during highest dosage and entirely prevent going rotten, calcium carbonate is failed to understand as filler, the effect of doses change
Aobvious, host of the calcium hydroxide as regulation pH is best with the antiseptic effect of intermediate amounts.
Each index of summary, can draw the following conclusions:Nanometer fresh bamboo shoots in the range of formulation content of the present invention is cut
Mouthful protective agent be respectively provided with significant protection otch prevent brown stain and it is mildew and rot the effect of, wherein nano silicon is as anti-corrosive fresh-keeping
Main active, content effect at high-level (0.8 parts by weight) is preferable, calcium hydroxide as the host for adjusting pH,
It is best with the antiseptic effect of intermediate amounts (25 parts by weight).Calcium carbonate as filler, can larger content range (69.2~
79.8 parts by weight) in change, not impact effect.
Above-described embodiment is used for illustrating the present invention, rather than limits the invention, in the essence of the present invention
