It is water-soluble to be comprised the following steps that with ABSORPTION INDEX measure:Sealwort dilated food sample was ground into 200 mesh After sieve, 1.6-2.0g of sample powder (W are taken0), it is put into centrifuge tube (w known to quality1) in, add 10mL distilled water, fully shake Swing, until powder is completely dispersed.30min is kept in 30 DEG C of water-baths, 30S is shaken every 10min, then turns in 4200r/min The lower centrifugation 15min of speed.Supernatant after centrifugation is poured into 500mL beakers (W2) in, it is dried to constant weight (W in 105 DEG C3).Centrifuge tube It is W to add precipitation quality4
Water-soluble sex index=(W3-W2)/W0× 100%;
ABSORPTION INDEX=(W4-W1)/W0× 100%.
2 testing results
Testing result is shown in Table 7 and Fig. 4.
Sealwort dilated food physical and chemical index measurement result prepared by the embodiment 14~22 of table 7
From table 7, according to GB17401-2014 regulation, dilated food moisture answers≤7%, and above product accords with Close Standard.Observation experiment number is it has been found that puffed strip moisture increases and uprised with water addition.Due to high by high temperature Pressure, the moisture of dilated food are not easy cooperating microorganisms than relatively low, i.e., can be appropriate only it is noted that not being secondary polluted Preserve.Understand that puffed strip moisture has a great influence to its subjective appreciation, and moisture is higher with reference to the data of table 6 and table 7, Mouthfeel is harder, more not crisp, and sample subjective appreciation score is lower, so water addition is higher, the moisture of puffed strip is got over Height, subjective appreciation score are lower.
As shown in table 7, the change of puffed degree has no evident regularity, and this is probably as caused by many-sided reason.First, may be used Can be that precision is inadequate because excessive using laboratory apparatus model;Secondly, hand stock, Wu Fajing may be taken due to experiment Charging rate is really controlled, charging at the uniform velocity, does not cause material expanded impacted;3rd, due to being that artificial naked eyes read data, exist Random error.Puffed degree is one of evaluation most representational index of dilated food, and puffed degree is bigger, and the fine and closely woven property of sample is got over Difference, air entrapment is bigger, and subjective appreciation score also can be impacted accordingly.
As shown in Table 7, in addition to indivedual bad points, overall puffed strip hardness increases and increased with water addition, it may be possible to due to Moisture addition is excessive, and raw material viscosity can be made to become big, so as to influence extrusion, cause puffed strip not crisp enough, hardness is bigger than normal. Hardness is that the important factor in order of subjective appreciation is done to puffed strip, and water addition is bigger, and puffed strip hardness is bigger, and puffed strip is more not Crisp, subjective appreciation score is lower.
As shown in table 7, understood with reference to Fig. 4, when water addition is 4 parts, water-soluble sex index highest, ABSORPTION INDEX is most It is low;When running water addition is 5 parts, water-soluble sex index is minimum, ABSORPTION INDEX highest, water addition and water-soluble sex index and Without evident regularity between ABSORPTION INDEX.But it is mainly there is opposite trend between water-soluble sex index and ABSORPTION INDEX Because insoluble diedairy fiber generates Partial digestion so that solable matter increasing number, so water-soluble sex index is aqueous It is higher on the contrary when measuring relatively low.Simultaneously as insoluble high polymer is broken, close institutional framework becomes when material is by Into loose unordered open structure, so that its retention ability declines, therefore ABSORPTION INDEX declines.
In summary, compared with other embodiment, the water content of sealwort dilated food prepared by embodiment 16 is minimum, expanded Relatively small, hardness minimum, water-soluble sex index highest are spent, and ABSORPTION INDEX is minimum.
