With Anli as the test material,this paper mainly studies the optimization technology of Anli cream and the impact of different physicochemical treatment methods on the quality characteristics of Anli slag powder.This paper aims to provide theoretical basis for the full utilization of Anli resources.The main results are detailed as follows:1.Optimization technology of Anli cream The basic formula of Anli cream is added with the total sugar content of 10%,and the quality ratio of white granulated sugar and high fructose corn syrup is 7:3.Under this condition with comprehensive score as the optimization index,it is shown by the test results that the optimization process parameters of Anli cream are as follows:sodium erythorbate content of 0.28%;pectinase content of 0.28%;pectinase hydrolyzing temperature of 57?;pectinase hydrolyzing duration of 145 min;vacuum concentration temperature of 71?;vacuum concentration duration of 39 min;brightness of Anli cream up to 52.50;light transmittance up to 99.0%;content of soluble solids up to 82.5%;and the comprehensive score up to 104.90.2.Impact of different physicochemical treatment methods on the quality characteristics of Anli slag powder?1?For Anli slag powder treated in different drying manners,the adsorption property is ranked in the large-to-small order of vacuum freeze-drying>oven drying>natural drying;the cation exchange capacity is ranked in the large-to-small order of oven drying>vacuum freeze-drying>natural drying;the oxidation resistance is ranked in the large-to-small order of vacuum freeze-drying>natural drying>oven drying.It can be seen from the analysis of electron scanning microscopy that both the samples treated through vacuum freeze-drying and the samples treated through oven drying show a porous structure,while the samples treated through natural drying have the porous structures reduced significantly.?2?For Anli slag powder in different grinding particle sizes,the adsorption ability,cation exchange capacity and oxidation resistance strengthen gradually with the decrease in particle size.It is concluded from the analysis of electron scanning microscopy that within the scope of a certain particle size,the porous structure of Anli slag powder does not disappear at all in case of grinding,while the porous structure disappears in case of superfine grinding,which indicates that superfine grinding not only destroys the fiber matrix,but also increases the specific surface area.?3?For Anli slag powder treated in different decoloring manners,the adsorption property is ranked in the large-to-small order of Na2SO3 decoloring samples>H2O2 decoloring samples>non-decoloring samples;the cation exchange capacity is ranked in the large-to-small order of H2O2 decoloring samples>Na2SO3 decoloring samples>non-decoloring samples;the oxidation resistance is ranked in the large-to-small order of non-decoloring samples>Na2SO3 decoloring samples>H2O2 decoloring samples.It can be seen from the analysis of electron scanning microscopy that non-decoloring samples display an irregular porous structure,Na2SO3 decoloring samples display a porous structure with perforated holes,and H2O2 decoloring samples display a relatively uniform porous structure like a honeycomb in shape.?4?For Anli slag powder treated in different physicochemical manners,it can be concluded from the analysis of infrared spectrum scanning that such physicochemical treatment including drying,crushing and decoloring neither changes the fiber composition,nor destroys the structure of Anli slag powder.
