OBJECTIVE To search the optimized recipe and preparation conditions of pH-sensitive liposomes.

The following optimum formula and processing parameters were obtained: 5% edible polysaccharide was used as the basic raw materials,supplemented with 2.

The optimum formula is obtained by the orthogonal experiment,and the content of the organic germanium in the rich germanium bread is assessed with ICP-AES method.

Through sensory evaluation the optimum formula of pumpkin puree is 0.

By orthogonal test,comprehensive physicochemical analysis and sensory evaluation,the optimal formula of this new beverage featured by light atrovirens colour,special flavour,moderate sweetness and sourness,mild mouth-feel and rich nutrients was determined as follows:30% nostoc,8% sugar,0.

With fermented milk's proportion determined as 35%,the processing technology for the beverage was described and the optimal formula introduced as fermented milk 35%,strawberry juice 20%,sugar 10%,compound stabilizer 0.

The optimum conditions of all the factors and the optimal formula of the drink were determined through the single-factor and orthogonal tests,respectively.

The best formula of yoghourt was determined through the orthogonal experiments.

this paper, the optimum formulation and the stability of lactobacillus chewing tablet using yogurt and freeze dried yogurt powder as raw materials respectively were studied.

In this article,by cross experimental design and extreme deviation analyzing mechod,the main factors of affecting the performances of heat proof materials have been determined and by analying these factors and indexes,the laws of the different factors of affecting the performances of materials and the optimum formulation for heat proof materials have been reported.

Differing from otherones now available at home and abroad,the solution needs only one allocation to achieve anoptimal scheme and it has no need of adjustment.
