5. 1 sensory test
rainbow surface analysis
s54, D
Put the sample in a clean white porcelain dish, and evaluate it by normal sensory test in an odorless environment: 5.2 Determination of particle size of raw materials
Accurately weigh 1008 of the crushed raw materials, select a test sieve with a sieve size of 0.425 mm and 0.250 mm according to GB/T6003.1-1997, and follow the regulations of GB/T5917. 5.3 Determination of filtration uniformity
Follow the regulations of GR/T5918.
5.4 Determination of powder content
Follow the regulations of GB/T16765
5.5 Determination of water quality (loss rate)
5.5.1 Apparatus and equipment
a The sensory balance is 0.01 g:
b) Temperature packing oven,
NC/T 1066—2003
c) Frame made of metal mesh with a diameter of 0.0mm (height 6.=cm white light 6.5m, 7 strokes simplified form)) ruler with an accuracy of 0.1cm
stopwatch,
5. 5. Step 2: Weigh more than 100g of material (accurate to 0.1g) into the prepared sieve, place it in a hot water container with a depth of 1.2m, and slowly lift the sieve out of the water. Then put the material into the water and keep it away from the bottom of the sieve. Repeat this process three times. Take out the sieve, remove the water, and place the feed in the sieve in an oven at 1℃ to calculate the oxygen value. At the same time, weigh the same material without water, place it in a 10℃ oven to the desired weight, and then use formula (1) to calculate.
Dispersion rate, treatment:
The weight of the core of a pair of control materials, unit is gram (g); the weight of the post-treatment materials, unit is gram (

The scope of factory inspection is: food properties, powder content, moisture, protein and packaging, and appearance. 6.2.2 Type Inspection
Type inspection is carried out when the following conditions are met: a. When a new product is put into production:
The raw materials, formula and process have changed significantly, which may affect the product performance; during normal production, regular inspection is carried out after regular production! e. After long-term suspension of production:
When the inspection results are significantly different from the previous type inspection: when the quality control agency does not meet the requirements for type inspection. 5.3 Product Qualification Judgment
If the product is infested with insects, deteriorated, or has obvious odor and lumps, the product is judged as unqualified. If there are any unqualified items in the individual indicators, the original double sampling and re-inspection shall be carried out. Based on the inspection results, if there are still unqualified items, the product shall be determined as an unqualified product.
