冷冻鱼糜杂点数量的测定数据

冷冻鱼糜杂点的检测，需要从感官进行检测，确保其杂点能够与食品生产规定的标准要求相符合。杂点是评价鱼糜品质的重要指标，应严格按照相关标准进行检测，以确保产品的质量。1、样品采集，取出定量的冷冻鱼糜并解冻，在解冻的鱼糜上随机抽取5g左右的鱼糜并装入置入无色透明的薄膜袋，并标上编号；2、数据采集，将样品碾压成厚度小于1 mm的均匀平面，并通过肉眼观察杂点并计数，长度2mm以上的杂点数（大杂点）为P，1mm-2mm之间的杂点数（小杂点）为Q；3、数据处理，得到的杂点数通过公式M=P+Q/2得出杂点总数M的数据，M与标准值比对，判断产品是否合格；4、数据应用，为生产者提供冷冻鱼糜的质量品级，提供生产高质量鱼糜的方向，为消费者提供选择高质量鱼糜的依凭。

Detection of foreign impurities in frozen surimi: Sensory inspection is required to ensure that the foreign impurities comply with the standard requirements stipulated in food production regulations. As a critical indicator for evaluating surimi quality, foreign impurities should be inspected strictly in accordance with relevant standards to guarantee product quality.
1. Sample Collection: Take a quantified amount of frozen surimi and thaw it. Randomly extract approximately 5 g of the thawed surimi, place it into a colorless and transparent plastic film bag, and label it with a unique serial number.
2. Data Collection: Flatten the sample into a uniform flat sheet with a thickness of less than 1 mm, then visually inspect and count the foreign impurities. The number of impurities with a length of 2 mm or more (large impurities) is denoted as P, while the number of impurities between 1 mm and 2 mm (small impurities) is denoted as Q.
3. Data Processing: Calculate the total impurity count M using the formula M = P + Q/2. Compare the obtained M value against the preset standard threshold to determine whether the product is qualified.
4. Data Application: Provide producers with the quality grading of frozen surimi, offer guidance for producing high-quality surimi, and supply consumers with a reliable basis for selecting high-quality surimi.
