【摘要】:采用TES-135色差儀對微生物發(fā)酵床大欄養(yǎng)豬場的160份墊料樣本進行色度分析,采用亨特(Hunter)色差公式:△E=[(△L)2+(△a)2+(△b)2]1/2對樣本間的色差進行統(tǒng)計分析,結合STDEV算法,根據樣本的色差相對于平均值(μ)的離散程度(σ),將墊料的發(fā)酵等級分為4級:0△E≤μ-2σ為發(fā)酵1級;μ-2σ△E≤μ為發(fā)酵2級;μ△E≤μ+2σ為發(fā)酵3級;△Eμ+2σ為發(fā)酵4級。通過表觀顏色、干濕度、味道、腐爛程度等對不同發(fā)酵等級的墊料樣本進行表觀描述,結果顯示墊料的色度分析能準確反應墊料的發(fā)酵等級。這為墊料發(fā)酵等級的快速鑒定奠定理論基礎。
[Abstract]:The colorimetric analysis of 160 padding samples from the pig farm of microbial fermenting bed was carried out by using TES-135 chromatic aberration instrument. The color difference formula of Hunter's Hunter was used to analyze the color difference between samples by using the formula E = [(Ln _ 2 (a ~ (2) (bn ~ (2)] _ (1 / 2), combined with the STDEV algorithm, the color difference between the samples was statistically analyzed. According to the dispersion of the color difference relative to the average value (渭) of the sample, the fermentation grade of the cushion was divided into 4 grades: 0: 0 E 鈮,
