Ultrasonic milk analyzerAPPENDIX 5: EASY CALIBRATION OF THE MILK ANALYSERBY CALCULATING THE BASIC PARAMETERS VIA FORMULASDETERMINATION OF THE BASIC PARAMETERS IN THE MILK SAMPLEBY USING FORMULAS IS NOT AS PRECISE AS USING THE ARBITRARYMETHODS, BUT IS SUITABLE FOR USAGE IN FIELD WORK.5.1. Determination some of the parameters by formulasThere is dependence between the different parameters in milk and itsdensity, which may be expressed with mathematical equation. On this basedifferent formula, tested and confirmed by the classical laboratory methodsfor analyses, are developed. We recommend the following:5.2. SNF determination.For determination of SNF the correlation dependence exists between themilk’s density, fat and SNF in the milk. When the density and the fat areknown, the SNF can be calculated.There are several formulas with different applicability.А/ When the salts and fat are knownSNF is calculated by subtracting the fat percentage from the salts.SNF = Salts – F (%)WhereSalts – salts in (%),F – fat content in (%),This formula is used for determination of SNF in whey, buttermilk, and cream.B/ Known quantity of fat and density (most commonly used method whenmaximum accuracy is needed).We recommend the following formula:0,075∗F%+ 100−100/densitySNF =0,378This is a universal formula and actual for milk of almost all kind of cows andsheep all over the world.Operation manual 72/98
Ultrasonic milk analyzer5.3. Determination of lactose contentWe recommend the following formulas:А/ for cow milkLact. = SNF * 0,55 (% )WhereSNF – content of SNF in percentages (%),0,55 – constant coefficient.B/ for sheep milkLact. = SNF* 0,45 (% )WhereSNF –solids-non-fat content in percentages (%),0,45 – constant coefficient.This is an actual coefficient for sheep breeds on the territory of the BalkanPeninsula.5.4. Determination of salts contentWe recommend using the following formulas:А/ for cow milkSalts = SNF* 0,083 (% )WhereSNF – solids-non-fat content in percentages (%),0,083 – constant coefficient.B/ for sheep milkSalts = SNF * 0,075 (% )WhereSNF – solids-non-fat content n percentages (%),0,075 – constant coefficient.Operation manual 73/98
