Abstract: A method of preparing iron-fortified beverage, wherein either aqueous solution of lactoferrin, iron and sodium bicarbonate or aqueous solution of iron lactoferrin is adjusted to the ionic strength to satisfy the conditions given by the formulae below and sterilized by heat; solution of the ingredients other than the above is also sterilized by heat; and the two are mixed to obtain the product: and a method of processing iron-fortified beverage, wherein all ingredients including lactoferrin are dissolved in water and, if the ionic strength of the solution is adjustable to the conditions given by the following formulae, adjusted to the ionic strength given, and sterilized by heat to obtain the product.log I.ltoreq.-T/66.7-0.1(wherein 60.ltoreq.T.ltoreq.80)log 1.ltoreq.-1.3(T.gtoreq.80)(T indicates temperature of sterilization in degrees Celsius.

Abstract: A flame-retardant polyamide resin composition having an excellent flame-retarding property clearing over the level V-0 of the UL-94 Standard contains a flame retarder consisting essentially of:(1) a first flame-retarder component consisting essentially of at least one melamine derivative of the formula (I) ##STR1## wherein R.sup.1 and R.sup.2 represent, independently from each other, a divalent hydrocarbon radical having 1 to 15 carbon atoms and n represents zero or an integer of 1 to 5, and(2) a second flame-retarder component consisting essentially of at least one member selected from unsubstituted and substituted melamine cyanurate compounds and unsubstituted and substituted organic carboxylic acids and anhydrides having a boiling point and/or a decomposition point higher than the melting point of the polyamide resin matrix.
