BULLETIN 77, HAWAII EXPERIMENT STATION 



Grapes, Isabella (skins and seeds removed) — The fruit was squeezed 

 from the skin and the seeds removed with irovy-tipped forceps. The 

 pulp was shredded with a silver fork. The samples used for the iron 

 analyses were ashed without drying. The remaining samples were taken 

 from materials which had been dried at a low temperature for several 

 days. 



Guavas, Common (whole) — Ripe firm guavas were carefully 

 selected. The stem and blossom end were removed and the remainder 

 chopped. The material for the iron determinations was not chopped 

 but consisted of representative slices cut from several guavas. 



Guavas, Common (seeds removed) — The material used for the deter- 

 minations was not a composite of a number of fruits. A lengthwise 

 section of a fruit was taken for each determination, the seeds carefully 

 removed and cleaned of all adhering flesh before they were discarded. 



Guavas, Common (juice) — The juice analyzed was that prepared 

 for the feeding of infants (p. 36). 



Guavas, Strawberry — The fruit was prepared in the same way as 

 the whole comon guavas. 



Litchis, Hei Y eh and Kwai Mi — The shell and the seed of the fruit 

 were discarded and, for all the determinations except iron, the flesh was 

 dried for several days at a low temperature. The samples used for the 

 iron determinations were ashed without drying. 



Mangos, Pirie and Victoria — The fruit was peeled, the seed removed 

 and the flesh sliced and chopped. 



Mountain Apples (36). 



Oranges, Hawaiian (with and without membrane) — The samples 

 used for analyses were unchopped sections of the oranges, with and 

 without the surrounding membrane. As it was impossible to chop or 

 mash the sections without losing comparatively large quantities of juice, 

 a composite sample was not prepared. Where more than one section 

 was used, they were taken from several different fruits. 



Oranges, Hawaiian (juice) — The oranges were cut in half. A large 

 glass orange squeezer of the household type was used to extract the 

 juice which was strained through a 10-mesh copper screen. 



Papayas — The fruit was cut in half and the seeds and membrane 

 removed with a silver spoon. The flesh was peeled and mashed with a 

 silver fork. 



Passion-fruit (juice) — The fruit was cut in half and the pulp and 

 seeds removed from the shell with a silver spoon. The juice was ex- 

 pressed by squeezing the pulp and seeds in four thicknesses of cheese- 

 cloth. 



Pineapples, Smooth Cayenne — The fruit was peeled and the flesh 

 surrounding the core was diced and used for analysis.
