We analyzed the components of the waste water in which the slices of apple were steeped to prevent from coloring, and the seeds of apple, as the by-products of apple-pulp manufacturing.1) The waste water is a light yellow liquid containing about 3% sugar in total, which will be suitable for the raw material of yeast production or other fermentations.2) The apple seeds contain about 20% fats, 10% carbohydrates, and 40% proteins.3) By the method of paper partition chromatography, we detected glucose, fructose, sucrose, raffinose and stachyose in the alcohol extract of apple seeds ; and glucose, galacturonic acid, arabinose and one more sugar probably supposed to be ribose in the water extract of seeds left for few days.As the free amino acids, we detected aspartic acid, glutamic acid, serine, asparagine, alanine, tyrosine, leucine or isoleucine, valine, threonine, . phenylalanine, tryptophan, arginine and histidine ; and in the hydrolysate of seed protein, aspartic acid, glutamic acid, serine, glycine ?, alanine, tyrosine, threonine, valine, proline, leucine or isoleucine, phenylalanine, arginine and histidine.
