acids at elevated pressures and temps, below the b. p. The plant material and the acid arc placed into the cooker, then air is pumped in. By subsequent heating the pressure rises still further.
Highly gelling pectin. Mrwilcr Essigfabrik Mrsttten A.-G. Ger. 740,074, Aug. 20, 1943 (Cl. 53*. 1.02). A pectin-contg. material, e. g. apple residues, is treated with excess HjO for 2-10 min. at a pH 3 1 and a temp. 93-100. Without changing the HjO the temp, is lowered to 00-80, preferably 00-70, and thus kcjn ior 3-14 hrs.
Pudding starch from potato starch. Wirtschaftliche Vereinigung deutscher Strke-Industrien. Ger. 739,032,
Aug. 19, 1943 (Cl. 53*. 2.01). Potato starch with a
moisture content of 50% is treated at 55-57 and a pH of 5.5-0.6 until the product upon boiling with H,0 yields a
gelatinized, pudding-like mass. In Ger. 739,710, potato
1 starch is treated with alkalies until, upon the removal of the alkalies and neutralizing or acidifying the product or by oxidation, it yields a paste that is readily cut.
Fat rich in vitamin D from cacao shells. Heinrich Fincke (to Gebrder Stollwerk A.-G.). Ger. 739,053, Aug. 19, 194.3 (Cl. 30*. 2.20). Cacao beans or plant germs are added to the shells to bring the fat content up to 20-30%. The mixt, is finely ground, warmed slightly and pressed. * Feed from potato tops. Kurt Schwabe and Erich Leh mann (to Franz H. Rauch). Ger. 739,920, Aug. 19, 1943 (Cl. 53g. 4.01). Potato tops or the residue after cellulose extn. from potato tops are cleaned then mildly boiled for '/i~l hr. with 1-2% of an org. or inorg. acid. The cooking is at ordinary or raised pressure. The product is washed and dried.
