Title: Process for preserving products containing lactic proteins
Inventor: GRAF ERNST
IPC: A23C13/08
Filed: 1967-06-29
Abstract: Material containing lactic proteins, such as milk, cream and evaporated milk, is preserved by diminishing the heat-stabilizing effect of kappa-casein in at least a portion of the material and subjecting the resultant material to a heat treatment such as UHT or HTST sterilization or pasteurisation.  The inhibiting effect of the kappa-casein on the efficiency of the heating process may be reduced by rendering it insoluble by treatment with enzymatic agents such as rennet, by destabilizing it to heat by the addition of sodium pyrophosphate, or by the addition of denaturants for protein materials such as surfactants.  Other enzymatic agents specified are pepsin, neuraminidase, ficin, papain, pinguinain, extracts of Bernicasa cerfiera, Lynara carduncalus and Streblus asper and plants of the species Solanum, Calatropis, Withania and Lastiolla.  Other lactic protein containing materials specified are ice cream, dessert cream, and milk products for babies and dietetic purposes.  The effect of the agents used may be reinforced by the addition of calcium ions or by acidification, or may be moderated by an increase in pH or by the addition of phosphates or citrates.

Title: Improvements in or relating to the production of insulin crystals
Inventor: SCHLICHTKRULL JORGEN
IPC: A61K38/00
Filed: 1954-10-21
Abstract: In the crystallization of insulin from aqueous solution the size of the resulting crystals is controlled by adding a predetermined quantity of insulin seed crystals of a predetermined size. Spontaneous crystallization may be suppressed as far as possible or slight spontaneous crystallization may be allowed.ALSO:A process of crystallizing insulin from an aqueous medium of pH 5 to 7 in the presence of a crystallization-promoting metal e.g. zinc, cobalt, nickel, cadmium, copper, iron, or manganese, comprises seeding the medium with insulin crystals in an amount given by the equation <FORM:0766995/VI/1> where P is the weight in grams of seed crystals used, I is the weight in grams of insulin to be crystallized, and dp and di are the greatest size and the desired upper limit for size in micron of the seed crystals and crystallized insulin respectively. The size of the crystal is defined as the length in micron of the longest diagonal of the crystal.  Crystals of uniform size are obtained by preventing spontaneous crystallization e.g. by addition of a buffer substance the anion of which does not bind the crystallization-promoting metal at neutral reaction, and by the use of seed crystals of mainly the same size.  Suitable buffers are borate, diethylbarbiturate, maleate or acetate buffers. Crystallization may take place in the presence of halogen in ionic form e.g. as the halide of ammonia, alkali or alkaline earth metals, or mixtures thereof, in a concentration above 0.2 mole per litre, as in Specification 733,740 in which case phosphate or citrate buffers may be used.  A basic or acidic solution of insulin which may or may not contain the required content of metals, may be adjusted to the crystallization pH by means of a buffer; the insulin may be precipitated amorphously and subsequently changed into crystalline form by the addition of seed crystals together with the necessary metals, e.g. as an aqueous solution of the metal salt or by the addition of the seed crystals which may themselves exhibit sufficient metal content. The seed crystals may be formed by the process of Specification 766,994 and may be added in the form of an aqueous suspension or in dry freeze dried form.  An injectable insulin preparation may be prepared in conjunction with the process of Specification 709,927.

Patent GB-309865-A (GB)
Abstract: 309,865. Schering-Kahlbaum Akt.- Ges. April 16, 1928, [Convention date]. Addition to 254,753 and 274,439. Alkylphenols are prepared by the treatment of dioxydiphenyl-mono- or di-alkyl-methanes and their homologues with hydrogen diluted to a substantial extent (30-50 per cent by volume) with an inert gas or vapour, e.g. nitrogen or steam, in the presence of a hydrogenation catalyst. Higher temperatures may then be employed than in the process of the parent Specification, with consequent increase in reaction velocity, but without the occurrence of nuclear hydrogenation. The catalytic metals may be employed in the form of their precipitated carbonates and hydroxides, which then become converted into the active form in the autoclave and liberate sufficient steam to act as the diluent. Bismuth is excluded from the catalytic material. Examples are given of the production of p-isopropyl-phenol and phenol from di- (4-oxyphenyl)- dimethylmethane, and of thymol and m-cresol from di-(4- methyl-6-oxyphenyl)-dimethylmethane (see Specification 308,741), using pressures of 20-25 atmospheres and a temperature of 200‹ C. When the catalyst consists of a mixture of the carbonates or hydroxides of nickel, copper, cobalt and iron, the steam liberated functions as the inert diluent; otherwise, with previously-reduced nickel as the catalyst, nitrogen is present in the autoclave admixed with the hydrogen.
