Abstract: Hydrolysis of plant kingdom polysaccharides by treatment with SPS-ase preparations.SPS-ase is an enzyme adapted to hydrolyzing the water-soluble protein binding polysaccharide present in soy flour decomposed by use of conventional pectinases, which polysaccharide is believed to be widespread in plant kingdom substances. Treatment with an SPS-ase preparation can clarify juices, wines and beers, hydrolyze process wastes such as sugar beet pulp, pomace, and soy milk remanence, improve the digestability of silage, and reduce the viscosity of wort.

Abstract: A harshness reducing, enzymatic additive for a main wash detergent based on a fungal cellulase, i.e., a cellulase produced by means of Humicola insolens. The enzymatic additive can be produced in high yields and has an extraordinarily high activity at alkaline pH values, whereby it is possible to mix the additive with a main wash detergent and perform the harshness reduction and the washing as a single operation.

Abstract: Method of producing an egg white substitute material from soy protein. The method comprises extraction of a defatted soy bean material at a pH between about 6.0 and 10.5, separation, subjection of the supernatant to one or more ultrafiltrations and proteolytic hydrolysis of the supernatant or some fraction thereof to a DH between 1 and 8. The hydrolyzed soy material exhibits both a superior whipping or emulsifying ability and a good nutritional value, and it has no bitter taste.

Abstract: A novel, purified peptide having the following amino acid sequence:Arg-Ser-Leu-Gln-Asn-Thr-Glu-Glu-Lys-Ser-Arg-Ser-Phe-Pro-Ala-Pro-Gln-Thr-Asp -Pro-Leu-Asp-Asp-Pro-Asp-Gln-Met-Thr-Glu-Asp.The peptide may be used as medicament, e.g., in the treatment of gastroduodenal ulcers.

Abstract: Bacillus serine proteases are acylated with an acyl radical of a monocarboxylic or dicarboxylic acid of about 1 to 6 carbon atoms to thermally destabilize the proteases at least about 3.degree. C. The acylated proteases have at least about 50% of their activity before acylation, and are advantageous in processes where it is desired to inactivate the proteases at a certain point in the process.

Abstract: Deacidifying wine by passage through an alginate gel containing living cells of Leuconostoc oenos therein. To ensure maximum viability, the alginate gel is stored in a resting medium, preferably sterile grape juice containing 5-12% ethanol. Before deacidifying wine the immobilized cells are conditioned to a wine milieu.

Abstract: The disintegration process for prune juice production is improved through cooking prunes until substantial disintegration has taken place followed by treatment with cellulase, e.g., the cellulase of Trichoderma reesei, and optionally with a pectinase, which allows for good yield recovery of prune juice through centrifugal separation.

Abstract: The invention relates to a novel purified polypeptide which is recoverable from porcine pancreas glands. The amino acid composition of the said polypeptide has been determined to be as follows:Trp (2), Lys (4), His (1), Arg (5), Asx (10), Thr (3), Ser (9), Glx (12), Pro (12), Gly (6), Ala (6), Cys 1/2 (14), Val (7), Met (2), Ile (3), Leu (1), Try (2), Phe (7), wherein the determinations are subjected to the usual error of .+-.10 percent of the indicated figures. The partial amino acid sequence comprising a total of 45 amino acids from the N-terminal, is believed to be: ##STR1## wherein pyrGlu (residue 1) stands for pyroglutamic acid. The purified polypeptide is of utility as a medicament, for example as a spasmolytic agent, as an agent for treatment of gastroduodenal ulcers and as a diagnostic aid.

Abstract: Microbial rennet such as from Mucor miehei is thermally destabilized by treatment of the rennet in an aqueous medium with oxidizing agents containing active chlorine such as hypochlorites. The thermally destabilized rennet is advantageous for cheese making where absence of rennet activity in pasteurized whey is desired.

Abstract: A process for converting insulin compounds containing the human insulin moiety ##STR1## into h-In-Thr.sup.B30 esters through transpeptidation of such insulin compounds with a threonine ester in solution of water and a water miscible solvent in the presence of trypsin and optionally an acid.Yields in excess of 60% are obtained by limiting water content to less than 50% v/v of the reaction mixture and controlling reaction temperature, with below ambient temperature and extended reaction times being preferred.A preferred starting material is the crude porcine insulin recovered from insulin salt cake and contaminated by proinsulin and degradation products thereof which contaminants convert into the h-In-Thr.sup.B30 ester.

Abstract: A method for producing soy protein hydrolysate involving water washing fat-containing soy material at a pH of 3.5-5.5 thereby partially defatting the soy material; then hydrolyzing the partially defatted soy material with a proteolytic enzyme in the presence of water and a base to a DH in the range of 1-20; and recovering the aqueous soy protein hydrolysate from soy derived oil and solids in the hydrolysis mixture. The oil is recovered from the wash water and from the hydrolysate mixture.
