  • Publication number: 20190216112
    Abstract: The invention relates to a deacidified juice, as well as a process for deacidifying a cranberry juice to be deacidified that is eluted on a bed or a weak anion exchange resin at a rate (BV/h) such that the deacidified cranberry juice leaving the elution has a pH=pKa1 (malic acid)<pH<pKa (benzoic acid). The invention also relates to a food composition that comprises this deacidified fruit juice.

  • Patent number: 4920645
    Abstract: A household utensil, in particular a fruit or vegetable peeler is composed of a handle, a cutting blade and two support bars parallel to the blade. The blade and at least one of the support bars form a unit which moves in translation towards the handle and can be retracted into the handle. The retraction of the mobile unit into the handle releases the peels wedged between the blade and the support bars. The present invention is particularly useful for peeling asparagus.

  • Patent number: 4353751
    Abstract: A method of producing mineral fillers containing hydrated calcium monocarboaluminate.Al(OH).sub.3, CaCO.sub.3 and Ca(OH).sub.2 are reacted together in the presence of water, the operating temperature range being of 50.degree. C.-100.degree. C. Although these materials are insoluble, a quick reaction occurs as well in a highly concentrated solid medium as in a diluted medium. According to a preferred embodiment, the amount of water is such to obtain a final dry matter content of 50%, and the substantially solid resulting paste is directly brought to the fluidity required for use by means of a defloculating agent.Application to paper coating.

  • Patent number: 4081286
    Abstract: A hydrated mineral charge is manufactured by grinding a composition selected from the group consisting of calcium aluminates, aluminous cements, and Portland cements, to a powder having an average fineness of from about 3,000 to about 5,000 square centimeters per gram (Blaine's specific surface), hydrating the composition with water to form a paste at a temperature from about 10.degree. C to about 100.degree. C, and adding a sufficient quantity of a liquefying surface active agent to the paste so that its viscosity is less than about 5,000 cps, and so that the paste has a solid content from about 60 percent to about 80 percent by weight.

  • Patent number: 4081287
    Abstract: A process includes hydrating between about 10.degree. and 100.degree. C, one of the synthesized anhydrous calcium aluminates prepared specially or stemming from the manufacture of hydraulic binders or of anhydrous calcium silicates, groundup to an average degree of fineness, with a quantity of water of such an order of magnitude that a paste is formed, having dry extracts between about 5 and 70% by weight; subjecting at least the large particles to a vigorous agitation during the hydration to form a suspension, drying the formed suspension to a dry powder and collecting the obtained dry powder.

  • Patent number: 4002484
    Abstract: A substantially stoichiometric mixture of calcic aluminate and calcium sulphate, as white as possible, formed at a temperature in the range of about 20.degree. to 90.degree. C, is hydrated simultaneously; water is added at least in stoichiometric proportions for the reaction and at a maximum in an amount such that after the reaction a product is obtained containing 5% (dry) ettringite and 95% (by weight) water, stoichiometry being defined, for example by the reactionCaO,Al.sub.2 O.sub.3 + (CaO, H.sub.2 O) + 3(CaSO.sub.4, 2H.sub.2 O) + 24 H.sub.2 O.fwdarw.(CaO).sub.3, Al.sub.2 O.sub.3, 3 CaSO.sub.4, 32 H.sub.2 O (ettringite)It is thus possible to obtain in an economical and very flexible manner, ettringite, or suspensions containing same, for all industrial uses, notably for paper-making.

  • Patent number: 3998651
    Abstract: A compound of calcium carbonate and of hydrated tobermorites, constituted of 70 to 15% tobermorites, which may contain free hydrated silica in amounts to 0 to 15% in weight expressed in SiO.sub.2, and of 30 to 85% calcium carbonate. The process includes completely hydrating white Portland cements between about 5 and 100.degree. C to form a paste having a dry extract of 5 to 70% by weight until at least a decrease in the pH-value occurs.The compound is an industrial charge particularly for paper-making and paint-making industries.
