摘要:
A method for preparing cut and frozen vegetables. The method according to the invention consists first of all in washing the vegetables in order to eliminate any residues of soil or other substances and materials that may have accumulated during picking. In a subsequent step, it is necessary to subject the vegetables to a mechanical treatment in order to isolate their edible part. One then proceeds by cutting the vegetables into granules with sizes comprised between 30 mm3 and 60 mm3 by using a cutting device, so as to define granules that can have a shape chosen preferably among those of a grain of couscous, a grain of rice, and the like. At this point one proceeds by immersing the granules in water for a predefined limited time. At a later time, one proceeds by scalding, with jets of hot water, said granules and air drying them. Both activities are performed with a water temperature comprised between 75°C and 85°C. Once the granules have dried, one proceeds by performing a manual sorting of the granules in order to identify any presence of defects therein. Finally, the granules are frozen by means of a freezer at a temperature comprised between -18°C and -30°C.

Methods of preserving fresh produce with a produce preservative which extends the shelf life of fresh produce, particularly cut fresh produce, and preserves the texture, flavor, appearance, crispness, and color of the fresh produce, particularly the exposed surface of the fresh produce, are provided. The method comprises: providing a solution of produce preservative comprising: water; a preservative cation which is selected from the group consisting of a strontium ion, lithium ion, barium ion, aluminum ion, copper ion, ammonium ion, iron ion, manganese ion, potassium ion, or mixtures thereof; and ascorbate ions, or erythorbate ions; wherein the ascorbate ions or erythorbate ions and the preservative cation are present in an ion ratio of preferably from 0.2:1 to 8:1, more preferably 0.75:1 to 8:1, even more preferably from 1:1 to 4:1, yet more preferably 1.5:1 to 3:1; most preferably 1.1:1 to 2.5:1; and, applying said produce preservative to the produce. The invention also relates to fresh produce preserved with the produce preservatives.

Se describe una nueva patata congelada, similar a la patata fresca, pero con menor contenido en almidón y que retiene menor cantidad de aceite al freirse que las patatas congeladas prefritas existentes en el mercado. Para ello las patatas se someten a un tratamiento en una solución salina, seguido posteriormente, o en la misma etapa anterior, de la adición de un conservante/oxidante alimentario, a los que opcionalmente pueden seguir etapas de secado con aire caliente, adición de un homogeneizador de color basificante y estabilizador de la estructura de la patata, enfriamiento en solución con adición opcional de colorantes y/o saborizantes alimentarios, según las diferentes variantes del procedimiento general consideradas y todo ello previamente a una etapa de secado mediante corriente de aire laminar, previo a su congelación. Este tipo de patatas se pueden utilizar en alimentación en general, siendo especialmente indicadas por su menor contenido calórico.
摘要:
The invention relates to a portion bag in which a portion of pre-deep-fried fries is packed and from which ready-to-heat fries can be obtained by means of post-baking without re-frying. The aim of the invention is to considerably reduce costs and preparation time. To this end, the fries have a fat content of 5-8 wt. % and a water content of 30-50 wt. %. The portion-bag preferably has a durability after the production that allows the bag to be stored at a typical ambient refrigerator temperature of 2-7 DEG C, especially at 4 DEG C, for a period of at least 40-60 days, or at room temperature, especially at 15-25 DEG C, for a period of at least 15-20 days without significantly compromising the quality of the fries obtained after baking.

The present invention describes an apparatus or system for extending shelf life of biological soft tissue, said apparatus comprising a holding means; means for introducing one or more cell protecting agents into the extracellular and intracellular space of the biological soft tissue; means for rinsing and means for extended cold storage intended for preservation. Moreover, the present invention also relates to a method for extending shelf life of biological soft tissue, said method comprising the steps of introducing one or more cell protecting agents into the extracellular and intracellular space of the biological soft tissue;and extended cold storing of the biological soft tissue intended for preservation of the same; and wherein the method also comprises rinsing the biological soft tissue before or after the introducing of one or more cell protecting agents into the extracellular and intracellular space of the biological soft tissue.
摘要:
The invention provides a method of preventing or reducing the growth of crystals in a substance which is susceptible to crystal growth in which colloidal particles having an amphiphilic structure, e.g. Janus particles, are contacted with the substance. Colloidal particles suitable for use in the invention include cross-linked, colloidal materials formed from hydrophobic monomers such as acrylates or methacrylates and hydrophilic monomers such as those derived from acrylic and/or methacrylic acid. The colloidal particles find particular use in methods of cryopreservation of biological samples (e.g. cells, tissues or organs), as a texture modifier in frozen food products, in the inhibition of gas hydrate formation, and as scale inhibitors.
摘要:
A food thawing article for evenly thawing frozen food in a microwave is disclosed. The food thawing article comprises an impermeable film backing, an absorbent layer adjacent the impermeable film backing, and a liquid permeable surface layer comprising a plurality of apertures covering the absorbent layer, opposite the impermeable film backing. A liquid is dispersed throughout the absorbent layer. The impermeable film backing is placed adjacent a frozen food item such that when the food thawing article is exposed to microwave energy, the liquid is heated and the heat is transferred to the food to thaw the food.
摘要:
The present invention is directed to frozen biocidal compositions. Specifically, the biocidal comositions comrise a frozen aqueous solution of a plurality of ions selected from the group consisting of halide and oxyhalide ions. The frozen biocidal compositions are useful in preserving or extending the shelf-life of perishable articles.
