Disclosed is a method for constructing fluorescent Bombyx Mori silkworm silk irradiated by near-infrared light and its products, comprising: (1) preparing upconversion nanoparticles, and performing surface modification with concanavalin to obtain modified upconversion nanoparticles; (2) uniformly dispersing the modified upconversion nanoparticles in water to formulate an aqueous solution of the upconversion nanoparticles, (3) picking mature mulberry leaves, immersing the mulberry leaves in the aqueous solution system of the nanoparticles, leaching water, and naturally drying the mulberry leaves; (4) after silkworms have grown for a set time, feeding the treated mulberry leaves to the silkworms until the silkworms spin silk cocoons; and (5) collecting the silk, so as to obtain mulberry silk that fluoresces under near-infrared light. The present invention selects upconversion nanoparticles capable of emitting fluorescence under the irradiation of near-infrared light which has stronger penetration, thus has better application in deep tissue imaging.

A hydrolysis method for obtaining a hydrolysed dry food product in powder form by adding an acid solution to a material having a vegetable or animal origin for obtaining an acidified paste having a pH of less than 2.0; leaving the acidified paste to rest for the hydrolysis to take place; adding to the acidified paste obtained in the previous step a ground flour having a vegetable or animal origin having a granulometry such that, at least, 50% thereof has a size of less than 1 mm; adding an adsorbent excipient to the mix of acidified paste and ground vegetable/animal flour obtained in the previous step; and leaving the mix of acidified paste, ground vegetal/animal flour and adsorbent excipient to rest until the hydrolyzed dry food product in powder form is obtained.

A process of preparing a sterilized wet pet food product is provided, as well as a sterilized wet pet food product provided by the process. Use of the wet pet food product to feed a companion animal is also contemplated.

A computer-implemented method for predicting a feedstuff and/or feedstuff raw material is described. The method comprises providing a near infrared (NIR) spectrum of a sample of an unknown feedstuff raw material and/or feedstuff. The absorption intensities of wavelengths or wavenumbers in the spectrum are transformed to give a query vector. A set of database vectors of a population of spectra of known feedstuff raw materials and/or feedstuffs is also provided, and these comprise at least 50 spectra of samples of each feedstuff and/or feedstuff raw material from each of its global growing areas. The similarity between the query vector and each of database vectors is analyzed to produce a score, and the feedstuff raw material and/or feedstuff of the database vector with the highest score is assigned to the sample.
