The present invention relates to polypeptides capable of modifying the C8-atom of deoxynivalenol and methods (e.g., for detoxifying mycotoxins) based thereon. The present invention further relates to compositions, kits, transgenic plants, transgenic seeds, transgenic pollen grains, foodstuff, intermediate foodstuff; fodder, intermediate fodder; feed, intermediate feed; additive (e.g., foodstuff-, fodder- or feed additive), intermediate additive (e.g., foodstuff-, fodder- or feed intermediate additive); detoxifying agent, intermediate detoxifying agent; nutritional supplement, intermediate nutritional supplement, prebiotic, intermediate prebiotic and/or mixture/s thereof comprising one or more of the polypeptides capable of modifying the C8-atom of deoxynivalenol.

The present invention relates to a novel method for detoxification of trichothecene contaminated material. More specifically the present invention pertains to a method for biotransformation of a trichothecene by contacting material contaminated with trichothecenes with an exogenous non-animal glutathione-S-transferase (GST) having substrate specificity for the epoxide ring of the trichothecene. The invention further relates to recombinant GSTs and transgenic plants and animals expressing said GSTs.

The present application relates to a Gryllus bimaculatus extract and a method for preparing the same.

The present disclosure relates to the use of beta-glucosidase to enhance the production efficiency of desired steviol glycosides, such as rebaudioside M (reb M).

An oyster peptide with an effect of improving sexual function and a preparation method thereof are provided, the oyster peptide at least includes peptide segments RI, IR and VR in its composition. Based on a mass of the oyster peptide, a content of the RI is ≥3.60 mg/100 g, a content of the IR is ≥7.60 mg/100 g, and a content of the VR is ≥6.50 mg/100 g.

A method of reducing the asparagine content of whole grain flour for the production of baked goods includes treating whole grains by tempering the whole grains in an aqueous solution of an asparagine-reducing composition to concentrate and localize asparaginase activity in the bran and germ of the whole grains. In one approach, the asparagine-reducing composition may comprise an asparaginase enzyme. In another approach, the asparagine-reducing composition may comprise a yeast strain capable of degrading asparagine. The tempering treatment with the asparagine-reducing composition reduces asparagine in the whole grains by at least about 25%, resulting in a whole grain flour having an asparagine content of no more than about 250 ppm. Also described are baked goods having a reduced asparagine and acrylamide content comprising a whole grain flour obtained by treating whole grains with an asparagine-reducing composition during tempering.

The present invention features methods of extracting amylase trypsin inhibitors (ATIs) from processed and unprocessed foodstuff, determining bioactivity of ATIs, quantifying the amount of ATIs in a foodstuff, and reducing the content of ATIs in a foodstuff.

Provided in the present invention is a phospholipase C mutant with high enzyme activity, a polypeptide with the sequence as shown in SEQ ID NO:7, or a polypeptide derived from the phospholipase C formed by performing substitution, deletion or addition of one or a plurality of amino acids on the polypeptide of SEQ ID NO:7 while retaining the phospholipase C activity provided by SEQ ID NO:7. The phospholipase C mutant of the present invention can improve degumming efficiency and increase the yield of diacylglycerol (DAG) during degumming.

Adding (A) an amylomaltase derived from a bacterium of the genus Thermus to a starch-containing material, and further adding (B) a protein or lipid modification enzyme, or (C) a starch degradation product or (D) a starch degradation enzyme is useful for modifying a starch-containing food.

The present invention provides proline specific endopeptidases. The present invention further provides methods for use of proline specific endopeptidases for use in reduction of chill haze in a beverage, including beer. The present invention further provides methods for producing protein hydrolysates using proline specific endopeptidases. Also provided are methods of treating disease, including Celiac disease using proline specific endopeptidases. Also provided are nucleic acids encoding the proline specific endopeptidases and host cells for production of the proline specific endopeptidases.
