For example, some common names of sugar alcohols you may see on labels are sorbitol, mannitol, xylitol, isomalt, and hydrogenated starch hydrolysates.

Hydrogenated starch hydrolysates (HSHs) are mixtures of several sugar alcohols (a type of sugar substitute). Hydrogenated starch hydrolysates were developed by the Swedish company Lyckeby Starch in the 1960s. The HSH family of polyols is an approved food ingredient in Canada, Japan, and Australia. HSH sweeteners provide 40 to 90% sweetness relative to table sugar.

Hydrogenated starch hydrolysates are produced by the partial hydrolysis of starch – most often corn starch, but also potato starch or wheat starch. This creates dextrins (glucose and short glucose chains). The hydrolyzed starch (dextrin) then undergoes hydrogenation to convert the dextrins to sugar alcohols. Hydrogenated starch hydrolysates are similar to sorbitol: if the starch is completely hydrolyzed so that only single glucose molecules remain, then after hydrogenation the result is sorbitol.

Sporobolomyces species produce ballistoconidia that are bilaterally symmetrical, they have Coenzyme Q10 or Coenzyme Q10(H2) as their major ubiquinone, they lack xylose in whole-cell hydrolysates, and they cannot ferment sugars.

Proteins are made of a chain of dehydrated amino acids. When enzymes cut proteins into pieces they add water back to the site at which they cut, called enzymatic hydrolysis, for proteins it is called proteolysis. The initial products of this hydrolysis are polypeptides, and smaller products are called simply peptides; these are called wheat protein hydrolysates. These hydrolysates can create allergens out of wheat proteins that previously did not exist by the exposure of buried antigenic sites in the proteins.

The usage of raw starch is relatively small. Starch is mainly used as material both in the manufacture of food and non-food products. In food processing a lot of starch is converted to starch hydrolysates. Also it is used to receive puddings, jellies, desserts, caramel and other food products.

In 2009, Dr. Vercruysse from Ghent University in Belgium has proposed that insect protein can be used to generate hydrolysates, exerting both ACE inhibitory and antioxidant activity, which might be incorporated as a multifunctional ingredient into functional foods. Additionally, edible insects can provide a good source of unsaturated fats, thereby helping to reduce coronary disease.

Hydrolyzed proteins, or protein hydrolysates, are acid- or enzymatically treated proteins from certain foods. One example is yeast extract. Hydrolyzed protein contains free amino acids, such as glutamate, at levels of 5% to 20%. Hydrolyzed protein is used in the same manner as monosodium glutamate in many foods, such as canned vegetables, soups, and processed meats.

A diploid isolate of C. blankii had an observed "potential for use in single cell protein production from hemicellulose hydrolysates", which is related to Cellulosic ethanol (i.e., ethanol production). This yeast is one of several studied extensively for use in xylose fermentation. C. blankii has been tested as an aid for the degradation of hemicellulose hydrolycates.

Similar to xylitol, hydrogenated starch hydrolysates are not readily fermented by oral bacteria and are used to formulate sugarless products that do not promote dental caries. HSHs are also more slowly absorbed in the digestive tract, thus, have a reduced glycemic potential relative to glucose. However, they do have a laxative effect when consumed in large amounts.

About two hundred people contributed several thousand dollars for the painting of an oil portrait of McCollum by Paul Trebilcock in 1954. The work hangs in the lobby of the Alan Mason Chesney Medical Archives at Johns Hopkins. While working with Olaf S. Rask ten years before he retired, McCollum began to search for ways to separate specific amino acids from protein hydrolysates.

L-tyrosine and its derivatives (L-DOPA, melanin, phenylpropanoids, and others) are used in pharmaceuticals, dietary supplements, and food additives. Two methods were formerly used to manufacture L-tyrosine. The first involves the extraction of the desired amino acid from protein hydrolysates using a chemical approach. The second utilizes enzymatic synthesis from phenolics, pyruvate, and ammonia through the use of tyrosine phenol-lyase.

There are many uses of fish hydrolysate - from fish-based fertilizer, to its use as an animal food, or new human consumption applications which are developing. A number of scientific journals have cited the antiproliferative activity of fish protein hydrolysate, which makes it eligible for listing as a nutriceutical.Picot, L, et al., 'Antiproliferative activity of fish protein hydrolysates on human breast cancer cell lines', Process Biochemistry. Vol.

Because in HSHs the starch is not completely hydrolyzed, a mixture of sorbitol, maltitol, and longer chain hydrogenated saccharides (such as maltotriitol) is produced. When no single polyol is dominant in the mix, the generic name hydrogenated starch hydrolysates is used. However, if 50% or more of the polyols in the mixture are of one type, it can be labeled as "sorbitol syrup", or "maltitol syrup", etc.

Hydrogenated starch hydrolysates are used commercially in the same way as other common sugar alcohols. They are often used as both a sweetener and as a humectant (moisture-retaining ingredient). As a crystallization modifier, they can prevent syrups from forming crystals of sugar. It is used to add bulk, body, texture, and viscosity to mixtures, and can protect against damage from freezing and drying.

He was also appointed assistant to the Medical Unit of University College Hospital Medical School under Professor Harold Himsworth. The same year he married Margaret Coad. In April 1945 he was sent by the Medical Research Council to the recently liberated concentration camp at Belsen together with Janet Vaughan and Rosalind Pitt-Rivers, to study if starvation could be treated with protein hydrolysates (i.e. amino-acid mixtures).BergenBelsen.co.

Next, the whey must be filtered, and so is loaded into a massive web of ceramic filters and stainless steel turbines. These machines work to separate out the lactose as well as the fats, leaving a liquid of 90% whey protein. Hydrolysates are whey proteins that are predigested and partially hydrolyzed for the purpose of easier metabolizing, but their cost is generally higher. Highly hydrolysed whey may be less allergenic than other forms of whey.

The presence of eclosions, larvae and pupal third stages should not be counted because the damage has already occurred and the treatment would be worthless. The preventive treatments are carried out by spraying the olive grove with poisoned protein baits. The adults, being glycogenic, are attracted by nitrogenous substances necessary to supplement their low protein diet. The substances used as bait for the flies are protein hydrolysates and are poisoned with organophosphate insecticides (usually dimethoate).

Arthrobacter, like other bacterial genera including Brevibacterium, Microbacterium, and Corynebacterium are used for industrial production of L-glutamate. In industrial applications, Arthrobacter is often grown with low-cost sugar sources such as cane or beet molasses, starch hydrolysates from corn or cassava tubers, or tapioca. Along with sugar, ammonia and ammonium salts are added as a nitrogen source. The vitamins, minerals, and some other types of nutrients can be provided by adding corn steep liquour.

Lycasin is a trade name given by Roquette for hydrogenated glucose syrup (Hydrogenated starch hydrolysates). One of the major components of Lycasin is maltitol, derived from the hydrogenation of maltose. Depending on the dextrose equivalent (DE) of the syrup used in the hydrolysis, a variety of products can be made, with the name "lycasin" normally being reserved for lycasin 80/55 (80 referring to the dry content and 55 to the dextrose equivalent). The other grades (e.g.

The use of podiatry drills, in the absence of engineering controls and personal protective equipment, is an occupational hazard to the healthcare provider. Nail dust collected during foot care procedures performed in office settings has been found to contain keratin, keratin hydrolysates, microbial debris, and viable fungal elements, including dermatophytes (most commonly Trichophyton rubrum) and saprotrophs.Ward GW, Karlsson G, Rose G, Platts-Mills TAE (1989).

Archer J.P. Martin and Richard L.M. Synge worked together at the Wool Industries Research Association in Leeds. In 1941 they published a paper entitled ‘A New Form of Chromatogram Employing Two Liquid Phases’ in the Biochemical Journal. Martin and Synge described how they had used columns of silica with water, used as the stationary phase, whilst a second, non-miscible liquid, flowed down the column. The second liquid was the organic solvent chloroform, and they separated acetamino-acids from protein hydrolysates.

Enzymes may also be used to dissolve bones, scale and meat. If the larger chunks of bone and scales are screened out, calcium or mineral content may be lacking in the finished product form. If purchasing fish hydrolysate for agricultural applications, one should look at the label carefully for the concentration of mineral elements in the liquid. Some fish hydrolysates have been made into a dried product, increasing the potential for inclusion as an ingredient in other food or feed products.

Serum-based media may contain undefined animal-derived products such as serum (purified from blood), hydrolysates, growth factors, hormones, carrier proteins, and attachment factors. These undefined animal-derived products will contain complex contaminants, such as the lipid content of albumin. In contrast, chemically defined media require that all of the components must be identified and have their exact concentrations known. Therefore, a chemically defined medium must be entirely free of animal-derived components and cannot contain either fetal bovine serum, bovine serum or human serum.

The cells range in shape from egg-shaped, ellipsoidal, to elongated, measuring 2.5–5.0 by 5.0–15.0 µm, and occurring singly, doubly, or in groups of four. Asymmetrical blastoconidia are borne on short sterigmata, and measure 2.0–5.0 by 3.0–7.0 µm. The optimal growth temperature for the fungus occurs at a range of ; growth stops at . Like other Sporobolomyces species, S. koalae has coenzyme Q10 as its major ubiquinone, it lacks the monosaccharide xylose in whole-cell hydrolysates, and it cannot ferment sugars.

Caramel color is manufactured by heating carbohydrates, either alone or in the presence of acids, alkalis, and/or salts. Caramel color is produced from commercially available nutritive sweeteners consisting of fructose, dextrose (glucose), invert sugar, sucrose, malt syrup, molasses, starch hydrolysates, and fractions thereof. The acids that may be used are sulfuric, sulfurous, phosphoric, acetic, and citric acids; the alkalis are ammonium, sodium, potassium, and calcium hydroxides; and the salts are ammonium, sodium, and potassium carbonate, bicarbonate, phosphate (including mono- and dibasic), sulfate, and bisulfite. Antifoaming agents, such as polyglycerol esters of fatty acids, may be used as processing aids during manufacture.

An extensive genetic toolbox has been developed for S. stipitis that includes synthetic drug resistance markers for nourseothricin acetyltransferase gene (nat1), hygromycin (hph) and a synthetic form of Cre that enables excision of the markers. Engineered strains of S. stipitis will produce 57 g/l ethanol from pure xylose in under 48 h and adapted strains will produce significant amounts of ethanol from acid hydrolysates of lignocellulose. This natural ability of S. stipitis to ferment xylose to ethanol, has inspired efforts to engineer this trait into Saccharomyces cerevisiae. S. cerevisiae is preferred for ethanol production from grain and sugar cane, because it ferments hexose sugars very rapidly and is very robust.

Caramel coloring may be derived from a variety of source products that are themselves common allergens, namely starch hydrolysates (from wheat), malt syrup (in general derived from barley), or lactose (from milk). As such, persons with known sensitivities or allergies to food products are advised to avoid foods including generic caramel coloring or first determine the source for the caramel coloring before consuming the food. Caramel color produced from corn or cane-based materials would be unlikely to contain gluten due to the lack of gliadin in the carbohydrates. North American and European manufacturers mostly use glucose derived from corn or wheat to produce caramel color, which is highly processed and is generally considered gluten-free.

Beeman's Pepsin Gum Adams Pepsin Tutti Frutti Gum, marketed "For relief of indigestion and dyspepsia" Commercial pepsin is extracted from the glandular layer of hog stomachs. It is a component of rennet used to curdle milk during the manufacture of cheese. Pepsin is used for a variety of applications in food manufacturing: to modify and provide whipping qualities to soy protein and gelatin, to modify vegetable proteins for use in nondairy snack items, to make precooked cereals into instant hot cereals, and to prepare animal and vegetable protein hydrolysates for use in flavoring foods and beverages. It is used in the leather industry to remove hair and residual tissue from hides and in the recovery of silver from discarded photographic films by digesting the gelatin layer that holds the silver.
