Definitions

  • This invention concerns methods for the processing and modifying of natural waste, the so called " side streams " , from the foodstuffs industry so that the nutrients still present in the waste can be reused, so that this can make a contribution to pure, natural, clean-label foodstuffs that contribute to sustainability and to an improvement of the public health in various ways with the objective of binding water in foodstuffs.
  • the binding of water has the effect of making foodstuffs more tender and/or contain fewer ingredients and/or have an oil-reducing effect (after all, where there is water, there cannot be oil).
  • the current invention concerns the food ingredients and foodstuffs obtained by this method.
  • waste can include, for example, potato fibre, potato peels, sugar beet pulp, carrot fibre, apple remnants, citrus pulp, brewers' grains, coffee grounds, flour remnants, maize flour, bran, pea starch and misshapen, oddly shaped, discoloured, damaged or overripe vegetables or fruit and the like.
  • waste also means here waste streams, side streams, byproducts, waste products and the like. During the production of 'pure' ingredients, this currently amounts on average to about 25% of the amount of food resource being available as waste. A part of that waste stream will be converted to animal feed and then return as consumable food in the form of meat, milk and the like.
  • This 20% that will not be consumed contains, from the total amount of food raw materials, an estimated 16% of the macronutrients and 50% of the micronutrients.
  • These micronutrients include nutrients like high-quality proteins, complex carbohydrates, vitamins, minerals, nutritional fibre and other bio-active substances. This means that in particular the micronutrients are wasted, which impacts public health.
  • the Gezondheidsraad 'Dutch Health Advisory Board'
  • the 'purified' ingredients like crystal sugar, flour, oil and the like are, as macro nutrients, effective energy suppliers, but are poor in essential micronutrients like complex carbohydrates, high-value amino acids, vitamins, minerals, nutritional fibre and other bio-active substances. What is in crystal sugar, simple starch or oil except for the energy suppliers such as the macronutrients of carbohydrates and fats? Practically nothing! In Western food culture, food is relatively rich in macronutrients and relatively poor in micronutrients. An excessively high intake of macronutrients leads to obesity. A shortage of micronutrients and complex carbohydrates is in part at the root of many chronic conditions.
  • Ever-more foodstuffs are prepared in oil, by, for example, frying, baking, roasting, heating in the oven and the like, further referred to here for simplicity, both individually and collectively, as frying. During the preparation of those foodstuffs, they not only absorb oil, but trans-fats and acrylamide are created during the heating process. Trans-fats and acrylamide are carcinogens and mutagenic toxic substances for the human body. Objective
  • waste products are richer in micronutrients, including complex
  • This invention predicts that one or more waste substances, whether or not in combination with energy-rich and/or protein-rich resources and/or ingredients, can be mixed in a certain ratio and/or be pre-processed and/or be thermally treated, for example through extrusion technologies, or post-processed in a special way and/or be mixed before or during that processing with other waste substances so that an ingredient is created that can be added to foodstuffs and thereby provide extra functional value and/or extra taste and/or nutritional value and/or economic value to these foodstuffs by, among other things, binding extra water and/or as a result thereof reducing the absorption of oil during frying.
  • the pre-processing can consist of the reducing of the asparagine level and/or the reduction of the level of freely reducing sugars such as glucose.
  • the main processing can consist of a thermal treatment in which use is made of extrusion technology.
  • the obtained ingredient can be made smaller/ground in a specific way whereby the type of milling and the particle size to be obtained are important.
  • ingredients that bind and retail water and/or water-soluble substances such as proteins and, if needed, bond themselves and, if desired, reducing the level of oil and/or trans-fats and/or acrylamide, and, if possible, increasing the level of micronutrients.
  • This can be realized with one or more resources and/or ingredients.
  • the objective can be realized by using resources and/or waste substances that are derived from organically harvested resources or that are gluten-poor or gluten-free.
  • these foodstuffs By processing waste substances and using these in foodstuffs, these foodstuffs again become richer in complex carbohydrates, high-value amino acids, vitamins, minerals, dietary fibre and other bio-active substances. This makes the food healthier, and less waste of food takes place.
  • the ingredients that are produced in this way are pure, natural, clean-label, contribute to sustainability and to public health. Extra value can be obtained by making use of organically harvested resources and/or gluten- poor/-free resources.
  • Acrylamide presents a point of attention.
  • Acrylamide is a carcinogen and mutagenic toxic substance for which the permissible concentration in foodstuffs is increasingly lowered.
  • a level of acrylamide up to 3 times the permissible norm is created. With higher temperatures during the preparation of food, acrylamide can be created.
  • Acrylamide is quickly created via a chemical cascade reaction from the basic substances of asparagine and reducing sugars such as free glucose. This reaction proceeds more quickly as the temperature increases. As soon as the temperature during preparation reaches 170°C or higher, this chemical reaction is running more exponential. Organically harvested products such as potatoes contain a higher level of asparagine and glucose than the non-organically harvested varieties. With the help of the processes described hereafter, the level of acrylamide can actually be lowered by using a (bio-)coating so that an organic foodstuff comes under the permissible norm through the application of this coating.
  • pectins Certain raw materials or ingredients that are rich in pectins can bind water and water- soluble substances such as ethanol, amino acids, proteins and the like.
  • Pectins primarily occur in vegetables and fruit and in various bulb and tuber crops such as potatoes, in particular in products that are rich in water and feel hard, such as for example potatoes, carrots, (red) beets, (sugar) beets, apples, citrus fruits and the like.
  • Some plants that grow in water are also rich in pectins, such as seaweed, which is rich in glucomannan.
  • dietary fibre matrices In the cell wall of products that are relatively rich in pectins, there are dietary fibre matrices and, among other things, dietary fibre contains, for example, hemicellulose, cellulose and lignin. Because pectins bind water, they pull water into a still-living cell wall, whereby the cell wall swells and becomes, as it were, 'pumped up'. In order to limit the maximum size of the cell due to 'pumping up' of the cell wall, those cell walls contain cellulose and lignin in the dietary fibre matrices, threads that serve as 'armour' so that the cell becomes 'hard', and, as a result, the raw material, such as a potato, carrot, apple and the like feels hard.
  • the dried pectins As soon as the dried pectins, isolated from those cell walls, comes into contact with water, they immediately bind the free water and hold on to it. Depending on the kind of pectin, the water binding can range up to about 100 times the weight of the pectin. Substances that are soluble in water are bound along with the water.
  • Pectins also ensure that the oil uptake is reduced.
  • pectins prefer water and water-soluble substances, such as ethanol, amino acids and the like, and on the other hand, where there is water or water-soluble substances, food oil or food-oil- soluble substances cannot occur.
  • Pectins kick out food oil and food-oil-soluble substances, and pectins thereby have an oil-reducing effect if they simultaneously come into contact with water and/or water-soluble substances and with food oil.
  • the pectins have limited time to be able to bind water.
  • the process of water binding can be accelerated by increasing the surface size of products or ingredients that are relatively rich in pectins. That can be done by using extrusion technology.
  • the particles can be made smaller, so that the surface becomes relatively enlarged.
  • starch By thermally treating starch, it is gelatinized. As starch becomes more gelatinized, that starch has an increasing tendency to stick/cleave/bond. A good example is wallpaper adhesive. Gelatinized starch in a dry form takes up water as soon as the gelatinized starch comes into contact with water, and then a viscous mass forms. By using raw materials and/or ingredients that are rich in starch and by then mixing these with other raw materials and/or ingredients, an ingredient is created that bonds to a water- rich surface.
  • One of the possibilities for thermally treating such a product is the application of extrusion technology, by adding high pressure, increasing the temperature and adding water during the extrusion production process, the extrusion. The degree of gelatinization of the starch is determined by the pressure, the temperature, the amount of water and the length of time spent in the extruder.
  • ORFI samples Oil Reducing Food Ingredient.
  • ORFI samples are ingredients that in this case are composed of a mixture of about 10% potato side streams and about 90% flour remnants (all on the basis of about 90% dry stuffs). Then these mixtures are extruded, dried and milled into powder.
  • Figure 2 illustrates that the water uptake significantly improves
  • Figure 4 demonstrates that the oil uptake is significantly reduced in comparison with traditional crumbs that is made from bread crumbs or cracker crumbs.
  • the ORFI samples are a combination of the waste substances that are rich in pectins and of waste substances that are rich in starch. In this case, use is made of 10% potato side streams and 90% flour remnants, all based on about 90% dry matter. After mixing these substances, they were extruded, dried and milled.
  • ORFI adsorbs more moisture in comparison to bread and cracker crumbs has, among other things, to do with the fact that the pectin percentage in ORFI is higher than in bread and cracker crumbs.
  • the extrudate leaves the extruder via an opening in a matrix.
  • the extrudate is then cut by a cutter into pieces or slices or cut into 'blocks'.
  • These 'extrudate blocks' are then dried and/or roasted to a dry matter level of at least 88%.
  • the extrudate blocks are milled or broken/crushed with a specific mill with a specific sieve size. With different applications, different adsorption amounts can be obtained. These can be influenced as follows by:
  • a crushing mill increases the water uptake and reduces the oil uptake.
  • Sieve size in milling For the milling, the product to be milled is reduced in size until it can pass through a sieve of a certain size. The smaller the sieve size, for example smaller than 0.5 mm, the finer the powder. The more finely the extrudate is milled, the more the pore volume decreases, and the more the (oil) adsorption is limited. The more coarsely the extrudate is milled, for example with a sieve size of more than 0.5 mm, the less the pore volume decreases and the better the (water) adsorption is;
  • Vacuoles can arise in the extrudate. As soon as these vacuoles are broken open, the adsorption increases. By limiting the creation of vacuoles or by not breaking open the vacuoles, the adsorption will be limited;
  • roasting of the extrudate will decrease the adsorption.
  • method A In order to get to an ingredient that contributes to better water binding, it is important that during the process, the following method and set-up be applied - here called method A as an example:
  • Foodstuffs that consist of pieces or of ground meat of fish, such as mince, ground, sausage and the like need structure next to water-binding and bonding capacity.
  • Products that are relatively rich in hemicellulose, cellulose and/or lignin can give texture and structure, for example ingredients that come from the grain processing industry, such as wheat fibres, oat fibres and the like can give texture and structure.
  • a product like flour remnants, which is less high-value wheat flour, is relatively richer in the dietary fibres discussed here than high-value flour and can partly give texture and structure.
  • the temperature in the interior of the foodstuff in question does not exceed 100°C, because the water will be first evaporated.
  • the temperature on the inside can quickly rise, and the foodstuff in question must be removed as quickly as possible from the food oil in order to allow less opportunity for the formation of acrylamide in the foodstuff. If the temperature of the foodstuff in question thus does not exceed 100°C, then barely any acrylamide is created in the interior.
  • Acrylamide can initially be primarily created on the outside of the fried foodstuff.
  • the effect of a too-rapid rise in temperature on the inside of chips is that first the thinner parts, such as the tips, become brown and crispy, and that is caused precisely by the formation of acrylamide.
  • foodstuffs are also often pre-fried; that will be designated here as process Zl. After the pre-frying, the pre-fried foodstuff is then often frozen; that will be referred to here as process 12.
  • Raw materials, side stream and ingredients for the benefit of the production of foodstuffs that can contribute to better water-binding capacity and/or better bonding capacity.
  • Dietary fibre contributes not only to the nutritional value of foodstuffs, but often also delivers functional value.
  • the functional value can be the binding capacity of ingredients, whereby water is also considered as an ingredient, and the structure- and texture-giving capacity.
  • Pectins which are certain dietary fibres, bind moisture and hold onto moisture. Pectins naturally hold water and water-soluble substances such as proteins. As soon as ingredients that contain pectins are dried, these ingredients again bind moisture as soon as they come into contact with water or with water in which substances such as proteins are dissolved.
  • Hemicellulose, cellulose and lignin bind moisture to a lesser degree than pectins and primarily give texture and structure to a foodstuff.
  • Thermally treated starch not only contributes to the nutritional value of foodstuffs, but also delivers functional value. Dry starch does not do much, but as soon as thermally treated starch comes into contact with water or with substances that are dissolved in water, the bonding goes to the viscosity. The functionality of this bonding capacity can be increased as starch becomes increasingly accessibly for water, thus actually gelatinized.
  • Most raw materials, such as grains including maize and rice, tapioca root, potatoes and the like out of which starch is produced, such as wheat flour, rice flour, maize meal, tapioca, potato starch and the like are products rich in starch. In addition, there are the pea- and bean-type products, which are rich in both starch and protein.
  • the raw materials reported here in this list and/or parts thereof can be made smaller and/or dried and/or milled or otherwise processed. Examples are carrot pieces, beet slices or rejected parts that are still 'food grade'.
  • - Grains such as wheat, barley, oats, rye, maize and/or parts thereof;
  • Raw materials and/or parts thereof as reported in this list can be milled or otherwise processed, as with a thermal treatment.
  • the raw materials reported in this list can be made smaller and/or dried and/or milled. Examples are, among others, potato parts, rejected chip parts or cutting remnants or mush.
  • Proteins have a certain gelling action, and that can be of added value for some applications.
  • Ingredients are products that are isolated more or less as 'pure' out of the original food raw materials and/or parts thereof. Some examples of this are potato starch that is isolated from the industrial potato or flour that is isolated from wheat.
  • - Flour such as wheat flour, maize meal, rice flour, potato starch, tapioca.
  • Ingredients can be utilized in both wet and dry forms.
  • potato parts such as chips, potato crisps, potato parts and the like
  • Potato scrapings and potato pieces that become available as remnants during the production of potato parts, such as chips, potato crisps, potato parts and the like
  • Fruit waste actually the remnants that become available during the production of fruit and that has been cleaned of the hard parts such as pits, stems, seeds and the like.
  • Examples of fruit waste are peels, cores and the like;
  • both the wet and the dry/dried form applies.
  • potatoes are often peeled.
  • the potato peel forms about 10% of the weight of the potato.
  • the peeling of the potato can be done by scraping, peeling or removing the potato peel with the help of steam techniques. In the latter case, steam is taken up by the potato peel, so that they dry stuffs level of the potato peel falls from about 25% to about 12.5% or even lower.
  • the remnants that are rich in hemicellulose, cellulose and lignin primarily give texture and structure to foodstuffs in the production thereof.
  • - Bran actually the remnants during the production of flour from grain.
  • Examples are wheat bran, oat bran, rye bran, barley bran, rice bran, maize bran and the like.
  • Flour remnants actually the remnants that become available during the production of wheat flour;
  • Various raw materials and ingredients from lists I through VII can be pre-processed and then individually or in mixed form be added to foodstuffs or be extruded (extruded, dried and milled) before the addition.
  • the milled extrudate can be individually added to foodstuffs or mixed with raw materials or ingredients from lists I through VII and then added to foodstuffs.
  • the objective is to improve the (water) binding of ingredients in foodstuffs and/or to improve the bonding to foodstuffs and/or to reduce the oil uptake during frying and/or to reduce the acrylamide level and/or to entirely or partially gelatinize the starch and/or to entirely or partially simplify the starch.
  • the process can consist of various steps, of which, if needed, one or more steps can be skipped.
  • process A By first cleaning potatoes or other raw materials, such as carrots, beets and the like that will be peeled or vegetables that will be cut, extra-well of contaminations such as sand, clay, stems, leaf parts, waste plastic, metal, rotted parts and the like, the peels or cutting remnants contain fewer contaminants. This will hereafter be designated as process A. With the cleaning of potatoes or other raw materials of their peel, peels are created, whether or not enriched with water. With the cutting of potatoes, vegetables and fruit, whether or not enriched with water, cutting remnants are created. This will hereafter be designated as process B. By pulping the peels and/or the cutting remnants so that the cell walls are affected, the cell contents can become freely available. This process will hereafter be designated as process C.
  • Asparaginase can be added to the resulting mousse, so that the asparagine is broken down, or at least is no longer available for the formation of acrylamide.
  • This fermentation process will be hereafter called process D.
  • free reduced sugars can largely be removed from a raw material or raw materials and/or from an ingredient or ingredients, such as from peels or cutting remnants by finely pulping these and then centrifuging off the watery effluent in which the reduced sugars are dissolved. The precipitate then contains barely any free reduced sugars, so that the chance of the creation of acrylamide is also reduced.
  • process El A second option is to ferment one or more raw materials with enzymes so that the starch is entirely or partially simplified, so that a sweeter end product is obtained. This process will be designated as process E2.
  • centrifuging can be done in multiple steps with an increasing size of the sieve in each step.
  • a centrifuge can be done with (centri-)sieves with a sieve size of 40 ⁇ , process Ex-40 (fraction equal to or smaller than 40 ⁇ ), then with 70 ⁇ , process Ex-70 (fraction equal to or smaller than 70 ⁇ and with the application of Ex-40 larger than 40 ⁇ ) and then with ⁇ , process E-100 (fraction equal to or smaller than ⁇ and with application of process Ex-70 larger than 70 ⁇ ); the remaining fraction is then larger than ⁇ .

Abstract

La présente invention concerne des procédés permettant de traiter et de modifier des déchets naturels, dits "courants intermédiaires", générés par l'industrie alimentaire de sorte que les éléments nutritifs encore présents dans les déchets puissent être réutilisés, ce qui contribue à fabriquer des produits alimentaires purs, naturels et propres, et contribue aux efforts de durabilité et d'amélioration de la santé publique de différentes manières avec pour objectif de lier l'eau dans les produits alimentaires. La liaison de l'eau a pour effet de rendre des produits alimentaires plus tendres et/ou de renfermer moins d'ingrédients et/ou de réduire leur teneur en lipides (la présence d'eau chasse la présence d'huile). L'invention concerne également les ingrédients alimentaires et les produits alimentaires obtenus par ce procédé.
