Definitions
- the present invention is part of the development of an extract of natural flavors, specifically UMAMI flavor based on mushrooms.
- the UMAMI flavor has recently been identified as such, and it has been defined as the fifth flavor, that is, people could recognize between 5 different types of flavors: sweet, salty, bitter, acid and UMAMI.
- the word UMAMI is a Japanese term meaning savory, and is described by its pleasant salty or meaty flavors naturally present in many plant and animal foods. Physiologically we know that UMAMI has effects on the tongue: it stimulates salivation and generates a physiological sensation associated with pleasant stimuli. Chemically we know that the Umami flavor is due to the specific receptors of the molecules responsible for the UMAMI flavor on the tongue, among which glutamate, aspartate and 5' nucleotides have been identified.
- the UMAMI flavor has great applications in the food industry since. It is a flavor enhancer, as we indicated, it makes food “tasty”, but advantageously it does not contain sodium, so it constitutes a healthy replacement for salt, which has such a negative impact on people's health. Similar to salt, UMAMI enhances the flavors of food, so the variety of uses is very wide.
- UMAMI flavor has been obtained from different sources, such as various vegetables including tomato, onion, mushrooms and seaweed.
- the invention points to a new method for obtaining UMAMI from mushrooms, which stands out for its speed and product quality.
- the process of the invention allows obtaining a concentrated product, without contaminating flavors of the source material, which gives greater versatility. to the composition obtained.
- Zhao Zao, Yonggan, et al. "Progresses on processing methods of umami substances: A review.” Trends in Food
- the subject of the invention is found within the enzymatic hydrolysis processes to obtain UMAMI, which differs from what is known in the prior art, in improving both the effectiveness and efficiency of the process.
- the inventors have developed a rapid method to obtain UMAMI of excellent quality.
- Said quality of the UMAMI flavoring extract obtained according to the process of the invention can be evaluated, for example, in the degree of hydrolysis of the peptides present in the product, which directly determines the organoleptic characteristics of the composition when used in the food processing. Additionally, the method of the invention is highly efficient in separating the flavoring extract from solid or discarded plant material. These improved characteristics are achieved by applying the steps and conditions of the method protected in the present invention.

- the present invention aims at a two-step “flash” (fast) hydrolytic process that allows the production of natural food flavorings with a high content of umami molecules.
- This process uses as raw materials different types of mushrooms and also mycelium of edible mushrooms. All these fungal materials have in common a high content of umami molecules and a similar cell wall structure, so they can be processed in a similar way.
- the process consists in its first stage in providing dry fungal material crushed irregularly to a particle size that must vary between 10 and 500 pm, especially between 50 and

- mycelium this corresponds to fungi that grow in the form of hyphae that together form the mycelium, without developing a fruiting body or mushroom.
- This mycelium is obtained through liquid fermentation.
- the resulting biomass is separated from the fermentation medium, crushed to break it up and then dried in a similar way to that indicated for mushrooms.
- the invention process begins. Where the first stage is to grind the fungal material irregularly, for example, in a mill that combines impact and shear principles.
- the final particle size of the flour and the regrind must be heterogeneous and range between 50 and 500 ⁇ m, especially between 50 and 400 pm, and preferably between 100-300 pm. This condition must be fulfilled in more than 80% of the flour particles, preferably in more than 90%.
- the irregular flour obtained in the first stage is subjected to 2 successive enzymatic digestions, for which the flour is mixed with water to a concentration of between 50 and 200 g/L of substrate, preferably between 50 and 100 g/L, in a reactor with constant stirring and anaerobic environment given, for example, by saturation with gaseous N2. Maintaining anaerobic conditions is crucial for the organoleptic properties of the composition of

- Filtration can be carried out by any system known in the state of the art, such as a horizontal hydraulic filter press or a vertical filter press, for example. Filtering has an estimated operating time of 30 to 60 minutes, and is conveniently carried out at a temperature between 30-50oC, until the liquid phase is completely separated and a discard dry cake is obtained.
- the liquid phase is then subjected to enzyme inactivation, which at the same time makes it possible to eliminate possible contamination with microorganisms or cells of the processed fungus. Stopping the enzymatic activity is essential so that the product does not interact unduly with the food with which it will be used, preventing it from modifying its polysaccharide or protein content, and concomitantly its organoleptic properties.
- sonication of the liquid phase is performed, in conjunction with a moderate increase in temperature. This produces sonoporation, where cell walls and membranes are perforated and cavitation generates shock wave differences and shear stress.
- This sonication at moderately high temperature is carried out for a time of between 10 and

- Enzymatic digestion was carried out at 50°C and 500 rpm for 4 hours.
- msg-like molecules were quantified by analyzing the samples of chemical digestion and enzymatic digestion, using liquid chromatography coupled to a mass spectrometer (LC/MS) equipped with a quadrupole. This technique makes it possible to quantify the free amino acids present in the sample (mg free aas/g sample).
- LC/MS mass spectrometer
- the enzymatic and chemical digestion processes were carried out with the aim of degrading the cell content and releasing free amino acids, specifically msg-like molecules such as aspartic acid, glutamate and 5'-ribonucleotides. Once these amino acids were released, their content was analyzed using two methods: liquid chromatography coupled with Mass Spectrometer (LS/MS) and spectrophotometry using the OPA method. Chemical hydrolysis was used as a control to compare the effects of 1-step and 2-step enzymatic hydrolysis.
- LS/MS Mass Spectrometer
- the degree of hydrolysis (GH) was determined in each case in triplicate in order to complement the previous result.
- the %GH average was 55.9% for the one-step hydrolysis and 81.6% for the two-step hydrolysis according to the method of the invention. That is, the efficiency of the process improves practically by 50% when carrying out the hydrolysis as determined by the method of the invention.
- 1 step has a lower organoleptic evaluation in terms of flavor power and less detection of aromas and flavors with mushroom notes compared to the 2-step process of the invention (Table 4). It can be seen that the score of sample 4532 (umami with 2-step digestion of the invention) is higher than the score of sample 4886 (umami with 1-step digestion) in both salty and umami flavors. In addition, sample 4886 presents a higher degree of acidity as indicated by the judges, which is an important point to consider in any matrix.
- the application of enzymes in the hydrolysis stage directly influences the amount of umami molecules that are obtained at the end of the process.
- it favors the obtaining of umami molecules and improves the organoleptic quality of the applied product in terms of flavor and aroma. This is evidenced in the comparison of msg-like molecules between one process or another, compared to a hydrolysis chemistry.
- enzymatic digestion in two steps allows obtaining a higher degree of hydrolysis (GH) and increasing the amino acid content.
