The role of women in the fishing industry

VIDEO ON THE TOPIC: Amazing Automatic Fish Processing Line Machines Modern Technology - Big Catch in The Sea

Nowadays, there is a growing interest on how to utilize fish materials remaining from the main production and considered as unappropriated for a direct human consumption. There are numbers of possible solutions to recover valuable nutrients from that matter and one of the most efficient is the production of fish protein hydrolysate.

This article is devoted to overview existing information about the production of dried fish protein hydrolysates with a focus on dehydration process during production and equipment used for moisture removal. Drying step of the production is considered as the most energy demanding and, therefore, described in detail. Questions considering energy demands of the drying are highlighted in the article together with the proposals for the improvement of energy efficiency.

This work also describes source of the raw material, the main steps of the technological scheme with the equipment used and valuable information on the intermediate state of fish protein hydrolysate between the process operations. Fish and marine products are one of the most used protein sources for human consumption. However, a big part of the catch is at its best utilized for production of cheap by-products such as fish flour, fish oil or animal feed or just wasted unused.

At the same time, a growing amount of fishery and, consequently, of fishing wastes demands efficient solutions for their utilization since they are a good nutritional source, which is highly underestimated. Fish protein hydrolysates FPH are a product made from fish or fish material by the method of protein hydrolysation breakage of proteins from which fish tissues are constructed into smaller parts—peptides and finally into amino acids.

Thus, FPH is a mixture of broken proteins Damodaran et al. FPH are reported to have a number of improved properties compared to the protein of origin which are namely improved functional properties He et al. FPH is produced in two forms: liquid and dried. FPH in a liquid form is highly unstable for a long-term storage and, moreover, it is difficult to be transported. Thus, dried FPH is preferable due to a longer shelf-life, easier storage and transportation. Nevertheless, at the same time, the removal of such a big amount of water from liquid FPH is a difficult and costly task, which is one of the challenges of dried FPH production.

Thus, FPH has a huge potential use as a protein source for human consumption, but the step of dehydration demands a big energy supply and is, consequently, very costly. This article is devoted to highlight the main steps of moisture removal from FPH during the production, equipment used for the dehydration processes and possibilities to save or recover the used energy to cut energy costs. The very first task of the implementation of FPH technology is the analysis of main fishing sources, which are the most abundant and, possibly, underutilized.

The countries holding leadership in aquaculture were China with Thus, due to the abundance of aforeisaid species in worldwide fishing production, an attention must be paid on better utilization of a big amount of by-products rested after their processing. Global fish capture and aquacultural production in reached the values of From the amount used for human consumption, a big part was used as by-products or simply wasted.

According to Seafoodsource , if all fish globally are processed and all the by-products collected, the amount of 36 million tons left from the main fish processing would be available as raw material for further treatment. More precise distribution of fish by-products and unutilized wastes was published by Richardsen et al.

The rests from pelagic sector were almost totally utilized for fish flour and other fish products. Thus, underutilized and underestimated fishing rests from the main production can be processed to get FPH, which can increase efficiency of fish processing by redirection of the by-products for human consumption. This is both more profitable and environmentally friendly than using fishing resting material for fish meal.

In the case of FPH, the fishing industry avoids a two-stage circle of fishing rests consumption to feed animals, which will be consumed by humans and allows delivering a food resource straight to the final consumer.

In spite of economic benefits of FPH production, the main hindrance of complete by-product utilization is a logistic issue. There is a need for quick transportation of by-products in order to avoid spoilage. However, due to a general lack of well-organized model of collecting, storage and transportation, further utilization of fish by-products is complicated and available fish source may be even lost as wastes.

An example of successful collaboration between fish processing plants and by-product utilization facilities is Iceland Ocean Cluster, which is made up of nearly 70 companies located in a common building of around square meters SeaFoodSource Such models if realized globally may help better utilization of fish by-products due to easy transportation and high speed of fishing rest secondary processing.

Raw materials for FPH production can be both fish and fish left-overs. As it is seen from the table, some fluctuations and differences in the chemical content between different types of fish raw matter are possible due to the type of raw matter; however, similar fluctuations can be observed since seasoning, etc. In all cases, raw materials should be carefully evaluated at technological line in order to provide effective recovery of protein fraction.

Further in the article, the terms of raw material will be corresponded to any type of raw materials, generally used for FPH production, including both whole fish and fish by-products.

A principal technological scheme of FPH manufacturing is presented in Fig. The process starts from a takeover of raw materials. Water, chemicals or enzymes are added to minced raw material to obtain chemical acid or alkali or enzymatic hydrolysis correspondingly.

After a certain time, when a certain desired extent of hydrolysis is achieved, there is a need to stop the hydrolysation process by chemical or thermal treatments according to the hydrolysis method.

After termination of hydrolysis, the protein mixture is delivered to solid separation where liquid part is separated from the solids.

Then, a heating procedure can be applied if desired to treat the fish protein hydrolysate by temperature to reduce microbial activity pasteurization. In some cases when the final product has to have a certain quality, for example, to be used for biochemical purposes as a microbiological media, removal of salt can be provided.

After the protein mixture can be concentrated to remove some water before the drying procedure. It makes the process of drying more efficient due to the decreased quantity of water to be removed. However, at the same time, preliminary water removal by concentration needs additional equipment and energy to provide the dehydration process, thus, the need of such an extra treatment is decided by a producer for each certain case.

Hydrolysation of proteins can be generally provided by chemical acid or alkali treatment or by biochemical methods. Biochemical hydrolysis is provided by proteolytic enzymes, which are already present in fish tissues autolysis or by premixing of commercial enzymes in order to accelerate the process enzymatic hydrolysis.

Some literature on novel methods of fish protein hydrolysis is nowadays available in scientific publications, for example, the work of Hoeling and Volkov describing the method of hydrothermal extraction.

However, such methods need to be well evaluated before they can be used at an industrial scale. All methods of hydrolysation are held with one final purpose—extraction of protein part by the deformation of fish proteins into smaller parts peptides and amino acids and their further separation.

The peptides and amino acids, formed by protein degradation, have smaller molecular mass and can be absorbed by digesting system faster than proteins Di Pasquale It is a particularly important property for those, whose organism is weakened by a disease or who need a quick nutritional supply for examples, sportsmen.

Generally, water and fish material are mixed as However, there is also a possibility of hydrolysation process without water addition Himonides et al. Producers should evaluate the amount of added water for the hydrolysation step in order to provide a suitable extent of the protein breakdown and at the same time avoid extra costs for dehydration of unnecessary water fraction from FPH on the step of drying.

Hydrolysation is generally held in metallic tanks hydrolysators , which are in most cases constructed and installed by producers of FPH by themselves.

The hydrolysators should be constructed so, as heat is supplied to the tube shell of the tanks and, desirably, an agitation blade is installed into the tank to mix the hydrolysate mixture for uniform temperature and chemical distribution.

The amount of heat provided as well as the temperatures used for the hydrolysation depends on the type of hydrolysis, nature of raw material, used chemicals and other factors. During the treatment, one needs to know how the degradation of proteins should be extended. DH can be measured by a range of methods, which is overviewed by Kristinsson and Rasco and expressed as the ratio of broken peptide bonds to the total peptide bonds in the mixture per unit weight Eq.

DH is correlated with such functional properties of final FPH as solubility, emulsifying capability, foaming ability, fat absorption ability, and with such an important sensory property as bitterness He et al. A number of researches showed that bitterness of protein fraction increases with the decrease in peptide size Aliani and Eskin ; Aubes-Dufau et al. Slizyte et al. However, Slizyte et al. In such a case, the process of hydrolysis shall be well adjusted to avoid undesirable sensory properties of final FPH and, therefore, to control not only DH, but also the obtained length of protein fragments.

Chemical and enzymatic hydrolysation techniques allow a different amount of process control, which is extremely important for the choice of hydrolysation method. Chemical hydrolysis is provided by either acid or alkali. It is achieved by cleaving the bonds between different peptide groups in the protein sequence by chemical agents. Since this process is held at extreme working parameters high concentration of acid or alkali, high temperature , the process of hydrolysis in this case is almost uncontrollable.

As a result, the nutritional and functional properties of final FPH are reduced Loffler ; Webster et al. Thus, FPH produced by chemical hydrolysis has a very limited spectrum of utilization. Acid hydrolysis is more widespread than that by alkali.

Typically, fish is involved reacting with hydrochloric acid, but there are plenty of technologies involving sulfuric acid. The mixture is then neutralized to pH 6. The process of acid hydrolysation has several drawbacks such as high NaCl content which makes the final FPH inappropriate for some food and especially biochemical applications Kristinsson and Rasco ; Pasupuleti and Braun or the destruction of tryptophan which is an essential amino acid Jaswal ; Pasupuleti and Braun The use of alkali reactants, mainly sodium hydroxide, generally results in reduced functionality and nutritive value of final FPH.

Moreover, a range of substances, which are not absorbed or even toxic for human organism, can be created during alkali hydrolysis Kinsella and Melachouris ; Kristinsson and Rasco ; Lahl and Braun ; Linder et al. A number of amino acids as serine and threonine are destroyed during alkaline hydrolysis; however, tryptophan remains intact contrary to the acid hydrolysis Pasupuleti and Braun Despite described drawbacks, limited alkali hydrolysis is used in the fish processing industry to recover a range of proteins from fish material and fish protein concentrates in order to hydrolyze a valuable protein fraction and, thus, improve the functionality Kristinsson and Rasco ; Sikorski and Naczk ; Tannenbaum et al.

In this review, the attention is paid to the treatment when a specific enzyme or a mixture of enzymes is premixed to the hydrolysated slurry. This is more convenient and controllable method than that with autolytic enzymes due to a high variation in optimal conditions for each of enzyme in the autolytic enzymatic mixture and their variation influenced by species, season, gender, age, etc.

Kristinsson and Rasco Used for FPH production enzymes are of animal pepsins , plant papain, bromelain or microbial origin alcalase, neutrase, flavourzyme. Enzymes of microbial origin are considered as having greater pH and temperature stability He et al.

The application of enzymes allows obtaining a high-quality FPH avoiding such drawbacks as the developing of undesirable products of racemization as in a case of acid and alkali hydrolysis Gonzalez-Tello et al. Despite the aforesaid benefits, there are certain limitations when enzymatic hydrolysis is utilized. Among them are high costs of industrial enzymes, low yield, the need of a special treatment in order to deactivate the enzymatic hydrolysis, the difficulties of process control to obtain a certain molecular mass of the products of protein degradation and the bitterness of final FPH He et al.

However, recent researches with different enzymes used for FPH production revealed the mixture of papain and bromelain as a very promising solution for avoiding bitterness at the production of FPH from herring Slizyte et al. Exact values of relative bitterness as well as materials and methods of its evaluation can be found in the rapport of Slizyte et al.

The values in the table are derived from the Fig. To utilize hydrolyzed proteins as FPH, there is a need to separate protein fraction mainly from insoluble and fat fractions before the further dehydration. It is possible to be accomplished by a range of methods, mostly by centrifugation and plate and frame filtration.

In more advanced technologies, when a certain quality of final FPH is needed, the filtration of small chemical particles from the hydrolysation mixture can be provided microfiltration, ultrafiltration and nano-filtration from bigger to smaller particle separation correspondingly Pasupuleti and Braun In some cases, electro-membrane filtration is also utilized for FPH fractionation, for example, in order to fractionate active peptides from complex hydrolysates Suwal et al.

The temperature of purification mainly depends on the temperature of the delivered protein mixture and is not changed especially during the purification process by an additional heat supply. After the separation of protein part, the mixture is generally pasteurized at high temperatures in order to eliminate possible microbial contamination.

By using high throughput light and imaging technologies, the fish can also be automatically sorted according to species upon delivery. The technology could be compared to techniques used in medical scanning of the human body, however here it is being developed to meet with processing speed used in the fish industry.
