1、Evaluation of the efficacy, safety and acceptability of a fish protein

For 6 months, the centres received either FPi replacing 50 % of total proteins in the diet or standard protein. HAZ and WHZ were used to determine the effect on growth. Acceptability was determined by daily consumption, measured by weighing the servings before and after consumption.

2、Unlocking the potential of fish protein hydrolysates: Bioactive and

For the descriptive review, an exploratory search was carried out on Google Scholar, which considered articles published in the last 5 years (2019–2024) related to bioactivities, technofunctional properties, and applications of protein hydrolysates made from muscle and fish by-products.

To exert their activity, biopeptides should remain active after their inclusion into food matrices, its storage and subsequently after the human digestion process.

Fish protein hydrolysates as a health

Fish and fish products are important in diets worldwide because of their nutritional value, especially their easily digestible proteins with essential amino acids.

Enzymatic fish protein hydrolysates in finfish aquaculture: a review

Globally, the fish processing industries generate and discard a large volume of waste every year, estimated at up to 60% of the harvested biomass. This waste can be converted to value-added products such as fish protein hydrolysate (FPH) with the addition of various proteolytic enzymes.

Evaluation of the efficacy, safety and acceptability of a fish protein

Before recommending the use of this fish protein in the national nutritional programmes, we needed to determine the acceptability and safety of the fish protein with proper growth outcomes. Therefore, we conducted a community-based cluster-randomized trial in Lima.

Sustainable utilization of proteins from fish processing by

Within this context, the by-products of fish processing—comprising skin, viscera, scales, heads, bones, and fins—emerge as valuable reservoirs of proteins.

Review of fish protein hydrolysates: production methods, antioxidant

Protein hydrolysates are widely recognized as the most effective method for transforming these low-value raw materials into high-value products. Fish protein hydrolysate (FPH), sourced from various aquatic wastes such as bones, scales, skin, and others, is rich in protein for value-added products.

Fish Protein Hydrolysates: Bioactive Properties, Encapsulation and New

These bioactivities may vary depending on the conditions of hydrolysis, fish species, and fractionation and isolation of specific peptides.New technologies for the treatment of by-products can reduce process losses and achieve better results by cleavage of proteins.

The efficacy period of fish protein refers to the duration during which fish protein, after being absorbed by animals in feed, can exert its nutritional components and biological activity. This timeframe varies depending on factors such as the type of fish protein, the species of animal, and feeding conditions. Generally, the efficacy period of fish protein lasts for 1-3 days.

The efficacy period of fish protein is primarily influenced by the following factors:

1. Type of Fish Protein: Different types of fish protein have varying nutritional compositions and biological activities. For example, red-meat fish proteins are higher in protein but lower in fat, resulting in a shorter efficacy period; whereas white-meat fish proteins are lower in protein but higher in fat, leading to a longer efficacy period.

2. Animal Species: The absorption capacity of fish protein differs among animal species. Generally, larger animals like cattle and sheep have stronger absorption capabilities, resulting in a shorter efficacy period; smaller animals like chickens and ducks have weaker absorption capacities, leading to a longer efficacy period.

3. Feeding Conditions: Environmental factors such as temperature, humidity, and ventilation also affect the efficacy period of fish protein. High temperatures typically accelerate the breakdown and metabolism of fish protein, shortening its efficacy period; conversely, low temperatures slow down these processes, extending the efficacy period.

4. Feed Formulation: Other nutritional components in the feed formulation can impact the efficacy period of fish protein. For instance, adding appropriate amounts of minerals and vitamins can promote the absorption and utilization of fish protein, thereby extending its efficacy period; excessive fats and sugars, may reduce the efficiency of fish protein utilization, shortening its efficacy period.

5. Animal Health: The health status of animals also influences the efficacy period of fish protein. For example, sick animals may experience reduced appetite and digestive function, affecting their ability to absorb and utilize fish protein, thereby shortening its efficacy period.

Based on these factors, we can draw the

1. The efficacy period of fish protein generally ranges from 1-3 days. Within this timeframe, animals can fully absorb the nutritional components and biological activities of fish protein, achieving optimal growth outcomes.

2. To extend the efficacy period of fish protein, the following measures can be taken:

   • Select high-quality, nutrient-rich fish protein as feed ingredients.
   • Adjust feed formulations according to animal species and feeding conditions to ensure balanced nutrition.
   • Provide good feeding environments and management practices to maintain animal health.
   • Regularly monitor animal growth and promptly adjust feed formulations and feeding methods.

the efficacy period of fish protein is a complex issue that requires consideration of multiple factors. Through reasonable feed formulation, optimal feeding environments, and scientific management practices, we can effectively extend the efficacy period of fish protein, thereby improving animal growth performance and feed utilization efficiency.
