- Authors: Angela Dulce Cavenaghi-Altemio; Gustavo Graciano Fonseca, Adriane Macedo, Andressa Piccoli
  Abstract: Background: There are few studies on the evaluation of meat from hybrid sorubins. Objective: Thus, the aim of this work was to evaluate the physical, chemical, microbiological and sensorial characteristics of fillets of Amazon and real hybrid sorubins. Method: Proximate composition, instrumental colour, water holding capacity, cooking losses and shear force were measured. Microbiological analyses of the fillets were carried out for Salmonella sp. and Staphylococcus aureus to ensure food safety of the judges during sensory analysis. Results: Hybrid sorubim fillets presented an excellent quality, being classified in category A (lipids below 5% and proteins between 15% and 20%). There was no significant difference (p>0.05) between the evaluated fillets for several parameter: the average water holding capacities were 33.72 and 34.67%, the cooking losses were 14.93 and 13.41%, the shear forces were 2.21 and 1.74 kgf, and the luminosities were 49.61 and 45.04 for the fillets of Amazonian hybrid sorubim and real hybrid sorubim, respectively. Discussion: There was an evident relation between water holding capacities and shear forces. Amazonian hybrid sorubim fillets were more accepted due to their lower intensity of red. However, there was no sensorial difference between the hybrids, and both had an acceptance rate above 80%. Conclusion: It was concluded that the hybridization does not alter the sensory characteristics of the fish fillets.

Production of enriched cakes by apple pulp and peel powder and evaluation
of chemical, functional and textural properties
- Authors: Ahmadreza Hosseini; Fahimeh Pazhouhandeh
  Abstract:
  Background: Apple pomace is a by-product of the fruit juice industry and comprises peel, seed, stem, and pulp tissues. This by-product contains dietary fiber, polyphenols, vitamins, and organic acids that can benefit human health and have a high potential as a dietary source. Baked products are well-known food types to humans and have a key role in feeding people worldwide. Nowadays, enriched products such as bread, cakes, and biscuits are available in stores. Different studies worldwide have been done about applying fruit juice industry by-products in the bakery.
  
  Objective: This research aimed to evaluate apple peel (APE) and pulp (APU) powders separately as a partial substitute for wheat flour in cake production.
  
  Methods: Apple peels and pulp, separately produced as residual wastes of juicing, were dried for 3 hours in the oven (60°C). The dried pulp and peel were ground and sieved using a 60 µm mesh. In this research, chemical and physic-chemical analyses were performed according to AACC (Approved Methods of the American Association of Cereal Chemists) and standard food analysis methods. Textural characteristic was analyzed by a texture analyzer (Brookfield CT3-10 Kg, US) equipped with an aluminum probe.
  
  Results: Different levels of APE and APU powders (10, 20, and 30 %) were used to enrich the cakes. Wheat flour’s ash, fat, water, and oil absorption capacity were lower than APU and APE, whereas the moisture, protein, bulk density, and pH showed a reverse trend. Adding APU and APP to the cake formula increased total dietary fiber (TDF) from 4.14 % in the control sample to 27.71 % in the sample with 30 % apple peel powder (APE-30). The highest a* colorimetric parameter (redness) in the cake core was 3.82 in the APE-30 sample. The addition of APE and APU significantly increased the hardness, gumminess, and chewiness of the samples (p<0.05). APE-10 samples could improve the nutritional properties of the cakes without significant reduction (p>0.05) in overall acceptance compared to the control sample.
  
  Conclusion: The results of this research demonstrated that a partial replacement of wheat flour with apple pulp and peel significantly increased the dietary fiber, especially insoluble fiber, compared to the control sample. Apple pulp powder and apple peel powder have the potential for use in cake making as a good source of dietary fiber.

Total phenolic, monomeric anthocyanin content and antioxidant activity of
Berberis commutata Eichler fruits
- Authors: Carla Del Carpio-Jiménez
  Abstract: Background: Berberis commutata Eichler is a berry that grows in the Peruvian Andes and has been consumed in the Andes of South America since ancient times. The edible fruits have an intense purple color and are rich in anthocyanins and phenolic compounds that are available from February until May each year. The color of the fruits is a soft purple dye for natural fibers, and many birds use them as food. Objective: This study quantified the total phenolic, monomeric anthocyanin content and antioxidant activity of Berberis commutata Eichler berries. Methods: The total phenolic content was determined by the Folin-Ciocalteu colorimetric assay. Monomeric anthocyanin content was determined by the pH difference method, and the antioxidant activity was measured using the Brand-Williams method. Results: The total phenolic content was 7,490 ± 0.85 mg GAE/100g, and the monomeric anthocyanin content was 70 ± 0.03 mg/100g. The antioxidant activity of the berries showed a tendency to increase with B. commutata extract concentration; an EC50 of 0.91 mg/mL was calculated, indicating a high antioxidant power. Conclusion: Our results showed that B. commutata E. has both high total phenolic content and monomeric anthocyanins comparable to other superfruits and increased antioxidant activity, which means that it is possible to use this berberis species as a functional food.

Effect of the chemical composition of fluid foods on the rate of fouling
processing during sterilization
- Authors: Budianto Budianto; Zefky Okta Feri; Anik Suparmi; Muh Jaenal Arifin
  Abstract: Background: This research was motivated by the determination of the sanitation schedule in the heat exchanger area for some products (milk, avocado juice, and orange juice), as well as the inconsistency of the results of previous studies related to the chemical composition of the fouling layer. Objectives: a) to test the effect of raw material composition on the chemical composition of the fouling layer. b) to test microbial growth's effect on fouling's chemical composition (protein). Methods: mathematical derivation of the formation process of Resistant Dirt Factor (Rd) in the form of an Equation; ANOVA was used to test the effect of the dependent variable (protein) and predictor (microbial). Results: a) The composition of the raw material strongly influences the chemical composition of the fouling layer; b) There is a strong effect between microbial growth and protein content as a fouling composition (p<0.05). Conclusion: A strong influence between microbial growth and the composition of the fouling layer (protein) can close the research gap related to the inconsistency of previous research results (fouling layer composition), so there is no prolonged debate.

Fast Skeletal Muscle Troponin and Tropomyosin as a Dietary Source of
Antidiabetic and Antihypertensive Bioactive Peptides: An In Silico Study
- Authors: Jorge Andrés Barrero; María Alejandra Barrero, Angélica María González Clavijo, Claudia Marcela Cruz
  Abstract: Background : The nutraceutical properties of food hydrolysates rely on multiple biochemical interactions involving the modulation of enzymes and cellular receptors. Numerous bioactive peptides released from troponin and tropomyosin digestion have been identified. Their characterization has mostly been performed by hydrolysis catalyzed by proteases unrelated to the human digestive system. Objective: This study aimed to determine the bioactive profile of beef, pork, and chicken meat by analyzing the frequency and pharmacokinetics of biopeptides released from troponin and tropomyosin. Methods: In silico digestion and biopeptide release frequency were studied by three parameters; bioactive fragments release frequency (AE), frequency percentage (W), and mean occurrence (AS), all stated on the BIOPEP-UWM platform. Further on, hydrolysis end-products were screened based on gastrointestinal-absorption probability and pharmacokinetic profiling performed on SwissADME, SwissTargetPrediction, and ADME/Tlab bioinformatics web tools. Statistical analyses were performed using a one-way ANOVA test. Results: Dipeptidyl peptidase-IV (DPP-IV) and angiotensin-converting enzyme (ACE) inhibiting biopeptides exhibited the highest release frequency. Moreover, W and AS parameters showed no significant difference (p>0.05) between the myofibrillar isoforms assessed. Seven biopeptides were classified as highly absorbable and reported optimal drug-likeness compliance. Although biopeptides hold good pharmacokinetic properties, the therapeutic potency of biopeptides showed to be lower than those of DPP-IV and ACE-inhibiting drugs. Conclusions: Troponin and tropomyosin are rich dietary sources of bioactive peptides, mainly DPP-IV and ACE inhibitors. Digestion end-products are mainly dipeptides with optimal pharmacokinetic and drug-like properties, suggesting a potential therapeutic application in hypertensive and hyperglycemic disorders.
