Due to growing health concerns in recent years, much attention has been paid to the physiological functions of food.

(AS ANTIOXIDANT ACTIVITY OR ANTI-AGING)

FUNCTIONAL FOODS THEY ARE FOOD AGENCY FUNCTION. COUNTRIES LIKE JAPAN, COUNTRIES OF THE

EUROPEAN UNION AND THE UNITED STATES HAS DONE TO DEVELOP FUNCTIONAL FOOD STUDIES

.

BIOACTIVE PEPTIDES first reported Mellander of bioactive peptides

generated from protein food. a wide range of bioactive peptides are in

protein milk.

ACE INHIBITORS AND PEPTIDES ANTIHYPERTENSIVES. peptides studied the most are the ace

inhibitors these have the capacity to prevent hypertension; these could be used as a functional food additives.

ACE dipeptidyl carboxypeptidase that is widely distributed in the fabric of mammals.

ectoenzyme as a dominant in the system renin-angiotensin ACE playing an important role controlling blood pressure.

PEPTIDE OPIOIDS these peptides have an affinity for opioid

receiver. s. effects have nervous. influences gastrointestinal function have a n-terminal sequence. is generated from hydrolysis of milk casein

specific. also found in hydrolysis wheat gluten.

PEPTIDES IMMUNOMODULATING studies have shown that are within the

sequence immunomodulatory milk protein. these affect the immune system and cell

proliferation response. infections of mice avoided. also found in hydrolysis of soybean and rice. not informed of any arising inmunomodulator

peptide protein meat.

ANTIMICROBIAL PEPTIDES isolated protein milk and eggs generated

from casein by digestion chymosin. protected mice staphylococcus aureus y

candida albicans.

PEPTIDE PREBIOTIC probiotic bacteria improvement activity such

as intestinal lactobasillus. obtained by enzymatic hydrolysis of milk,

showed the growth stimulation of lactic acid bacteria.

however are indicative major growth factors are the remains of sugar (glycosylated peptides) unglycosylated peptides found recently.

BINDING PEPTIDES MINERALS peptides derived from milk by enzymatic

hydrolysis of minerals used as hunters, sites across union and non-specific specific effective as a result of mineral absorption.

PEPTIDES ANTITHROMBOTIC based on the mechanism of blood

coagulation is very similar to milk. coagulation of milk is produced by interaction

with casein clotting enzyme. the interaction of blood fibrinogen with

thrombin.

PEPTIDES HYPOCHOLESTEROLEMIC protein diet (soybean and rice) has been shown that is for the decrease

serum cholesterol. hydrolysates of β-lactoglobulin mirror the peptide reduce the solubility

micelar cholesterol e inhibits the absorption of this.

ANTIOXIDANT PEPTIDE Neutralization and LESS FREE RADICALS ARE

PRODUCED THROUGH DIETARY INTAKE AS FRUITS AND VEGETABLES.

IDENTIFIED APARTIR OF SOYBEAN LAPROTEINA.

GENERATION OF MEAT PROTEIN PEPTIDES protein bioactive sequenced. those are inactive or incomplete sequences

within parent protein. activity reported that is generated ace

inhibitor protein a partier meat. beyond the gastro intestinal intake there are

several ways in which the peptides generated from meat protein as will describe.

AGING OF MEAT the content of peptides increase in meat

during postmortem aging through changes in these levels increase oligopeptide during storage.

storage makes protein meat by Sean hydrolyzed proteases endogenous.

not been any report of a generation during aging peptides bioactive meat, but the storage of meat a 4 ° C bioactive peptides are produced.

ANTIHYPERTENSIVE PEPTIDES DERIVED FROM MEAT PROTEINS

( ACE Inhibitoty)

ACE Inhibutory peptides generated from meat proteins, including peptides generated in fish muscle proteins have relatively common.

- Anthypertensive Activity of ACE inhibitory peptides.

- Stucture- Activity relationShips

PROMISING BIOACTIVE PEPTIDES FROM MEAT PROTEINS

• Opioid peptides• Antioxidative peptides• Peptides with Organoleptic properties

Conclusions and Future Prospects

Although bioactive peptides, such as ACE inhibitors, have not yet been utilized in the meat industry, meat product with such activity could open up a new market. Because several food products containing antihypertensive peptides, such as sour milk and soup products. have been marketed for hypertensives in Japan.

In the dairy industry, the main approach for improving the beneficial physiological properties of products has been discussed in the field of meat science and industry.
