    Study Notes

    Halal Control Points in Enzyme Productions

    • Halal control points for conventional process for extracting enzymes from animal organs:
      • HCP1: Animal Organs - Organs should be from halal-slaughtered animals to be universally acceptable.
      • HCP2: Preparation of Tissues for Extraction - Equipment must be thoroughly cleaned to avoid contamination from previous runs.
      • HCP3: Enzymes might not be present in the tissues in soluble form and therefore need to be released or made soluble to increase the yield.
    • Halal control points for enzyme production in a conventional fermentation process:
      • HCP1: Raw Materials for Growth Media - Raw materials used should be halal acceptable and not modified or processed by using porcine or other non-halal enzymes or materials.
      • HCP2: Origin of Cultures - Microbial cultures, yeast, algae, or bacteria can be indigenous or genetically engineered; genetic material from halal species of animals and all plant sources are generally acceptable.
      • HCP3: Processing aids such as antifoam should be free of prohibited materials, especially derivatives from pork fat.
      • HCP4: All materials used as growth media and in the preparation of the mother culture should be halal.
      • HCP5: Standardization Ingredients - Preservatives, emulsifiers, and other standardizing materials must be from acceptable sources.
      • HCP6: Enzymes should be packed in acceptable containers and labeled properly with halal markings.

    Classification of Enzymes

    • Enzymes are classified into six categories:
        1. Oxidoreductases - catalyze oxidation reactions, such as the conversion of alcohol.
        1. Transferases - catalyze the transfer of a group of atoms, from one molecule to another, such as the transfer of amino groups.
        1. Hydrolases - catalyze the reaction of a chemical with water, breaking up large molecules into smaller ones, such as the hydrolysis of proteins.
        1. Lyases - catalyze reactions producing or resulting in double bonds, for example, conversion of sugars.
        1. Isomerases - catalyze the transfer of groups on the same molecule, resulting in a new structure for the molecule.
        1. Ligases - enzymes catalyze the joining of molecules to form larger molecules.

    Uses of Enzymes in Food

    • Enzymes are used in various food industries, including:
      • Bread making - convert sugars to alcohol and carbon dioxide, strengthen gluten network, and modify triglycerides.
      • Cheese making - help milk to coagulate, accelerate cheese ripening, and reduce allergic properties of dairy products.
      • Juice industry - increase yields, improve color and aroma, clarify juices, and extract essential oils.
      • Vegetable oil extraction - allow oil to be extracted into a water solution, avoiding the need for an organic solvent, and modify oils to improve nutritional value.
    • Examples of enzyme uses in food:
      • Glucose/maltose production
      • Protein hydrolysis (trypsin, pronase, pepsin, and prolidase)
      • Fruit juice extraction (pectinases and amylases)
      • Vegetable oil extraction

    Halal Issues in Enzyme Production

    • To label or not to label enzymes - enzymes are usually used as processing aids and functional catalysts, and are usually deactivated in the final product, but sometimes remain active and are listed on the finished product label.

    Enzyme Production and Halal Control Points

    Conventional Fermentation Process

    • Halal control points in enzyme production involve several key steps, including the use of halal-acceptable media in growth media, ensuring the origin of cultures is halal, and using processing aids that are free of prohibited materials.
    • Raw materials used in growth media should not have been modified or processed using porcine or non-halal enzymes or materials.
    • Indigenous sources of microbial cultures are acceptable, but if genetically modified, the source of genetic material becomes important, and genetic materials from haram animals should be avoided.
    • Preservatives, emulsifiers, and other standardizing materials must be from acceptable sources, and alcohol may be used as a preservative if below 0.5% by volume in the final enzyme preparation.

    Enzyme Extraction from Animal Organs

    • Enzymes can be extracted from animal organs such as porcine, bovine, or ovine, but organs from pig sources are not acceptable for halal production.
    • Organs should be from halal-slaughtered animals to be universally acceptable, and may need to be harvested from regions where Muslims perform animal slaughter.
    • Before using equipment for extracting halal enzymes, it must be thoroughly cleaned to avoid contamination from previous runs.
    • Chemicals used to release or make soluble enzymes must be suitable for halal production.

    Enzyme Uses in Food Industry

    • Enzymes play a vital function in the regulation and performance of living cells, speeding up reactions and catalyzing specific reactions.
    • Enzymes have been used for many centuries in the food industry, with major uses including cheese making, baking, fruit and vegetable processing, and food ingredient production.
    • In bread making, enzymes convert sugars to alcohol and carbon dioxide, strengthen the gluten network, and modify triglycerides.
    • In cheese making, enzymes help milk coagulate, accelerate cheese ripening, and reduce allergic properties of dairy products.

    Classification of Enzymes

    • Enzymes are classified into six categories, with examples including glucose/maltose production, protein hydrolysis, fruit juice extraction, and vegetable oil extraction.

    Enzyme Production Process

    • Enzyme production involves harvesting, where solids (biomass) are removed by filtration or centrifugation, leaving the enzyme in the solution (broth).
    • The broth is then evaporated to concentrate the enzymes, which can be further purified by ion exchange before processing into powders, liquids, or granules.

    Enzymes in Halal Food Productions

    • Enzymes play a vital function in regulating and performing living cell activities, speeding up reactions and catalyzing specific reactions.
    • Enzymes have been used in the food industry for centuries, with evidence of their use in cheese making dating back to 800 B.C.

    Uses of Enzymes in Food

    • Major food industry uses: cheese making, baking, fruit and vegetable processing, and food ingredient production.
    • Enzymes are used in sugar production, starch processing, protein hydrolysis, juice extraction, and oil modification.
    • In baking, enzymes improve bread quality, freshness, and shelf life by converting sugars to alcohol and carbon dioxide, strengthening gluten networks, and modifying triglycerides.
    • In cheese making, enzymes help milk coagulate, accelerate cheese ripening, and reduce dairy product allergenicity.

    Classification of Enzymes

    • Enzymes are classified into six categories:
      • Oxidoreductases: catalyze oxidation reactions, such as alcohol conversion.
      • Transferases: catalyze group transfer between molecules.
      • Hydrolases: catalyze chemical reactions with water, breaking down large molecules into smaller ones.
      • Lyases: catalyze reactions producing or resulting in double bonds.
      • Isomerases: catalyze group transfer within the same molecule.
      • Ligases: catalyze molecule joining to form larger molecules.

    Bioengineered Enzymes

    • The identification and understanding of DNA led to gene splicing and the development of bioengineered enzymes.
    • Bioengineering methods employ growth and production of enzymes using selected microorganisms and submerged fermentation.

    Halal Control Points in Enzyme Productions

    • Halal control points for conventional enzyme extraction from animal organs:
      • HCP4: Ingredients for standardization should be halal.
      • HCP5: Labels should be marked properly with halal markings.
    • Halal control points for conventional fermentation process:
      • HCP1: Raw materials for growth media should be halal.
      • HCP2: Microbial cultures should be from halal sources.
      • HCP3: Processing aids should be free of prohibited materials.
      • HCP4: Materials used in growth media and mother culture preparation should be halal.
      • HCP5: Standardization ingredients should be from acceptable sources.
      • HCP6: Enzymes should be packed in acceptable containers and labeled properly with halal markings.

    Issue: To Label or Not to Label Enzymes

    • Enzymes are usually used as processing aids and functional catalysts, but may not be included on labels if deactivated in the final product.
    • However, enzymes might remain active in cheese and bakery products and are listed on the finished product label.
