-Food Quality is a term which can refer to a number of things: the extent to which food contains the nutrients that match the kind and quantity of the healthy needs in the person eating the food the extent to which the food is attractive in look & taste the extent that food is free from pathogenic bacteria & undesirable components such as insecticides & antiseptic residues, and so on FOOD QUALITY 1 .
Blend of characteristics/ attributes which usually differs from a single unit to a different 2 . Wholeness of features/ characteristics of your product that bear upon its capability to satisfy a given need: Needs: Safety Simplicity Availability Economics.
Maintainability Environment Reliability several. Uniformity, persistence and conformity to a given standard or perhaps specifications 4.
A press release of the particular user desires & the particular manufacturer can provide 5. “Fitness for use, “satisfaction level of costumers Different ways of Describing Quality 1 . Fast providing brand of a food product might be labeled as “Extra Special Quality 2 . Goods that are sold abroad might be termed as “Export Quality a few. Some consumers may gauge quality with regards to brand recognition 4. In the large producer’s point of view, top quality may mean product trustworthiness.
Small suppliers ” trustworthiness may not be a concern, their concern is more on sell in the products. five. In a seller’s market condition, product availability means top quality Quality of Food is founded on the following: 1 ) Raw materials ” the caliber of finished system is dependent on the quality of raw material 2 . Physical quality ” food top quality detectable simply by our senses can be categorized into three or more: ” physical appearance ” structure ” flavour 3. Microbiological quality ” raw materials and goods should be free of toxin-producing microorganism QUALITY CONTROL Is Doing Items Right.
INITIALLY AND EVERYTIME Quality Control can also be understood to be a. repair of specified finished product qualities every time it is manufactured m. efficient charge of raw material and of production process c. object of quality control is to develop a quality which: ” complies with the buyers; as affordable as possible; could be delivered over time to meet delivery requirement d. is the function or number of duties which will must be performed throughout a company in order to achieve its top quality objectives Levels of Quality Control 1 . Set the specifications.
a. Exactly what the customer or marketplace expects m. Price when product can be sold c. Delivery date d. Capability of equipment/ machines e. Capacity for available inspection and check equipment 2 . Prepare to have a. Decide how to process the item b. Determine what tools to use c. Specify the standard of raw materials and possible suppliers d. The in-line workers e. Program inspection and in-process top quality control a few. Actual Processing/ Manufacture some. Correction of quality problems 5. Offer long-term top quality control organizing Defects in Foods Defect.
” noticeable deviation via product specs that makes product less fit, or unfit for consumption ” deficiency of something necessary or required; or an imperfection ” can occur singly or like a composite of several deviations Sources: 1 . Raw materials ” biological system that deteriorates with time. 2 . Staff ” staff’s commitment for their work and their ability to conduct their activity well. three or more. In-process challenges ” quality loss as a result of poor comprehension of processing methods and make use of inadequate machines ” due to lack of personnel training Evidences of Defects Prevention Program: 1 .
Quality raw materials 2 . Reduction of processing loss 3. Drop in the volume of rejects Precisely what is HACCP? 5. Hazard Examination and Important Control Points * Prevention-based food security system 5. A systematic way of the id, assessment of risk, and severity and control of biological, chemical and physical risks associated with a particular food creation process or perhaps practice (US FDA CFSAN, 2000) Two Important Terms * PROBLEMS * CRITICAL CONTROL FACTORS HAZARDS 5. Any natural, chemical, physical property which may cause a great unacceptable consumer health risk. * three or more major hazards.
* Neurological * Chemical * Physical -Biological Risks * These organisms are usually associated with individuals and with raw items entering the meals manufacturing facility. 5. Bacteria, foodborne viruses, organisms * Good examples: * Salmonella, Listeria, Staphylococcus * Hepatitis A and Norwalk Malware * Trichinella -Chemical Risks * Substance contaminants could possibly be naturally occurring or perhaps may be added during the control of the foodstuff. * Natural Chemicals 5. Toxins coming from molds (aflatoxin) * Allergy Proteins * Added Chemical substances * Agricultural chemicals 2. Industrial chemicals.
* Substances: Flavors boosters, colors, preservatives -Physical Risks * Overseas and extraneous materials 5. Foreign Materials * Something that does not naturally occur in the food material * Hair, hands (fingernails), plastic material, metal filings, jewelry, gum etc . 5. Extraneous Elements * Anything that naturally occurs in the food but really should not be there 5. Pits, seeds, peel, comes Critical Control Points * CCP’s * Process stages in specific foodstuff systems in which loss of control can result in an unwanted health risk 7 Guidelines of HACCP: 1 . Determine hazards inside the system installment payments on your
Determine important control factors 3. Establish critical limits 4. Set up monitoring methods 5. Set up corrective actions 6. Build verification process 7. Establish record keeping and documentation procedures Very good Manufacturing Practices (GMP) ” set of hygienic guidelines and control to get compliance to ensure safety and wholesomeness of foods. Concerns: 1 . Workers 2 . Grow and environment 3. Hygienic operation 5. Sanitary services and control 5. Gear and products 6. Process and control Cleaning and Sanitization Washing ” surgery that will take out at least 90% from the soil or perhaps dirt.
Sanitization ” using sanitizers Cleanliness ” over-all cleanliness of the surroundings or perhaps anything that encompases the food Steps: a. take away the debris n. pre-rinse c. application of cleaning aids d. post wash e. desinfection rinse FOOD SPOILAGE as well as DETERIORATION Meals Spoilage/Deterioration -Includes losses in organoleptic desirability, nutritional value, protection and aesthetic appeal of the food -Food is usually subject to physical, chemical and biological destruction, which proceed hand in hand Origin Factors: -Temperature (heat and cold) 2. Oxygen 5. Moisture 2. Light & radiation * Time.
2. Natural food enzymes 5. Micro- and macro- organisms * Industrial contaminants * Some foods in the presence of other foods In general, damage is slowed up when the foodstuff is reduced moisture, high in salt/sugar or acid Shelf-life and Going out with of Food Shelf-life ” is the time it takes a product to decrease to an suitable level ” time a product or service remains saleable MAQ ” minimum appropriate quality intended for the product has to be defined by manufacturers or retailers Real length of shelf-life is dependent on a number of elements: 1 . processing methods 2 . packaging.
3. storage circumstances Dating ” provides customers some indication of the shelf-life or quality of the goods they acquire Type of code dates incorporate: * time of make (“pack date) * day the product was displayed (“display date) 5. date by which the product needs to be sold (“sell by date) * previous date of maximal quality (“best applied date) 5. date over and above which the product is no longer satisfactory (“use by date or “expiration date) Major Causes of Food Destruction -often the following factors will not operate in isolation -as such, powerful preservation must eliminate or minimize all of these factors within a given meals to prevent/minimize deterioration 1 )
Growth activities and actions of organisms ” Bacterias, yeasts, molds ” Microbial growth competition * Circumstances necessary for microorganisms to grow: * Source * Meals residue * Moisture * Time * Temperature * Invasion of microorganisms is caused by contamination which may be avoided by sanitary procedures and right processing types of procedures and packaging * Only some microorganisms might cause disease or perhaps food spoilage, others are helpful for food processing 5. Food paid for diseases ” special sort of deterioration which may or may not adjust a food’s organoleptic homes 2 . Pests by bugs, parasites and rodents.
2. Insects destroy 5-10% total annual grain plants (US), far away (50%) * Parasites Examples of Parasites: 5. Trichinella spirallis, enters hogs eating raw food waste products; nematodes, permeates hog intestinal tract and find method into the pork ” Entamoeba histolytica, parasite associated to raw man excrement and will infect plants when organic human excrement is used since fertilizer -can cause amoebic dysentery * Rodents ” can ingest large quantities of food and they may contaminate food by filth they bring ” can easily spread illnesses like: Salmonellosis Leptospirosis Typhoid fever Problem 3.
Activities of foodstuff enzymes and other chemical reactions within food by itself * meals enzymes happen to be natural in healthy, uninfected foods * activity is definitely intensified right after harvest 5. activity may also be desirable * can be inactivated by temperature, chemicals and irradiation, etc . 4. Improper temperatures (heat and cold) for a provided food 5. heat and cold ” can cause degeneration if not controlled; 10-38C (normal operating temperature) * excessive high temperature: denatures healthy proteins, breaks emulsion, dries out food simply by evaporation and destroys vitamin supplements * out of control cold: FAV are iced ” staining, changes in consistency.
” may break emulsion such as in milk ” denatures dairy protein ” chill harm 5. Possibly the gain or loss of moisture ” Aw and Moisture Articles (needed by simply microorganisms for growth through different chemical reactions) 6. Reaction with oxygen * can cause substance oxidation of nutrients, colors, flavors 5. required for growth of some organisms * may be excluded by vacuum the labels, addition of oxygen scavengers 7. Mild * can destroy several vitamins (riboflavin, A and C); deteriorates many foodstuff colors 2. in milk ” can cause “sunlight flavors (induced fat oxidation and changes in CHON) * May be minimized by simply opaque presentation 8.
Period * quality decreases over time * object is to keep and record freshness of foods 2. to extend shelf life ” adequate control, packaging and storage Spoilage of Different Types of Foods 1 . Bread Mildew: results in discoloration of the loaf of bread Ropiness: smooth and gross to feel, caused by sporeforming bacteria, Bacillus subtilis and Bacillus licheniformis 2 . Honies * substantial sugar(70-80%) and acidic (pH= 3. 2-4. 2) * chief reason behind spoilage: Zygosaccharomyces mellis three or more. Candy 2. not be subject to microbial spoilage (high sweets and low MC) 5. except delicious chocolate with smooth centers (burst and may explode), cause by simply Clostridium spp.
4. Vegetables and fruit * spoilage due to physical factors, action of their enzymes, microbial actions or combination of these brokers * microbial spoilage can be due to plant pathogen and saprophytic organisms * standard type of spoilage: * microbial soft rot (Erwinia caratova) * grey mold decay (Botrytis cinerea) * rhizopus rot (Rhizopus nigricans) 5. anthracnose (Colletotrichum lindemuthianum) 2. blue mold rot (Penicillium) * dark-colored mold decay (Aspergillus niger) 5. Fresh fruit juices * acid (pH installment payments on your 4-4. 7), all consist of sugars (2-17%) * molds.
* liquor fermentation six. Sauerkraut 2. inferior quality due to abnormal fermentation: high temp; low temp; too long fermentation * surface spoilage (destroy the acidity, permit various other microorganisms to grow, treatment, darkening and bad flavors) 7. Eggs * Flaws: cracks, leakages, dirty locations on the exterior (will favor spoilage on storage) * Alterations caused by microorganisms during storage space: * green rot (Pseudomonas fluorescens) giving green colour of the egg white * colorless get rotten (various microorganisms): yolk can be affected 8. Meat and Meat Products.
* uncooked meat: enzyme, microorganisms, oxidation process of fats * beef: moderate amount of autolysis is desired to tenderize it, excessive autolysis (souring) 5. general concepts: * Factors influencing attack of damaged tissues by microorganisms: * load in the gut of the creature * physical condition of the dog before slaughter * method of killing and bleeding Elements affecting the growth of organisms in beef * kind and sum of microorganisms * physical properties of meat (exposed area, grinding) * chemical properties of the meat (MC, protein, CHO, pH).
* availability of fresh air * heat General types of spoilage in beef * cardiovascular condition: * surface gook, goop, guck, gunk, muck, ooze, sludge (Pseudomonas, Achromobacter, Streptococcus, Leuconostoc, Bacillus, Micrococcus) * surface discoloration (Serratia marcescens, Pseudomonas, Micrococcus/Flavobacterium) 2. oxidation of fats * stickiness (molds) * whiskers (Thamnidium elegans, Mucor mucedo) * anaerobic condition: * putrefaction, souring Cured meat: addition of nitrates lessen growth of microorganisms, spoilage same with fresh if stored wrongly 9. Seafood and Other Seafoods.
* spoiled by autolysis, oxidation or perhaps bacterial activity * elements influencing spoilage: * kind of fish: toned fish or round seafood, fatty seafood deteriorates more quickly * condition of fish when caught: worn out spoil quickly * kind and level of contamination of the seafood flesh with bacteria 2. temperature * use of a great antibiotic ice or drop evidences of spoilage: 2. brightness ends and filthy, yellow discoloration appears * slime for the fish boosts * sight gradually sink * gills: light red to grayish yellow * softening from the flesh.
2. development of off-colors 10. Poultry * key source of spoilage: bacteria * bacterial development takes place for the surface and any cut surfaces and the decomposition items diffuse gradually into the meats * off-odor is observed when the microbe count reaches 2 . a few x 106 cfu/cm2 2. Psuedomonas and Achromobacter 2. Micrococcus, Flavobacterium and Achromobacter * Surface area of skin area becomes gook, goop, guck, gunk, muck, ooze, sludge, acid/sour smell 11. Milk Chief form of spoilage: * Souring or perhaps acid development * Gas production * Proteolysis 5. Ropiness 5. Surface or throughout the milk.
