6 Week-1 Mikrobiologi Pangan
Pendahuluan Definisi & Peranan Mikroorganisme Penyebab Kerusakan Mikroorganisme dalam Bidang Pangan Produk Fermentasi

7 PENDAHULUAN

8 TIME LINE 1975-Now Era Pasca Antibiotika Era Pasteur Era Antibiotika
1940 1960 1975 1975-Now Before 1865 Era Pasca Antibiotika Era Pasteur Era Bioteknologi Modern Era Antibiotika Era Pra-Pasteur

9 Era Pra - Pasteur Pembuatan Pangan Fermentasi tradisional, contoh:
Minuman beralkohol (Bir, Anggur, Sake), Keju, Yoghurt, Tempe, Oncom, Acar, Pembuatan Tempe Ciri Utama: Pemanfaatan / pendayagunaan mikroba untuk pengawetan dan atau pembuatan makanan/minuman

10 Era Pasteur Pasteur : Peran mikroorganisme dalam industri fermentasi
Pengembangan Industri Fermentasi Pembuatan Etanol Pembuatan Butanol Asam Organik Perlakuan Air Buangan

11 Era Antibiotika Pembuatan Penicillin Vaksin Virus
Teknologi Kultur Sel Hewan

12 Era Pasca - Antibiotika
Asam – asam Amino Elusidasi Struktur DNA Protein Sel Tunggal Enzim untuk detergen Produk farmasi (interferon,hormon, vaksin) Teknologi Rekombinan DNA

13 Era Bioteknologi Modern
Rekayasa Genetika Zat Antibodi Monoklonal Hormon Insulin Buatan Hormon Pertumbuhan Ikan tuna

14 Mikrobiologi - Bioteknologi
Apa kaitan antara mikrobiologi dengan bioteknologi ??? Mikrobiologi pangan termasuk dalam bioteknologi era tradisional/lama. Mikrobiologi pangan  Era Pra-Pasteur

15 DEFINISI & PERANAN

16 Definisi Mikrobiologi Pangan  Ilmu yg mempelajari tentang peranan mikoorganisme pada bahan maupun produk pangan. Food is an ecosystem and microorganisms play a key role in the stability of that ecosystem. Microorganisms are introduced to the food ecosystem from the soil, harvesting, handling, storage, and packaging.

17 Peranan Mikroorganisme
Positif : 1. Pangan fermentasi 2. Produser metabolit 3. Host Cell Negatif : 1. Food Spoilage 2. Food borne diseases

18 Poin Penting Penerapan agen biologis (mikroorganisme) pada produk pangan fermentasi  Beer, Wine, Yoghurt, Keju, Tempe, Roti, Kefir, Kecap, dll. Penerapan bagian/metabolit m.o (enzim, antibiotik, hormon, pigmen, dll) Pencegahan terjadinya kontaminasi m.o Pencegahan terjadinya infeksi m.o

19 MIKROORGANISME PENYEBAB KERUSAKAN

20 Food Spoilage Smell bad, taste bad, look bad Probably are not harmful
microorganisms that cause food spoilage compete with pathogens in the case of food spoilage vs. pathogens, the spoilers are winning evidence is obvious, though I wouldn’t eat anything that smelled or looked like that

21 Food Spoilage Spoilage: bad food microbiology
undesirable changes to food; sour milk, moldy bread preservatives and refrigeration inhibit the growth of microorganisms Moldy Spam

22 Foodborne Intoxication
illness from microbial exotoxin microorganism does not cause the illness, the toxin released by the microorganism does common exotoxin producing microorganisms Staphylococcus aureus Clostridium botulinum

23 Foodborne Infection requires consumption of microorganism
symptomatic about 1 day following ingestion of contaminated food common foodborne infecting microorganisms Salmonella and Campylobacter poultry product infections Escherichia coli 0157:H7 undercooked hamburger Campylobacter Salmonella

25 MIKROORGANISME DALAM BIDANG PANGAN

26 Food Microbiology Fermentation: good food microbiology
food that have been intentionally altered such as sour cream, cheese, beer any desirable change a microorganism makes to food

27 Microorganisms in Food Production
using microorganisms for food production has been done for thousands of years cheese, yeast, beer microorganisms used in food often produce an acidic by-product as a result of metabolism can inhibit growth of many spoilage microorganisms can inhibit growth of many foodborne pathogens Yeast cells

28 Some Microorganisms Involved in Fermentation Procesess
