Penelitian ini bertujuan untuk mengetahui karakteristik kimia dan mikrobiologis sebagai dasar penentu kualitas produk makanan ringan ogel-ogel khas Pemalang agar sesuai dengan peraturan SNI 01-2886-2015. Ogel-ogel berbahan dasar tepung beras ketan yang dicampur dengan telur, keju, gula, dan garam. Selanjutnya adonan tersebut dicetak seperti ulat menggeliat dengan menggunakan ekstruder yang kemudian digoreng. Penelitian dilakukan secara deskriptif dengan parameter uji karakteristik kimia yaitu kadar karbohidrat, protein, lemak, air, abu, garam, logam berat, dan uji ketengikan serta mikrobiologi. Hasil penelitian menunjukkan bahwa ogel-ogel memiliki nilai ketengikan (nilai TBA) 2,16 mg MA/kg; kadar karbohidrat, protein, lemak, air, abu, dan garam masing-masing sebesar 44,75; 13,52; 39,42; 2,51; 0,08; dan 1,87%. Tidak ditemukan adanya kandungan logam berat pada ogel-ogel kecuali timah (10,56 mg/kg) dengan jumlah total mikroba sebanyak 0,87x104 CFU/g. Dapat disimpulkan bahwa secara umum mutu ogel-ogel ditinjau dari karakteristik mikrobiologi dan kimianya telah sesuai dengan Standar Nasional Indonesia tentang makanan ringan ekstrusi (SNI 01-2886-2015) kecuali kadar lemaknya yang masih tinggi. Perlu dipikirkan teknik produksi ogel-ogel dimasa yang akan datang supaya kadar lemaknya lebih rendah sehingga mutunya sesuai dengan SNI. Chemical and Microbiological Characteristic of Ogel-ogel Pemalang Typical SnackAbstractThis study was aimed to get more insight the chemical and microbiological characteristics as a basis for determining the quality of ogel-ogel (snack products typical of Pemalang) to comply with SNI regulations 01-2886-2015. Ogel-ogel made from glutinous rice flour mixed with eggs, cheese, sugar and salt. That dough was molded like a stretched worm by using an extruder and then was fried. The study was conducted descriptively with chemical (carbohydrate, protein, fat, water, ash, salt, heavy metal, and rancidity test) and microbiology (total plate count-TPC) characteristic as the parameters. The results showed that ogel-ogel had a rancidity (TBA) value of 2.16 mg MA/kg; carbohydrate, protein, fat, moisture, ash and salt content of 44.75; 13.52; 39.42; 2.51; 0.08; and 1.87% respectively. No heavy metal content was found in ogel-ogel except lead (10.56 mg/kg) with a total amount of microbes of 0.87x104 CFU/g. It can be concluded that as general, the quality of ogel-ogel in the aspects of microbiological and chemical characteristics was in accordance with the Indonesian National Standard of extruded snacks (SNI 01-2886-2015) except for its high fat content. Further technique to produce ogel-ogel with low fat is necessary to be contemplated to fulfill the quality of ogel-ogel in accordance with SNI.

Humidity-controlled dehydration (HCD) was innovatively applied in this paper to control the growth of microorganisms in fresh wet noodles (FWN). Effects of HCD treatment with different temperatures (40, 60 or 80 °C), relative humidity (RH, 50%, 70% or 90%) and treatment time (5–32 min) on the total plate count (TPC), the shelf-life, and qualities of FWN were investigated. The results showed that HCD reduced the initial microbial load on the fresh noodles and extended the shelf-life up to 14–15 days under refrigeration temperature (10 °C). A 1.39 log10 CFU/g reduction for the initial TPC was achieved after HCD treatment at the temperature of 60 °C and RH of 90%. HCD with higher RH had a more positive influence on quality improvement. The L* values, the apparent stickiness, and the cooking properties of the noodle body were improved by HCD while good sensory and texture quality of noodles were still maintained after the dehydration process.

Bakery items are a vital element of a well-balanced diet, and supermarket shelves now stock a wide range of them. Bakery items are the most popular ready-to-eat foods (REF).Objective:To assess the microbial quality of bakery foods (Bread, Cake and patties) and check the total plate count (TPC), bacterial and yeast count Methods:The analysis of the microbial quality of bakery products was determined for three different bakery products (bread, cake and patties) at ten different locations collected from a renowned bakery in Lahore, Pakistan. The samples were assessed under complete hygienic conditions by standardized plate count (TPC) and MPN method. Micro-organisms (Coliform, Fecal Coliform and Yeast) were lately confirmed by their morphological characteristics and biochemical tests Results: Among the three commodities, bread was found to be highly contaminated by micro-organisms and the total plate count recorded was 4.7 x 105cfu g-1collected from sector I9 which is not consumable. Whereas Patties showed the number of TPC as 1.6 x 105 cfu g-1also collected from sector I9. Cake was revealed as least infected bakery product i.e., 5.7 x 104 cfu g-1. The above results showed that sector I9 is highly contaminated and a threat for health. Bacterial plate count (Coliform and Fecal Coliform count) was highly measured in bread as 460 MPN g-1 taken from sector I5 where as it remains under the permissible limit determined by WHO, 1994 in remaining sectors Conclusions:In conclusion the bakery food is contaminated by the use of un-hygienic water, miss handled during the process after baking i.e., slicing, serving and packaging. To avoid a possible epidemic of food borne illness, competent authorities should conduct a stricter and more stringent inspection of  REFs sold to clients in bakeries.

Line and finished product samples (668) from two shrimp processing plants located at the Karachi fish harbor were collected and examined bacteriologically. Frozen shrimp samples (100) collected from Plant A had the following bacterial profile: average (geometric) total aerobic plate count 9.4 × 106 CFU/g; MPN coliforms 94/g; and MPN fecal coliforms 41/g. The bacterial profile of 114 frozen shrimp samples from Plant B were 8.3 × 106 CFU/g, 180/g and 133/g for total plate count, MPN coliform and MPN fecal coliforms, respectively. Samples (126) of raw and laboratory-processed (simulating commercial processing) shrimp were also examined. Processing conditions of Plant A were better and resulted in a better quality end-product as compared to that of Plant B. Three of 338 samples from Plant B yielded Salmonella. The composition of microbial flora was nearly the same for both species of shrimps from both plants. Pseudomonads were the predominant microflora followed by Micrococcus sp. When shrimp were handled expeditiously under good sanitary conditions in the laboratory, the bacterial counts were significantly lower than on shrimp from the plants. Laboratory-processed shrimp had an average (geometric) total aerobic plate count of 8.1 × 105 CFU/g and average (geometric) coliform and fecal coliform MPNs were <3/g.

Hippoglossoides Platessoides

Fillets of flounder (Hippoglossoides platessoides) and cod (Gadus morhua) produced in two commercial plants from uncut fish that had been frozen in blocks at sea, were free or nearly so of faecal coliforms and generally contained fewer indicator bacteria (all organisms in the coliform group; faecal coliforms) than fillets produced in the same plant from fish iced at sea. Coliforms were found in relatively small numbers on most fillets of thawed fish sampled on the conveyor leading from the mechanical skinner, on similarly prepared fillets sampled after trimming and portioning, and on fillets prepared from fish iced at sea and sampled immediately after skinning. The total plate count on the fillets of thawed fish at the point of trimming and portioning was small, suggesting that the fish frozen at sea carried a relatively low count of fish-spoiling organisms at time of freezing and thawing.The results show that in processing blocks of gutted or gutted and headed fish it is practical to thaw in an immersion thawer at a temperature of 13–20 C while changing the water only infrequently, say every 12 hr, and to employ thawing runs of about 24 hr duration. During this time as many as five tankfuls of fish may be thawed. It is practical also to hold the fish thawed under these conditions in chilled potable water or in crushed ice for 1 or 2 days prior to processing.It was shown that the sanitary aspects of the process can be assessed advantageously by observing the sanitary quality of the fillets, rather than that of the thawing water. The suitability of the method appeared to depend upon efficient washing of the thawed fish before it was put in buffer storage, or before it was filleted, or both. In one of the two plants sampled, large flumes were used and were satisfactory for delivering thawed, washed fish of high bacteriological and sanitary quality from buffer storage to the processing line. Here total plate and coliform counts either increased slightly or decreased slightly with prolonged use of the thawing water and of the boards used in cutting the fillets.

Microbiological Status

The importance of the quality of raw milk increased after Hungary had joined to the EU. On delivery of raw milk, the microbiological quality, especially total plate count of the milk is very important. Twenty-two farms (7 large, 4 medium-sized, and 11 small farms) were included in the study. We considered the different farm size, keeping- and milking circumstances during the selection of farms. The examined large farms use loose housing system (cubicle, deep litter) and milking parlour. Most of them use preand post-milking disinfection. In the medium-sized farms, loose,deep litter and tie-stall housing system, as well as milking parlour, pipeline milking and bucket milking occurred. All of them use preand post-milking disinfection. Small farms use tie-stall housing system, bucket milking and udder preparation by water. Unfortunately, they do not use pre- or post-milking disinfection. In the large and medium-sized farms mainly Holstein Friesian, in the small farms Hungarian Simmental breeds can be found.The aim of our research was to examine the microbiological status of the raw milk produced in dairy farms (total plate count, coliform count, Escherichia coli count, Staphylococcus aureus count, psychrotroph bacteria count, furthermore yeast and mold count); sources of the contamination; connection between the microbiological quality of produced milk and housing-, milking technologies of farms; furthermore the hygienic circumstances of milking and milk handling of the farms, by the examination of coliform bacteria and Escherichia coli contamination.During the examination of the connection between the different farm sizes, various housing- and milking forms and the microbiological characteristics we observed similar tendencies in the case of total plate count, coliform count, yeast and molds count, furthermore psychrotroph bacteria count. The value of  these parameters was significantly higher in small farms, and infarms which use tie-stall housing forms, bucket milking, udder preparation with water, and which do not use pre- and post-milking disinfection.The results showed that besides cooling, the milking procedure and the type of udder preparation had the largest effect on the total plate count. Statistical analysis shows that in medium and small farms the combination of pipeline milking – tie stall housing system – disinfectant preparation of the udder; in large farms the combination of milking parlour – loose cubicle housing system – dry preparation of the udder are the most appropriate in the aspect of the total plate count. We experienced that in farms where the hygienic instructions are not followed – and thereforeequipment used during the milking and handling of milk is very contaminated – or rather the separation of mastitic cows’ milk is not appropriate, different microorganisms may contaminate the produced milk.
