week 10

Assalamualaikum foodies.omg dah masuk week 10 dah rupanye.cepatnya masa berlalu dan kehidupan sbg seorang mahasiswa semakin hari semakin mencabar.hahaha.so during week 10 ni ,sambungan kepada presentation utk kumpulan lain yg belom buat tu.okla.so 1st group talk about cold and heat preservation .cold preservation include refrigeration technique ,cold plasma .of course at lower temperature the miccroorganism activity will be slow down and make sure dont keep fruits vegetables fish too long in refrigeratior .hahahah.cold plasma pula adalah benda baru yg i bljr masa tu.dia adalah technique utk pulihkan semula buah2 yg rosak akibat fungi or mould .so ada satu mesin ini .mesin ini mempunyai gas helium and nitrogen .when we put buah2 yg rosak tadi ke dalam mesin ni pastu kita akan dpt buah yg fresh .magic kn.hehe. bagi heat preservation pula techique nye adalah cooking boiing grilling broiling blanching .korang paham apa itu broilling .broiling ni mcm kita masak makanan dlm oven .heat on top .inches from top oven must be 2-6 inches daripada food tersebut .blanching pula okay .kita boil vegetables then cepat2 masuk kan dlm ice water .begitula citernyeeeeeee.

then proceed dengan presentation canning .okla .canning adalah we replace food inside the container such as tin and then we heating it at high temperature.canning ni sangat bagus and widely use utk preservation pd zaman nowdays.makanan tersebut long lasting and very convinience la sebub lighter and easy to grab.paling penting boleh recycle .okla beralih kpd history nye .nak cerita ckit ni.nicholas appert ni menang hadiah .pastu dia mereka dengan masuk maknn dlm gelas container pastu dia panaskn gelas tu.pastu peter durand pula mengenalkn tin container kebaikkn canning adalah tahan lama dan lebih nutrious value .keburukan nya pula adalah high in sodium ,blood pressure ,banyak syrup high concentration of sugar .so nnti boleh jd diabetes kang susahhhh.hahahaha.satu lagi nk cerita pasal step.mula2 washing and cleaning ,grading,peeling ,blanching ,can filling ,seaming ,retorting ,cooling ,packing dan storage and distribution .itu sja byeeee.

week 9

WEEK 8

ASSALAMUALAIKUM AND SALAM SEJAHTERA .

so this is week 8 .it is very fast and omg mid term tinggal berapa minggu je lagi ni ..semoge everything gonna be alright .so dr.fareeed did not coming to class this week because already informed that he got bad injured on his legs like terseliuh heheh.i hope he will be recovered soon .hehe...!!!so he left to us scl task which is food preservations technique .this task required us to form a group and elaborate about one of the technique that required to be present on 2 november.my group choosed food irradiation.so we discuss among the members about food radiation .so you know what is it??

food irradiation is process of exposing food to ionizing radiation.we will use use xray gamma ray and electron beam radiation .to destroy the microorganisms in the foods .One of the most important advantages of food irradiation processing is that it is a cold process which does not significantly alter physico-chemical characters of the treated product,It can kill many insects and pests that infest foods like grains, herbs and spices without appearing to affect them. It can kill or substantially reduce the level of dangerous micro organisms in foods such as salmonella, listeria and campylobacter. It can delay or stop normal ripening and decay processes so that foods can be stored for longer. It can completely sterilise a food making it fit to eat for vulnerable patients in hospitals.It can only be used on a very limited range of foods. It is still a relatively expensive technology. It affects some important constituents of foods, for example, vitamin E levels can be reduced by 25% after irradiation and vitamin C by 5-10%. Although ordinary cooking will also produce vitamin losses but consumers are more aware of this effect and are likely to sompensate elsewhere intheir diet. Radiation doses at the levels recommended will not kill all micro organisms. Typically 90% may be destroyed and this means that the food still has be treated with care otherwise the remaining organisms will reproduce rapidly. It is ineffective against viruses. It can create new substances called radiolytic products. While this does not mean that the food is radioactive, there is considerable controversy over whether these products are unique and if so whether they are dangerous. 

 

Week 7

ASSALAMUALAIKUM AND SALAM SEJAHTERA ALLS..!!!!

it is already week 7 so i have a task to do .as dr fareed said i nak kene citer kn pasal how food that i eat this week ,how they preserve the food .i mkn almost preservatives food such as sardin ,snacks and many more lah .so one of the foods that i would like to share here is this week i eat i always drink lychee jus .the lychee obtained from the lychee tin to make drink we can buy it in supermarket and they preserve through canning .

So , lychee jus is my favourite drink actually heheh. so now im gonna tell how they process to become last longer and still fresh fruit  .firstly of course we obtained the lychee fruit from farm and plant and then fruit deliberate and sending to unloading bay .the undergo cleaning process which is put into special wash water tank .later the fruits will be grading according to 3 primary grade by considering the sizes.then the fruits will be peeled their coat and pith by slicing machine and resizing machine to make sure they are really clean .after that the lychee will undergo lychee filling and syrup process,the fruits will put onto the cans and filled with concentrated syrup solutions .

after that the tin filled with lychee will admitted into exhausting box to create a vacuum state.the cans need to move to seaming machine and close for air tight .covered cans are then sterilized and they undergo cooling and drying ,by inserting into refrigeration machine and dried by blower.and finally they need to be storage for two weeks to ensure products stability and free from contamination from microorganisms during processing and operation .andnow we can buy it from the retailer and enjoy the freshness of preservatives fruis without need to peel or reoval of skin just open the cans cover and pour it onto your jar .huhuhuhu.nyumyyyy...
