Selection method for canned tuna

Packaging observation: Observe whether the outer packaging is clean and tidy, whether the handwriting and printing are clear, and whether it is within the shelf life. Also, check whether the food label indicates the company's name, address, contact phone number, and other information. Check the internal quality: For products packaged in glass bottles, the shape of the contents can be observed to be intact, without foreign objects or turbidity. Normal products have a certain degree of vacuum, and there is a crisp sound when knocking on the bottle cap. If there is no vacuum, there is a high possibility of quality problems in the product. Prevent "chubby listening": Do not purchase products with changes in appearance. When canned food is contaminated by microorganisms and loses its edible value, it often leads to the phenomenon of "chubby listening" of the product, which is an increase in the volume of the outer packaging.

Development and process requirements of canned tuna

Canned tuna is an important variety of canned aquatic products. The main types of canned tuna used for processing are long finned tuna and yellow finned tuna. There are many types of canned tuna, including raw tuna, fragrant tuna, oil immersed tuna, vegetable tuna, and eggplant juice tuna. In addition, due to the high content of sulfur-containing proteins in tuna muscle, sulfur and acid resistant fully coated tin cans are generally used as containers for canned food. Raw material acceptance: The hygiene quality should comply with the relevant provisions of GB2733-94 Marine Fish Hygiene Standard. It is not allowed to use spoiled fish with a second level freshness or lower. Raw material processing: Wash fresh fish with clean water. Frozen fish shall be frozen in flowing water, and the frozen fish shall be completely frozen with no change in quality. Steaming: The steaming time should be determined based on the size of the raw fish and strictly controlled. Sorting: The steamed fish body should be thoroughly cooled to make the tissue tight and firm, and then sorted to avoid breakage. Canning: Use 860 grade sulfuric acid resistant dual-purpose fully coated tin cans that comply with the specifications of GB10785-89 Open Top Metal Round Can Series. Vacuum sealing can: After sealing the can, it should be cleaned with detergent and water to remove fish residue and oil stains attached to the outside of the can. Then, it should be placed in a sterilization basket (cage) for sterilization. Sterilization: After sealing the can, it should be sterilized as soon as possible. During the sterilization process, it is necessary to strictly follow the operating procedures to avoid causing defective or waste products. The sterilization procedure is: 15 ˊ- sixty-five ˊ- Reverse pressure cooling/121 ℃.

A brief history of the development of tinplate

1810: The world's first tin can was invented by the British and patented. At that time, a can making expert could make 60 empty cans in a day. 1900: Invented welding machine. In 1847, the United States invented the canning machine, replacing manual labor. In 1965, aluminum easy to open lids began to be used in can making. In 1973, Tie Yi Kai lids began to be used in can making. In 1990, the canning technology was improved to produce over 1000 cans per minute.

What does tinplate material mean

Tin plate, also known as tinplate, is made by plating tin on a thin steel substrate. The base material of thin steel plate is made of low-carbon steel, with a thickness generally ranging from 0.1 to 0.4mm. Tin plate: Zn, Fe alloy (Zn is the coating) Tin plate is a common name for electroplated tin thin steel plate, abbreviated as SPTE, which refers to cold-rolled low-carbon steel plate or strip coated with commercial pure tin on both sides, also known as tinned iron. Tin mainly plays a role in preventing corrosion and rusting. It combines the strength and formability of steel with the corrosion resistance, solderability, and aesthetic appearance of tin in a single material, with the characteristics of corrosion resistance, non toxicity, high strength, and good ductility. In acidic environments, the tin protective layer of tinplate comes into direct contact with the outside world, providing protection to the substrate due to the slow corrosion rate of tin. If there are defects such as pinholes and cracks on the tin protective layer, some of the substrate will be exposed, leading to rapid corrosion of the substrate. Tin plate is an iron sheet coated with a layer of tin on the surface, which is not easy to rust, also known as tinned iron. Tinplate was born prematurely in Bohemia (now within the Czech Republic and Slovakia). The area has been rich in metal production since ancient times, with advanced technology and knowledge of using hydraulic power for machine manufacturing. The production of tinplate has been ongoing since the 14th century. For a long time, this place has been the main producer of tinplate in the world. At that time, tinplate was mainly used to make tableware and drinking utensils. The origin of the name tinplate Tinplate, also known as tinplate in the early days, should be officially called tinplate steel sheet. Because the first batch of foreign iron in China was imported from Macau in the mid Qing Dynasty, which was transliterated as "Ma Kou" at that time, Chinese people generally referred to it as "Ma Kou". Tinplate originated in Bohemia (now within the Czech Republic and Slovakia). The area has been rich in advanced metal craftsmanship since ancient times, and knows how to use hydraulic power for machine manufacturing. It has been producing tinplate since the 14th century. For a long period of time, this place has been the main producer of tinplate in the world. At that time, tinplate was mainly used to make tableware and drinking utensils. In the 17th century, Britain, France, and Sweden all hoped to establish their own tinplate industry, but due to the need for large amounts of funding, it was delayed in development. It was not until 1811, when Brian Downing and John Hall founded canned tinplate food, that tinplate manufacturing began to develop on a large scale. Nowadays, the world produces about 250000 tons of tin annually, with over one-third used to manufacture tinplate, most of which is used in the canned food industry.

Do canned foods require preservatives

Canned food is a very delicious food, and many people love to eat it. Most of the canned foods we eat are usually canned fruits or canned meat. These two types of canned foods have a good taste and are usually made in the pickling process. In order to keep the canned food for a longer period of time, some substances that can increase its shelf life are added inside. Will there be any preservatives in the canned food? Many people feel that canned food can be stored for such a long time because there must be preservatives, but in fact, there are no preservatives in canned food. The spoilage of food is mainly caused by microorganisms under appropriate conditions. To prevent microbial growth, various measures can be taken for control, such as canned storage. Canned food is preserved by sealing it first, then heating and sterilizing it, completely killing microorganisms in the food. After a certain period of high-temperature heating, the microorganisms in the canned food are eliminated; At the same time, because it is already sealed, microorganisms in the environment cannot enter the can. Due to the control of microorganisms, canned food can be stored for a long time. "Ultra high temperature heating followed by sterile packaging" is another commonly used solution for long-term preservation of food in the food industry. Its principle is similar to canned food, which is to kill microorganisms by ultra-high temperature heating, and then sterile packaging is carried out in a sterile environment to prevent microorganisms from entering, thereby achieving anti-corrosion without the need for preservatives.

How is canned food preserved?

In fact, most canned foods are non additive, let alone added preservatives. Only a few canned foods, due to factors such as limited craftsmanship, will be added with standard range preservatives, which are not harmful to the human body. Generally speaking, when making canned food, it is necessary to preprocess its raw materials. Next, a series of processes including canning, exhaust, sealing, sterilization, cooling, insulation inspection, packaging, etc. are completed. This is the manufacturing process and technique of canned food, and it is precisely this special manufacturing technique that ensures the "no additives" of canned food. In addition, canned food is mainly pasteurized and completed after canning. Generally speaking, pasteurization can kill the vast majority of microorganisms in food. At the same time, the packaging of canned food is also very particular, using tin sheets and other materials to ensure its good sealing. This also prevents food from producing microorganisms again. Therefore, canned food can still ensure a long shelf life even without adding preservatives.

Is canned food nutritious?

For most ordinary people, canned food is defined as non nutritious food. However, the truth of the matter surprised everyone that canned food is not a product without nutrition. Because canned food is pasteurized and the temperature control is appropriate, it effectively preserves most of the nutrients in the food itself. Only a small portion of heat-resistant vitamins will be processed during the sterilization process, but the impact is not significant. Indeed, many people have always had misunderstandings about canned food, believing that canned food is not nutritious and contains a large amount of preservatives. In fact, canned food is not as scary as people imagine, and consuming it in moderation is also harmless.
