Chinese fast food for cooking oil, how to make a blind comparison of four foods.

To replace cooking oil, ask whether there are interesting differences in the same dish under the same conditions and whether these differences affect the whole menu. One oil is placed in a small batch of small pots and the other in a full load of large pots. A comparison of the two sets of cooking conditions is obtained, and the results cannot be fully attributed to the oil. Nor can a blind evaluation prove that a particular oil is healthier or can extend its useful life.

An in-house comparison of the two compliance oils is discussed below, using as a scenario a fast-food restaurant with a cutter. It does not contain real test results, nor is it an oil safety test. The original reference article dealt with deep-dry oil for commercial use, covering factors such as price, flavor and application; these questions could be a source of inspiration, but the cooking conditions, oil rankings and number of smoke spots could not be moved directly into medium-scrambling. [1]

Four dishes are not a four-choice dish.

The first category of selected leaves tastes relatively light, depending on whether they are masked as odour, surface oil and raw material. The second type of door-shopping is frequently provided with a pickle to observe the actual acceptance of sauce and finished products. The third category is a common protein dish, which evaluates the taste and taste of a cooked condition. The fourth category selects the staple food or gravy with starch, with a focus on the oily feeling and the residues in the pot. The categories are intended only to cover different tasks and cannot be used to predetermine which oil is more suitable for which category.

Selecting a regular dish for each type from the recent real distribution structure is more useful than testing a temporary invention menu. High-sale, but high-savory, foods cannot be packaged, and very low-sold, but very difficult to produce, do not represent the day-to-day business. If the door store does not have a certain type of dish, it replaces it with another task with a differentiated value, with an indication of the menu coverage and without the need for a full name.

The selection locks the feedstock binding, the initial state, the asphalting method, the flavour formulation and the per pot input. One pot of freshly washed leaves cannot be used, and the other one with full asphalt; the conditions are different even if the weight is the same. When the original batch of food is not sufficient to complete the whole group, a separate group should be set up, rather than sneaking into different feedstocks.

One round answers only "What happens when oil is replaced" and not replace equipment at the same time

The two oils were replaced by three blind codes without branding. The coding forms are kept by persons who do not participate in the sensory rating, but the person in charge of security management must be able to identify the true content and the batch. Blinding laws cannot be a reason for concealing ingredients or for testing the unsuited. Candidate products continue to be managed according to the requirements for the acquisition, identification and storage of raw materials, and non-comparison of non-compliant products. [2]

The two pots of the same dish are of the same type, the same boiler, the same quantity, the same oil quality, the same operating procedures and the same familiar requirements. Manually, as far as possible, is performed by the same person and actual deviations are recorded; the procedure is retained and adjustments are allowed when the automatic screeching device is used instead of only " automatic mode " . These conditions do not require the same food cutter, but only the same candidate for the same dish.

The amount of oil is initially controlled by a nominal amount and is not re-indirected. The first round answers the difference in the finished product in the case of the equivalent; if the next round is to examine whether a certain amount of oil is less, a separate quantity test should be set up and no “better” can be declared on the sideside of the first round. The boiler is returned to a comparable state in accordance with established cleaning requirements, so as to avoid the impact of the last remaining pot on the next pot or to alter the cleaning agent ' s concentration to accommodate a certain amount of oil.

A first-cycle door shop is normal and within the limits permitted by the equipment. A new test layer is required for a peak mass or another device: within that layer, the same conditions will still apply to the two oils. The result may be “unvisible differences in small batch conditions, with a large number of conditions to be judged”, rather than the forced synthesis of a full scene champion.

It's a better order. It affects judgment before the brand is revealed.

If paragraph 1 is always fired first, temperature, waiting and assessment fatigue may be tied to oil identity. The order of rotation can be arranged under safe and normal conditions of supply, and the time between completion and evaluation is maintained. It is not possible to leave the first waiting period to the table, but to consider the changes caused by the longer waiting period as a disadvantage of oil.

For example, if the first round of leaves are taken in the order of the first, the next round is changed to the number of the second. The same time requirement set for each dish is implemented from completion to evaluation. This is only an example of a balanced sequence, which does not mean that two rounds would be sufficient to arrive at a statistical conclusion; additional independent observations are also required when there is a greater change in personnel, vegetables or course.

Each review is independent and discusses differences. A five-degree rating can be applied uniformly, but observations such as "Evident Frozen Scorture" and "Most Like" are separated. The difference of one score does not automatically amount to an operational value, much less to cover up the apparent non-acceptance of a particular major course. In the event of a suspicious security anomaly, the evaluation is discontinued and disposed of in accordance with the requirements and the risk is not ruled out through trial feeding.

There is also a distinction between “how many people evaluate” and “how many pots have been made independently”. The distribution of a pot to 10 people only shows how 10 people feel about the same pot, which does not mean that 10 cooking times have been completed. For operational fluctuations to be understood, they have to be recreated in another round under comparable conditions; this cannot be supplemented by repeated tastes of the same pot. The results are recorded in a manner that separates the field, the pot and the number of people who are evaluated, and it follows that a difference is observed only in one pot or still on different occasions. The preferences of internal participants do not necessarily represent the entire customer, and it is not advisable to recast the result as a consumer acceptance rate.

A four-class emptiness table with an original evaluation that can be reset.

The following is the complete frame, the spaces are to be observed and do not mean that the test has been completed. Each of the two oils has a single record, which corresponds to the same one with the same dish name and condition. Residues in the pot and the clearing field are observed separately by the operator and not by those who only eat the finished product.

It's our place.	Blind code and wheel time	Description and acceptance of finished products	Residues and field observation
Vegetable: name to be filled	To be filled	Smell, smell, oil: To be filled	Attach position, restore action: to be filled
Sculpture: To be completed	To be filled	Juice performance, entrance experience: to be filled	Juice position, recovery action: to be filled
Protein: to be filled in	To be filled	Favorite, taste, objection: to be filled	Bottom residue, recovery action: to be filled
Stard powder: to be filled in	To be filled	Oilyness, acceptance level: to be filled	Sticky range, restoration action: to be filled

It also includes the corresponding material quality, oil quality, procedures, operators and time of completion. They are the necessary context to explain the difference and need not be crowded into every sense. If the site is to be cleared, the boundary should be harmonized from the time it is allowed to start cleaning to the time it meets the established clean-up requirements; not a single item should be emptied, and a single item should include cooling waiting.

After reading, find a record of damaged conditions. For example, the data on the b-code, which corresponds to a pot of raw materials with insufficient asphalt, is maintained and marked with deviations, does not delete adverse results and is not directly used for the evaluation of oil. A comparison of the conditions is more reliable than an explanation of the taste by the evaluation memory.

Let's make a decision about cooking, and then we'll decide whether to use the oil.

Assuming that three of the four dishes are acceptable, only the highest-sold leaves would have a consistent negative picture of a candidate. It is not possible to declare a “three to one” overall victory at this time, and an analysis should be made as to whether the cabbage needs to be independently oiled, whether it will increase storage and operational complexity, or whether it will not be replaced. This is a hypothetical decision-making situation, not an evaluation of any oil species.

Costs have also been recosted according to the same task: comparing procurement costs with those associated with oil for quality, with a separate record of losses and additional operations, with more than a barrel price. The difference between barrel weights and promotion cycles does not allow for direct comparison of amounts; the difference in field clearance observed in the blind review is not immediately converted to annual labour savings.

Ultimately, three results can be retained: acceptance by course, non-acceptance by course and insufficient evidence. Changes in supply batches, new menus or changes in equipment conditions may need to be re-referenced. The effect of blind ratings is to reduce the disruption of brand impressions to the judgement of the finished product and to link the decision to change oil to the actual food in the door, rather than to package a subjective preference into general nutritional, safety or economic conclusions.
