Besides calories and nutrition, the third factor from foods is critical for human beings, I call it the "emotional nutrients"

This is my theory:

The “emotional nutrients” are more important than simply calories and nutrition, in the era when food supply is higher than people's needs.

About the emotional nutrients (EN),

I think several components determine the value of EN, just like the amino acids composition and amount that affect the value of protein.

 

1. Calories of foods

2. Sensory quality of foods

3. Price of foods

4. Whom you are  with when eating  (family/boy or girlfriend/boss/colleagues)

Sure, spoilage or food poisoning will destroy all the above components

5.  Food taboos of religions, vegan/vegetarian or personal reasons

The reason I write this article is: most nutritional education in Taiwan only emphasizes how calories and nutrition influence our health, and they N-E-V-E-R mention anything about the happiness brought from foods. Thus, I created the term: “emotional nutrients” to rebalance the education in nutrition.

Strange solution (but works) to install LM 20 on new laptop Asus Tuf Gaming FA706IH

Warning: I am not a Linux expert, but the following ways did work (after endless trial and error). It may not apply to other laptops.

This laptop starts to sale on March, 2020. Generally, Linux with newer kernel can support many hardware driver. But this time, it is an exception. You might take risks if you follow my steps.

Conclusion:

1. Turn off secure boot in the BIOS

2. Booting and installing from LM 19.3---kernel 5.0 (unetbootin, USB), with default mode [low support in laptop monitor, cannot find external monitor-HDMI][touch pad  OK, USB mouse OK, wireless OK]

3. Manually install kernel 5.3.18, and reboot. Installing nvidia 440 driver did not support monitor]

https://kernel.ubuntu.com/~kernel-ppa/mainline/

https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3.18/

Why I selected kernel 5.3?  I tried some distro with kernel 5.4 or 5.6, they did not work.

4. updating packages by using update manager (but un-checked the  kernel 5.4,  that was toxic to this labtop)

5. Manually installed kernel 5.7.9

https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.7.9/

When I write this article, the kernel of 5.7.10 and 5.7.11 are available

(I heard about that kernel 5.7 could supper nvidia 1650)

to prevent the update manager  doing stupid things (changing kernel to 5.4),

I hold current kernel:

sudo apt-mark hold linux-image-generic linux-headers-generic

6. reboot-------OK (I cried and cried!). Now It can fully support taptop monitor and external monitor.

Next article,  I will destribe all trial and errors.

Dishwashing Procedures--test

The original link is: https://opentextbc.ca/foodsafety/chapter/workplace-sanitation/

Dishwashing Procedures

Effective dishwashing ensures that all equipment is sanitary and ready for use when required. Using soiled or dirty china is not only dangerous, but it will tell customers that the operator as little or no regard for customer safety. Table 2.5 shows the proper procedures for both manual and automatic dishwashing.
Before washing, scrape dishes and pre-soak any items with hard to remove residue. Then follow the procedure in Table 5, depending on whether you are using a high- or low-temperature dishwasher or you are washing dishes manually.

Table 5. Dishwashing procedures

Step	Manual	High-temperature dishwasher	Low-temperature dishwasher or glass washer
Wash	Use a commercial detergent and 45°C (113°F) water.	Wash cycle must reach at least 60°C (140°F).	Wash cycle must reach at least 60°C (140°F).
Rinse	Rinse in clean hot water.	Hot rinse cycle.	Warm or cold rinse cycle with sanitizer.
Sanitize	Sanitize for 2 minutes with an approved sanitizing solution (50 ppm chlorine or 12.5 ppm iodine).	Rinse cycle must reach at least 82°C (180°F) for at least 10 seconds.	Final rinse must have concentration of 50 ppm chlorine or 12.5 ppm iodine.
Dry	Drain boards should be sanitized and sloped for drainage. Never towel dry.	Drain boards should be sanitized and sloped for drainage Never towel dry.	Drain boards should be sanitized and sloped for drainage Never towel dry.

for verification--test

The following words are about the verification work in HACCP, selected from


HACCP Principles & Application Guidelines, FDA, USA

https://www.fda.gov/food/guidanceregulation/haccp/ucm2006801.htm

And I plan to translate it into Traditional Chinese.
---------------------------------------------------

Examples of Verification Activities

1. Verification procedures may include:
   

1. Establishment of appropriate verification schedules.
2. Review of the HACCP plan for completeness.
3. Confirmation of the accuracy of the flow diagram.
4. Review of the HACCP system to determine if the facility is operating according to the HACCP plan.
5. Review of CCP monitoring records.
6. Review of records for deviations and corrective actions.
7. Validation of critical limits to confirm that they are adequate to control significant hazards.
8. Validation of HACCP plan, including on-site review.
9. Review of modifications of the HACCP plan.
10. Sampling and testing to verify CCPs.

2. Verification should be conducted:
   

1. Routinely, or on an unannounced basis, to assure CCPs are under control.
2. When there are emerging concerns about the safety of the product.
3. When foods have been implicated as a vehicle of foodborne disease.
4. To confirm that changes have been implemented correctly after a HACCP plan has been modified.
5. To assess whether a HACCP plan should be modified due to a change in the process, equipment, ingredients, etc.

3. Verification reports may include information on the presence and adequacy of.
   

1. The HACCP plan and the person(s) responsible for administering and updating the HACCP plan.
2. The records associated with CCP monitoring.
3. Direct recording of monitoring data of the CCP while in operation.
4. Certification that monitoring equipment is properly calibrated and in working order.
5. Corrective actions for deviations.
6. Sampling and testing methods used to verify that CCPs are under control.
7. Modifications to the HACCP plan.
8. Training and knowledge of individuals responsible for monitoring CCPs.
9. Validation activities.
   

Establish verification procedures (Principle 6) 
Verification is defined as those activities, other than monitoring, that determine the validity of the HACCP plan and that the system is operating according to the plan. The NAS (1985) ⁽²⁾ pointed out that the major infusion of science in a HACCP system centers on proper identification of the hazards, critical control points, critical limits, and instituting proper verification procedures. These processes should take place during the development and implementation of the HACCP plans and maintenance of the HACCP system. An example of a verification schedule is given in Figure 2.
One aspect of verification is evaluating whether the facility's HACCP system is functioning according to the HACCP plan. An effective HACCP system requires little end-product testing, since sufficient validated safeguards are built in early in the process. Therefore, rather than relying on end-product testing, firms should rely on frequent reviews of their HACCP plan, verification that the HACCP plan is being correctly followed, and review of CCP monitoring and corrective action records.
Another important aspect of verification is the initial validation of the HACCP plan to determine that the plan is scientifically and technically sound, that all hazards have been identified and that if the HACCP plan is properly implemented these hazards will be effectively controlled. Information needed to validate the HACCP plan often include (1) expert advice and scientific studies and (2) in-plant observations, measurements, and evaluations. For example, validation of the cooking process for beef patties should include the scientific justification of the heating times and temperatures needed to obtain an appropriate destruction of pathogenic microorganisms (i.e., enteric pathogens) and studies to confirm that the conditions of cooking will deliver the required time and temperature to each beef patty.
Subsequent validations are performed and documented by a HACCP team or an independent expert as needed. For example, validations are conducted when there is an unexplained system failure; a significant product, process or packaging change occurs; or new hazards are recognized.
In addition, a periodic comprehensive verification of the HACCP system should be conducted by an unbiased, independent authority. Such authorities can be internal or external to the food operation. This should include a technical evaluation of the hazard analysis and each element of the HACCP plan as well as on-site review of all flow diagrams and appropriate records from operation of the plan. A comprehensive verification is independent of other verification procedures and must be performed to ensure that the HACCP plan is resulting in the control of the hazards. If the results of the comprehensive verification identifies deficiencies, the HACCP team modifies the HACCP plan as necessary.
Verification activities are carried out by individuals within a company, third party experts, and regulatory agencies. It is important that individuals doing verification have appropriate technical expertise to perform this function. The role of regulatory and industry in HACCP was further described by the NACMCF (1994) ⁽³⁾.
Examples of verification activities are included as Appendix G.
