Home Food Safety Self Inspection Plan

Today, as food safety is increasingly valued, we are pleased to see that the national regulatory system is becoming more and more perfect. However, as the ultimate link in food consumption, mastering convenient self testing methods in the family can add an active guarantee to our daily dining table. As Hengmei Electronics, which is deeply involved in the field of food safety rapid inspection, we are committed to bringing professional level testing capabilities to ordinary people's homes, and building the first line of defense for your family health with technology.

Ⅰ.Common Objectives and Significance of Home Food Safety Self Inspection

• Pesticide residues: There may be a risk of exceeding the standard of organic phosphorus, amino acid esters and other pesticides on the surface of fruits and vegetables.

• Illegal additives: such as clenbuterol and ractopamine in meat, malachite green in aquatic products, and preservatives or bleaching agents that may be abused in some foods (such as sulfur dioxide).

• Harmful microorganisms: Although they cannot completely replace laboratory cultivation, they can quickly screen hygiene indicators of some ingredients (such as tableware surfaces and meat) (such as ATP bioluminescence method).

• Partial heavy metal pollution: potential risks such as lead, cadmium, etc. in certain specific food ingredients (such as rice, shellfish) (requiring specialized equipment).

• Meaning: Enhance risk awareness, assist in selecting safer ingredients, timely identify potential problems, and strengthen family dining confidence.

Ⅱ.Hengmei Technology: Your Home Food Safety Guardian Partner

Hengmei Electronics focuses on the research and application of food safety rapid detection technology. Our home series detectors are designed with the concept of "precision, speed, and simplicity", condensing complex laboratory testing processes into easy operation at the fingertips, making professional protection within reach.

Ⅲ.Home Self Inspection Operation Plan 

The following plan is based on the typical functional design of Hengmei household rapid testing instruments. Please refer to the detailed manual of the instrument you purchased for specific operation.

1.Rapid screening of pesticide residues in fruits and vegetables:

• Preparation: Hengmei HM-NC series pesticide residue detector, supporting reagent tablets, and fruit and vegetable samples to be tested (such as vegetables and apples).

• Sampling: Take a small amount of edible skin (or whole) of fruits and vegetables and cut them into small pieces of about 1cm.

• Extraction: Place the sample into an extraction bottle, add a specified amount of purified water or buffer solution, shake or let stand for a certain period of time to extract.

• Testing: Take an appropriate amount of extraction solution and add it to the reagent kit provided by Hengmei Instrument. Place the reagent tablets into the Hengmei HM-NC detection chamber.

• Interpretation: Start the Hengmei detector. The instrument is equipped with an optical sensor that automatically analyzes the color change of the reagent strip, and within a few minutes, the results are displayed directly on a clear screen: "qualified", "exceeded", or specific inhibition rate values. Hengmei Instrument's intelligent algorithm ensures that the results are clear at a glance.

2.Meat clenbuterol/ractopamine rapid detection:

• Preparation: Hengmei HM-SSJ series food safety comprehensive detector, clenbuterol specific detection card, meat samples (pork, beef, etc.) to be tested, extraction solution.

• Processing: Take a small amount of meat sample (lean portion) and grind or cut it finely.

• Extraction: Add Hengmei supporting extraction solution, shake and mix thoroughly, let it stand or centrifuge to obtain the supernatant.

• Detection: Use a dropper to extract the supernatant and add it dropwise to the sample well of the Hengmei clenbuterol detection card.

• Interpretation: Place the detection card horizontally in the dedicated card slot of the Hengmei HM-SJ instrument. Start detection, the instrument automatically reads the signal strength of the detection line (T line) and quality control line (C line), accurately determines whether it is negative (not detected) or positive (detected), and avoids visual interpretation errors.

3.Rapid detection of food additives (such as sulfur dioxide):

• Preparation: Hengmei  food safety comprehensive detector , sulfur dioxide dedicated detection kit, test samples (such as dried edible mushrooms, Tremella fuciformis, vermicelli, etc.).

• Processing: Crush or cut the sample.

• Distillation/Extraction: According to the instructions of the Hengmei reagent kit, a simple distillation device (simplified version for home use) or direct immersion in the extraction solution may be required.

• Color development: Take the processed solution and add Hengmei's matching color developer.

• Testing: If HM-SP is used, it is usually paired with a colorimetric tube or dish and placed in the instrument's colorimetric slot. If using HM-FJ series spectrophotometric instruments, the colorimetric solution needs to be injected into the colorimetric dish and placed in the instrument.

• Interpretation: Start the Hengmei detector, the instrument automatically measures the absorbance of the solution, calculates the sulfur dioxide content based on the built-in standard curve, displays the result on the screen (such as mg/kg), and prompts whether it meets the common limit standards.

4.Quick detection of surface cleanliness (ATP) of tableware/objects:

• Preparation: Hengmei HM-ATP series fluorescence detector, dedicated ATP swab.

• Sampling: Apply a Hengmei ATP swab to the surface of the object to be tested (such as dishes, cutting boards, countertops), and rotate and apply in the prescribed manner.

• Activation: Break the swab rod to allow the liquid reagent to flow into the swab head and fully react with the sample.

• Testing: Immediately insert the swab into the Hengmei HM-ATP detector.

• Interpretation: Start the detection, the instrument detects the luminous value (RLU) within ten seconds, the screen directly displays the value and gives visual prompts such as "pass", "alert", "fail", etc., quantitatively evaluating the cleaning effect.

Ⅳ.Key Tips for Home Self Inspection

• Instrument selection: Choose the professional model corresponding to Hengmei based on the most common risk points of concern in the family (pesticide residues, clenbuterol, additives, etc.). The HM-SJ series typically has high integration and is suitable for multi item testing; HM-NC, HM-ATP, etc. are optimized for specific projects.

• Standardized operation: Strictly follow the instructions of Hengmei instruments and supporting reagents, including sampling volume, reaction time, temperature, etc., which is a prerequisite for reliable results.

• Reagent storage: Hengmei's supporting reagents should be stored as required (usually refrigerated and protected from light) and used within their expiration date.

• Result interpretation: The intelligent interpretation of Hengmei instruments greatly simplifies the process. Understand the meaning of "negative/positive", "qualified/exceeded" or specific numerical values. Any self inspection positive or excessive results should stop consuming the batch of food and can be sent to a professional laboratory for retesting or reported to regulatory authorities.

• Limitations cognition: Home rapid testing is a screening method with the advantages of speed and convenience, but its testing scope and accuracy cannot completely replace the authoritative laboratory testing of government regulatory departments. It is mainly used for risk screening and enhancing awareness.

• Regular maintenance: Clean and calibrate the instrument according to the instructions of Hengmei (if any) to ensure that it is in good working condition.

Ⅴ.Hengmei Technology: Make Anxin Visible

• Hengmei Electronics deeply understands the expectations of families for food safety. Our household testing instruments integrate years of technological accumulation:

• Accurate and reliable: The core sensors and algorithms are sourced from professional equipment, ensuring reliable detection results.

• Minimalist operation: process optimization design, large screen Chinese guidance, easy to get started without professional knowledge.

• Fast and efficient: Results can be obtained in just a few minutes to over ten minutes, without delaying cooking arrangements.

• Compact and portable: designed specifically for kitchen space, easy to store, and convenient to use anytime.

• Intelligent interconnection: Some models support data recording and Bluetooth transmission, making it convenient to manage household food safety records.
