The term "Mata Kucing" (translated as "Cat's Eye") refers to a distinctive visual characteristic of the fruit of Dimocarpus grandiflorus. This name originates from the appearance of its seed, which has a unique pattern resembling the slit - like pupil of a cat's eye when viewed in cross - section or when the seed is cut open.

Key Features:

- The seed contains a dark brown center surrounded by lighter - colored tissue, creating an eye - like appearance with a central "pupil."
- This striking visual feature makes the fruit easily identifiable and gives rise to its common names such as "Mata Kucing," "Kotomato" (in Indonesia), or "Cannonball tree fruit" in English.
Thus, the name "Mata Kucing" directly relates to this notable physical trait of the fruit's seeds.

To identify spoiled or overripe fruits of Dimocarpus grandiflorus (commonly known as the wax apple or Java apple), look for these signs:

Signs of Fermentation:

- Foul odor: A strong, unpleasant smell indicating that the fruit has started to decompose or ferment.
- Change in color: The skin may become discolored, losing its natural vibrant appearance and developing brownish patches or spots.
- Surface texture changes: The surface might feel sticky or tacky due to leaking juices.

Mold Growth:

- Visible mold: Look for fuzzy growth on the surface of the fruit, often appearing white, gray, black, or green.
- Soft spots: Areas where mold is present will usually be softer than the rest of the fruit.

Excessive Softness:

- Loss of firmness: Overripe wax apples lose their crisp texture and become mushy when pressed gently.
- Excessive juice leakage: If the fruit feels wet or squishy and releases liquid easily upon handling, it’s likely past its prime.
If any of these signs are observed, it's best to discard the fruit to avoid potential health risks associated with consuming spoiled produce.

Dimocarpus grandiflorus, commonly known as the wax apple or Java apple (in some regions called "синсин" or "джамбу"), is an exotic tropical fruit native to Southeast Asia. Here are key indicators for identifying when this fruit is fully ripe and sweet:

1. Skin Color

- Ripe: The skin should have a deep, glossy red or purplish - red hue with a waxy sheen. Some varieties may also exhibit green or yellow undertones depending on their specific cultivar.

3. Bring the mixture to a boil, then reduce the heat slightly and let it simmer for about 5 minutes.
4. Add lemon juice or vinegar if desired (this helps prevent discoloration).

Step 3: Sterilize Jars and Lids

1. Sterilize jars and lids. Place them in boiling water for 10 - 15 minutes. This ensures that bacteria are killed before filling.
2. Keep sterilized jars warm. Use a clean kitchen towel to dry the outside of the jars after removing from hot water.

Step 4: Fill and Seal the Jars

1. Fill sterilized jars. Using a slotted spoon, place cleaned longan pieces into the prepared jars, leaving about 1 cm (½ inch) headspace at the top.
2. Pour hot syrup. Carefully ladle the hot syrup over the longan, ensuring that all fruits are fully submerged and no air bubbles remain.
3. Seal immediately. Wipe the rims of the jars clean with a damp cloth, then securely fasten the lids while still hot.

Step 5: Process in Boiling Water Bath (Optional for Long - Term Storage)

If you want to preserve the longan for longer storage (up to a year), process the sealed jars in a boiling water bath:
1. Prepare a large pot filled halfway with water and bring it to a rolling boil.
2. Place jars inside. Ensure they’re covered by at least 1 inch of water above their tops.
3. Boil for 10 - 15 minutes. Start timing once the water returns to a full boil.
4. Cool jars. Remove jars from the boiling water and allow them to cool on a wire rack overnight.

Dimocarpus grandiflorus, commonly known as the wax apple or Java apple, is a tropical fruit that has been used traditionally for various health benefits due to its nutritional content and bioactive compounds. However, like many fruits, it can potentially cause allergic reactions in some individuals.

Allergic Reactions

1. Symptoms:
- Mild symptoms may include oral allergy syndrome (itching or tingling of the mouth, lips, tongue, or throat).
- More severe reactions might involve hives, skin rashes, swelling of the face, lips, or tongue, difficulty breathing, and anaphylaxis (a life - threatening reaction requiring immediate medical attention).
2. Risk Factors:
- Individuals with pollen allergies (such as birch or mugwort pollen) are more likely to experience cross - reactivity with certain fruits, including wax apples.
- People who have previously had allergic reactions to other fruits such as apples, pears, cherries, or peaches may also be at higher risk.
3. Prevalence:
- While allergic reactions to wax apples are not common, they do occur. They tend to be milder compared to reactions from nuts or shellfish but still require caution if symptoms appear.
4. Management:
- If you suspect an allergy, stop consuming the fruit immediately.
- Consult a healthcare provider or allergist for proper diagnosis and management.
- In cases of severe reactions, seek emergency medical care promptly.
In summary, while most people tolerate wax apples well, those with pre - existing food or pollen allergies should exercise caution when trying new foods like this one.
