Conclusion Aside from the healthy nutritional profile of pineapple, here’s what the current research says about the potential health benefits of this fruit: Inhibition experiments indicated similar IgE reactivity of natural and recombinant allergen (Reindl et al. 2002) Pineapple fruit extract comes from the core and stem of the pineapple fruit. This fruit extract contains bromelain, which is a group of enzymes rich in alpha hydroxy acids (AHAs). Pineapple extract also contains magnesium, phosphorus, and potassium. Pineapple Extract Uses for Skin Bromelain extract is a mixture of protein-digesting ( proteolytic) enzymes and several other substances in smaller quantities. The proteolytic enzymes are sulfhydryl proteases; a free sulfhydryl group of a cysteine amino acid side chain is required for function. The two main enzymes are:

Knowing what can be used instead of pineapple is especially important for people who are allergic to this tropical fruit or have a hard time finding fresh pineapple in their local stores. The Best Substitutes For Pineapple In this study, chitosan films were successfully developed with pineapple peel extracts. The significant polyphenols of the pineapple peel extracts were identified and quantified through LC-MS/MS which attributed to the antimicrobial and antioxidant properties of the chitosan films. The total phenolic and flavonoids content of ethanolic and methanolic pineapple peel extracts were found to be in correlation with their corresponding antioxidant activities. The antioxidant capacity of the pineapple peel extracts was retained to a considerable extent when incorporated in the chitosan films. Canned pineapple is the best substitute for fresh pineapple. It can replace fresh pineapple in nearly all recipes.

However, even in people without an allergy or diabetes, eating too much pineapple — more than a few servings per day — may have unintended side effects.

The term "bromelain" may refer to either of two protease enzymes extracted from the plants of the family Bromeliaceae, or it may refer to a combination of those enzymes along with other compounds produced in an extract. [1] Bromelain enzymes are called fruit bromelain and stem bromelain.

Int J Oral Maxillofac Surg. 2019;48(5):651-658. doi:10.1016/j.ijom.2018.07.028 Pineapple, if paired well, is also a great ingredient in savory dishes containing seafood, poultry, and pork.

Protocol: (controls, definition of positive etc) Histamine chloride (0.1%) and NaCl (0.9%) were used as positive and negative controls, respectively (Nettis et al. 2001)That said, you’d likely need to eat a large amount of pineapple alone to notice a difference in your skin. Instead, try including pineapple as just one component of a healthy and balanced diet. Summary

Pineapple consumption reduced cardiac oxidative stress and inflammation in high cholesterol diet-fed rats. (2021). The chitosan films were prepared according to the method [ 28] with slight modifications. Briefly, a chitosan solution of 2% (w/v) was prepared in 1% (v/v) acetic acid. The solution was stirred overnight at room temperature until it got completely dissolved. Glycerol (1.5 ml/g polymer dry matter) was added as a plasticizer and stirred for 30 min. To that solution, PEE and PME were added to reach a final concentration of 1% (w/v) and stirred for 30 min. The film-forming solutions, CH-PEE, CH-PME, pure chitosan (CH) film (as control) were poured on plastic plates and dried for 48 h at 40°C. The dried films were stored in a desiccator (ABDOS E11612, India) at 25°C until further analysis. 2.8.1.

In products that contain pineapple fruit extract, it’s common to see papaya fruit extract as an ingredient as well. Papaya and pineapple enzymes offer similar benefits so these ingredients go well together. Pineapple Enzyme Masks

Papaya and guava juices are also good options if these are what you have at hand. In the case of guava juice, however, use the juice from unripe guavas for a sweet and sour flavor. If you want to get as close as possible to the flavor of fresh pineapple, you might need to go for fruit combinations. Think of pineapple as the younger, trendier vitamin C ingredient. It just wants to lay by the pool in a bikini (in the shade, of course). Pineapple extract also pairs well with others, so plenty of products below contain fruit enzymes from papaya, pumpkin, and more. Ingredients: We value natural ingredients, as those provide the best flavors! However, a lot of pineapple extracts contain some artificial ingredients, so we try to limit them as much as possible.
