Example Input: I regularly purchase this item in the bulk and loved it because it was also dairy free. However, my last purchase was disappointing, after opening a brand new package I noticed a black thing in the mix, carefully removed to find out it was a dead flour beetle! I sifted the mix and found more DEAD BUGS!  This is the second time I writing this review. Amazon didn't publish my first review. Thank you AMAZON. I will not be purchasing this item again.
Example Output: 1

Example Input: Ingredient list: Sugar, Acidity Regulator (including miscellaneous chemicals). No tea whatsoever. $22 for 18 oz. (500g) of sugar with apple flavor. Most expensive sugar in the market!! Health benefit? None! It comes in a square tin with plastic bag inside containing granulated sugar. That's all. Nothing more.
Example Output: 1

Example Input: This coffee is only mediocre in quality. I do not like a highly acidic coffee nor do I like it when the coffee outdates within 6 weeks of the order date. The only reason I am not more dissatified with this lousy coffee is that I paid very little for it by using a credit I had at amazon payments. I do not recommend this coffee.
